A lightweight peptide serum containing a 30% peptide complex, including matrixyl, copper peptides, and growth factors, designed to support skin firmness and reduce visible signs of aging.
This serum earns consistent praise for its unusually high peptide concentration and research-backed blend (particularly matrixyl 3000 and copper peptides) that visibly plumps and firms skin without the price tag of luxury alternatives. Gurus highlight the light, watery texture and note it pairs well under retinol or as a standalone hydrating layer. The one catch: copper peptides can be finicky for some skin types, so those new to peptides may want to patch-test first and those with sensitive skin should introduce it slowly.

"My current go-to when it comes to growth factors is the Medicate Liquid Peptides Advanced. I love this product because it contains bio-engineered skin compatible growth factors. These are the ones that are already present in our body and so the skin recognizes them as a friend, welcomes them in and you get those super quick results."
"It's not going to be in everyone's budget, but I think for the quality of the growth factors you're getting here, it's definitely leveled up. I really do prioritize growth factors in my skincare routine, so I leveled up by going for this. I just couldn't stretch to some of the bougier, more expensive options. Medik8 is that beautiful mid-market price delivering that top-notch growth factor action without necessarily costing an arm and a leg to be able to afford it. Just really, really nice."
Top 5 ULTIMATE SKIN FIRMING SERUMS - Best Anti Aging Routine Yet
"A great alternative you could go for is the Medik8 Liquid Peptides Advanced MP+ Serum. Very similar formulation, same great advanced growth factors action going on, but a third of the price of the Allies of Skin one. So it really takes that price point down while still maintaining the results that you're going to see."
Next Generation Botox In A Bottle - BEST PEPTIDE SERUMS 2026
"The liquid peptides advanced is the liquid peptides formula with growth factors added in. [...] Growth factors are a great subset of peptides that have some additional pro-collagen benefit. So if you're using the liquid peptides and you really want to dial up the results you see, go for the liquid peptides advanced and get that extra dose of growth factors."
"So you can make a huge cost saving and still get some really really great results. I think this is a great midmarket price point that allows you to get those growth factors and peptides together and it just feels so beautiful on the skin. This is one of their latest launches and I think this has really reinvigorated people's excitement in Medik8 as a brand and for good reason."
PEPTIDES - Better Than Botox Or Skincare Scam
"This used to be my go-to and my favorite. [...] This is an original and I think it deserves a lot of credit because Medik8 were the first ones to do high quality, high dose peptides really effectively. This is a great all-rounder, and whilst it's slightly more expensive than some of the others, I think if you're the person who likes to go with the OG, the best peptide serum around, I don't think you can go wrong with this multiple peptides, high dose formulation. Just a great all-rounder."
Ultimate HYPERPIGMENTATION ROUTINE - My Morning Skincare Routine For Dark Spots
"I love it. You've got a dose of peptides in here, too. If your budget doesn't stretch to this one, I have got a discount code for this, by the way, which I use when I buy it myself. [...] I do one and a half pumps of this for the whole face. I find that works and I rub that in. For me, this is the best. This is peak. It's peak growth factors. [...] This is my one splurge item that I always buy."
No1 Anti Aging - TOP 10 PEPTIDE SERUMS 2025
"I think this is a really great example of a brand taking a cult holy grail product and improving it. [...] The Medik8 one works best for people that are tempted by the Ally Skin but can't quite reach that price point. It's around half the price of Ally Skin. It's not quite the same, but it's the closest you're going to get as a dupe. And if your budget doesn't stretch to that, then the Medik8 one is like half the price, which is why it's in third position on this list."
"It's a much more affordable price point than the Allies of Skin and also uses that biocompatible blend of growth factors. So definitely going to pack a punch, have a quicker turnaround in terms of results. Now this one doesn't actually have as high a concentration of growth factors as the Allies of Skin, but you're paying roughly half the price. So there is a little bit of a trade-off here when it comes to more affordable, but you're not getting quite as much of that growth factor technology."
BEST GROWTH FACTOR SERUMS 2026 (For Every Budget)
"This is the one that I reach for the most. I just love this product. It launched I believe around the time of the Ordinary growth factors, so around 18 months ago. And I know so many people that have never skipped a day using this and are getting great results. I love the fact that you're getting a great blend of peptides in this. It's got a 30% concentration of peptides, which is super high. You've also got those growth factors added on in order to give us some next level benefits."
Its Official: BOTOX IN A BOTTLE JUST LEVELLED UP - Argireline Serums (6 Year Update)
"This is the most advanced Azureine containing serum on the market. [...] This has it all. You've got that Azureine for that instant reduction in fine lines and wrinkles. You've got a blend of other peptides to plump, hydrate, deliver long-term collagen production. You've also got growth factors, which are a subset of peptides and some of the very best when it comes to boosting collagen in the long term. I love growth factors."
'Miracle' $20 COPPER PEPTIDE SERUM - Is This The Future Of Anti Aging?
"The Medik8 Liquid Peptides Advanced is to my knowledge the actual world first. This is the first serum that I'm aware of that combined copper peptides alongside growth factors in the same serum. [...] The growth factors that they use are a more enhanced form, so you're going to get greater results. Yes, you're paying a little bit more, but I think you're getting more for paying more. If [...] your budget will stretch to the Medik8 one, I think it's fantastic."
BEST ANTI AGING SERUM 2024 - Which Botox In A Bottle Serum Wins
"For the formulation, I think this is worth every single penny. I love this because you're not just relying on that azelaic acid line like you are with the Ordinary product, you're getting that dose alongside so many other peptides, which for me is something pretty special. [...] If you don't mind spending a little bit more to get a little bit more, I think Medik8 still is the winner."
No1 SKIN FIRMING SERUM 2025 - 33% Firmer Skin FAST
"I love this product. It only launched about 4 months ago but I tried it and I was blown away. And I know from the comments that you guys have left so many of you guys have tried it too and been really impressed with the results. It's not just the ingredients that Medik8 use and formulate with. It's also the technology that they employ to make sure that the maximum amount of peptides and growth factors are getting to where they need to be in the skin to deliver that fantastic benefit."
BEST SKINCARE ROUTINE 2024 - Best Anti Aging Skincare
"The Medik8 Liquid Peptides is on the more luxury end, and it's amazing. It's encapsulated, so you can use it alongside your vitamin C without any issues. Other peptides which aren't encapsulated tend not to like lower pH environments like with vitamin C, so you have to be a little bit more careful."

"Pentipeptide 18 is present in the Medik8 Liquid Peptides Advanced, which is one of my personal favorite peptide serums and one that I actually use for its growth factors but also in the knowledge that I'm getting that extra pentipeptide action just to enhance the results I'm going to see from my line that's in my other products."
The End Of PEPTIDES SERUMS? - Products Are Vanishing (Heres Why)
"This is a phenomenal option that takes their original liquid peptides, which was a bestseller in its own right, and adds growth factors to the mix. Growth factors are phenomenal, another subset of peptides like copper peptides, but they're great because they're really driving forward that collagen and elastin production. They're relatively new in terms of skincare, certainly mass market skincare, and they're getting a lot of hype at the moment."
SKINCARE OF THE YEAR 2025 - Best Black Friday Skincare Sales Im Buying
"This one has those bio-engineered advanced growth factors, but with that 30% off, it's around I think I paid like £48 as opposed to the £180 that some other brands want. So this is a dupe [...] for those advanced options. [...] It's got a beautiful blend of 30% peptides and those growth factors alongside that. So it's a peptide serum and a growth factor serum all in one. I absolutely love it. I stocked up whilst it was in the sale because I know that I'm going to get through it."
NEXT LEVEL PEPTIDE SERUMS - Maximise Collagen In Skin
"This is the Medik8 Liquid Peptides. This contains a 30 peptide complex and multiple different peptides within it. You've got some for hydration, you've got some for evening out fine lines and wrinkles, and you've got some that can help fade hyperpigmentation. So this is a great one-stop shop option. Not the cheapest on the market, but again I think when you look at concentration and the types of peptides you're getting, this is a really really good option."
NEXT LEVEL PEPTIDE SERUM - The Strongest Botox In A Bottle
"This is an absolute star of a peptide serum. I think a lot of the hype online might be coming from sponsored voices, but take it from someone that's completely unsponsored and paid partnership free, I genuinely think this is amazing. I don't think I'm ever going to buy the original Liquid Peptides again, I think this has kind of superseded it, and for just a little bit more you get a whole lot more. I can see this being a permanent fixture in my skincare routine."
4x BETTER ANTI AGING (You Wont Believe The Results) - Medik8 Review
"Great product, 30% blend of different peptides, but they launched their advanced version recently, which actually I love so much I did cover in a separate video. [...] This takes that same formulation in the liquid peptides, and adds growth factors in. Now, the reason I think this is so phenomenal is the tech, the technology they use in here is like up here, next level, but the price isn't. So, the price of this if you use the discount code is £63. Now, that's not dirt cheap."

"So is it amazing? Yes. Will I be repurchasing it? No, but only because I found a cheaper alternative that personally works for me. If you're using and loving this, keep on at it, because it is a great formulation, but for me I just found that I could do it cheaper, and fundamentally I'm drugstore, and if I can get it cheaper why not."

"It also contains carnosine, which is great at preventing glycation in the skin, another precursor to aging, so it kind of works in two ways. I absolutely love it. I think Medik8 are doing some really wonderful things in terms of skincare, and their Liquid Peptides Advanced is one of the best growth factor serums you will find, at a much more accessible price point than some other ones. You can get the luxury without the luxury price point, if that makes sense."
Top 5 ANTI-AGING SKINCARE PRODUCTS 2023 - How To Boost Collagen Fast
"This is the Medik8 Liquid Peptides, a 30 peptide complex. A little bit boozier on the price point than maybe I would normally spend, but a little goes a long way and this acts as a hydrating serum and a peptide serum all in one. So yeah, definitely a really great option that packs a punch."
I Stopped Tretinoin - The Results Blew Me Away ( BEST ANTI AGING SERUMS )
"This is the advanced version of their original liquid peptides. This one has growth factors. These are the best bio compatible growth factors you're going to find in skincare at that price point. Medik8 is the next best thing and [...] it's about 70 pounds. So it's a lot less expensive and you get a lot for that because you're getting the growth factors, you're getting the peptides and you're getting something called carnosine."
Top 3 PEPTIDE SERUMS - Boost Collagen In Skin
"There are other patented delivery technologies, such as the neopeptide copper amino isolate, which has a similar one, but for me I just found the Medik8 one, based on my own skin's response, delivered the greatest benefit. Do you need a patented delivery mechanism in your peptide serum? Absolutely not. But if you do spend a little more to get one, I think you'll definitely see the benefits, particularly when it comes to the speed of the anti-aging."
SUPERCHARGED ANTI AGING - The Perfect Peptide Serum
"It's a 30% peptide concentration but with growth factors as a key component of that, and the growth factors in here are phenomenal, they're advanced in keeping with the one from Allies of Skin. It just genuinely delivers for you. It's a more affordable price point, and whilst I say the technology isn't quite as advanced as the Allies of Skin one, it's still going to pack a punch when it comes to results and does so at a more affordable price point. So definitely, definitely a win."
"I absolutely love it. In fact, I love Medik8. This liquid peptides advanced featured very prominently in that video because I think it's one of their best best products. Growth factors are fantastic because they boost collagen. They boost elastin. They work alongside your retinoids and your other firming and lifting ingredients like DMAE to really just help give you the maximum results. They also have some benefits around brightening the skin and who doesn't like a little glow up."

"You've got some pro-collagen peptides, some hydrating ones, a plethora of different peptides, just a true buffet of peptides to feed the skin and really improve overall skin health. Some great anti-aging. This is an amazing option if you don't mind paying a little bit more for your peptide serum. With this you're getting a lot more for the money that you're investing. Medik8, such a great brand."
Global BESTSELLING SKINCARE 2026 - Rating Most Purchased Skincare
"I find that Medik8 is the very best quality growth factors at the most affordable price point. It's not cheap, but when you compare it to say the Allies of Skin equivalent, which is three times the price, that's where I think it really does make growth factors of this quality that little bit more accessible and affordable. When you compare and contrast the quality versus the price, Medik8 wins because it's just that sweet spot that delivers."
Move Over Botox - 5 BEST ANTI AGING PEPTIDE SERUMS
"The Medik8 Liquid Peptides, the reason that I'm calling this out is you've got a 30% peptide complex in here, which is pretty high when it comes to peptide concentration, and I love that. After all, we're talking peptides, why would we not want the highest concentration you can get in order to give maximum results, and that's what you're getting in here."
ANTI AGING SHOWDOWN - Breakthrough Copper Peptide Serum
"So, this has copper peptides alongside other great beneficial anti-aging peptides. Phenomenal. Also has growth factors. And this is where you're kicking it up a notch even further. Whilst this might be roughly three times the price of the Mad About Skin one, you're getting that additionality of growth factors in here which I think really levels up the anti-aging experience, those growth factors are going to help promote collagen and elastin in a similar way that the copper peptides do."

"My personal favorite when you consider price point versus quality is the Medik8 Liquid Peptides Advanced. This is a peptide serum and a growth factor serum all in one. Even though it doesn't come with the cheapest price point, I see it as like a two-for-one, which makes things super easy and streamlines things, and you get your peptides alongside your growth factors in like the best multi-purpose serum."
$40 ANTI AGING BREAKTHROUGH - 4x Firmer Skin With This Miracle Trio
"I would personally recommend the Medik8 Liquid Peptides Advanced if you want skin-compatible bioengineered growth factors, which are the quickest acting and, some studies show, the most effective when it comes to anti-aging. [...] This is probably the most affordable of those bioengineered skin-compatible growth factors, since most others come with roughly two or three times the price point. [...] It's a great one if you want quicker wins and [...] the most advanced option."
Official: WORLDS No1 SKINCARE BRAND - This Brand Transformed My Skin
"This is the cheapest high quality bioengineered growth factor serum you will ever find. If you want that quality of growth factor but you don't want to pay the prices other brands charge, this is a great dupe, it's got all the peptides and it's a fantastic product. Growth factors are great for boosting collagen, elastin, and smoothing out the skin, and this is the best form of growth factors at the most affordable price."
Big COPPER PEPTIDE UPDATE - How To Use Copper Peptides In 2026
"This is the Medik8 Liquid Peptides Advanced. This is a fantastic multi-peptide serum that not only combines copper peptides but also growth factors. It's really like one and done when it comes to anti-aging. [...] When you consider everything you get with this serum, it's really not a bad price either. I use this on my neck because it's got growth factors, copper peptides, and other peptides all together, which has had such a difference on my neck."
SKINCARE DUO THAT TRANSFORMED ANTI AGING - 5 Years Later
"Medik8 have taken a very similar philosophy with their new Liquid Peptides Advanced. It combines the Matrixyl and Argireline peptides plus growth factors, and growth factors are fantastic at boosting collagen and elastin the way copper peptides are. So you're getting a much more comprehensive formula but still only requiring one product rather than the two you had in the original duo."

These are the ones that are already present in our body and so the skin recognizes them as a friend, welcomes them in and you get those super quick results."
"If you have super dry skin, they have a liquid peptide MP which contains a majority of those same peptides but has more of a lotion texture. It's also a little bit more expensive, and I'm not exactly sure why the price is higher on this one. It's [...] fragrance free as well. [...] This one's nice, it's got a lotiony texture and feels really nice and hydrating on your skin. You can use it morning or evening, whichever routine you prefer."

New Skincare Products Released- CeraVe Brightening Lotion, Prequel Retinal, PC, Medik8, Cosrx, FAB
"The Medik8 Liquid Peptides Advanced MP+ Serum, it's about 92 bucks, so it's expensive, but [...] it looks like it's just a fragrance-free moisturizer cream, but it's got some really great peptides that I haven't seen in a lot of products yet. So the basic peptides, we've got the matrixyl synthesis peptide, the synol peptide, the matrixyl 3000 peptide duo. Then we add some other ones that I don't see in a lot of stuff. We've got the toop pep 417, which is a collagen boosting peptide."

"If you check it out at Dermtore, usually there's a coupon, so it's worth doing some digging before you check out. This stuff's wonderful. It's a light serum, it helps firm and plump skin, and it's [...] got a gellish, serumy texture to it. [...] In here we've got really nice ingredients. I would say this one's nice for acne prone skin. It's got some probiotics in there, a couple of them, inulin. It's also got the carnosine peptide, which is an anti-glycation peptide."
"The Medik8 Liquid Peptides Advanced MP+ Serum is $66 and also contains panthenol, sodium hyaluronate, and carnosine peptide. It's one of my favorites, and if you're looking for overall peptides, one that contains a nice variety of good peptides, this is one of the three products I'd pick out, and it's easy to fit into your routine."
"This one is a glycerin, butylene glycol base, and they've added several peptides in here. I see [...] six or seven, and it looks like we've got the arginine peptide in there, which is nice. I thought I'd just put it on in this video because it came and I'm excited to try it out. It has no fragrance in it. This one is so light I think it'll take me a long time before I get through it."

The Ordinary Multi Peptide Serum with Copper Peptides Closest Dupes & Affordable Alternatives
"However, this one also has a really nice ingredient list. And I will say, you can notice it's clear, there's no color to it because it uses a special kind of copper peptide which does not turn things blue. For something to have copper peptides, it doesn't always turn blue because there's a type of peptide called copper palm oil hexapeptide 14, which is also known as the X50 anti-aging peptide duo."
Peter Thomas Roth Skincare Best Dupes & Alternatives to Their Most Popular Products
"The Medik8 Liquid Peptides Advanced MP+ Serum is really quite nice for the most part. It's [dimethicone] based and it's got matrixyl synthesis. It's got the crystallide peptide which is known for brightening skin up. It's got the sinol peptide, matrixel 3000, and the argolene botox in a bottle peptide. Fragrance-free, really nice. I would say more for dry or dehydrated skin types. If you have oilier skin, it might be a bit on the hydrating side."

"In terms of performance, it's a really nice serum, it instantly plumps up the skin. It feels so nice, my [...] hand is always kind of dry and wrinkly compared to the other one and it just instantly plumps it up, makes it look better, makes it feel better. It really helps with youthful skin. For what this product promises, a smooth skin texture, invisible signs of aging, skin that's left feeling smooth, firm and visibly supple, [...] I would agree it does pretty much all of that."

"I will say I haven't been enjoying this. I've got a couple of subscribers who didn't love this one, so keep that in mind. [...] I've been testing it for about a month now, since I ordered it [...] during the Black Friday sale. It's [...] fragrance free, and it does contain a small amount of tbutoal alcohol. For peptides, it's got the carnosine peptide, which isn't in a lot of things but you'll see it occasionally. It's a peptide that fights glycation, which is responsible for aging."

"I have a new one, the Medik8 Advanced Liquid Peptides MP that I have first tested in 2025 and that has become my absolute favorite with a great light lotiony texture. Peptides or copper peptides are not a must have in your routine. I want to incorporate them because I have everything else down to the perfect routine. At least for me, the perfect routine. So, I treat them as an add-on and I am willing to spend a little more on the texture that I'd like."

It has a lovely watery texture, unlike many more affordable copper peptide serums [...] I tested that were more lotiony, and it also contains mini proteins, which is an interesting area of research. Sadly it's incredibly expensive, but [...] I think I would repurchase this one."

"On non-Tretinoin nights I follow up with the Medik8 Advanced Liquid Peptides MP.

It's like [...] a nice bonus, not one of the main players, but I use that one."

"But still it has quickly become a favourite of mine. It has a beautiful lightweight texture that offers some hydration, less than a moisturiser, but enough to plump up the skin, which in combination with the Dimethicone will smoothen fine lines. The peptide complex used reads like the Who's Who of peptides targeting signs of aging, and both the drone delivery as well as the Dual Mini Peptides used are an interesting development."

"On non-Tretinoin nights I first use the Medik8 Liquid Peptides Advanced Wrinkle Reduction Serum. I don't use it first because of the peptides, but because it contains Growth Factors that are supposed to go on clean skin. I don't actively seek Growth Factors out, but as I was testing it anyway it for now has taken the place of my NIOD Copper Peptides. Medik8 isn't really hydrating, so I follow it with an extra layer for hydration."
"If you're looking for a growth factor serum, Medik8 Liquid Peptides Advanced MP+ Serum is my top pick. You get both the benefits of peptides and growth factors. I love the way this smooths my skin, absolutely gorgeous. Now, is it reversing deep wrinkles? Absolutely not. But for a growth factor serum, top pick for 2025."

"Another very easy to layer peptide serum was the Medik8 Liquid Peptides Advanced MP+ Serum. Super thin layer of this layers beautifully with any other skincare that I used. I would not combine these in the same routine. I think it's duplicating. Even though this has growth factors and a few more advanced ingredients, this is a great very intense hydrating peptide serum that will not necessarily firm your skin but deeply hydrate your skin and works well plays well with all other skincare."

"It's one of the best I've ever discovered for just a really good snatching and also plumping effect. It has amazing peptides to fight against premature aging, reduce inflammation, and excess puffiness, and it's like $60, which is still pretty expensive for what I usually recommend, but worlds better than $185. I feel like that would do even more for her skin than this one."

"It's one of my most recent introductions to my routine, but based off my research it's like the internet's best serum for anti-aging and plumping and softening the skin. Every time I use it I am blown away, and it's typically a little bit more pricey. If you want to find an incredible product for fighting and preventing premature aging, I would definitely recommend the Medik8 serum."
"You can also use a peptide at night. This is the Medik8 Liquid Peptides, and I would happily put that all over my face before putting on a retinol. You can easily use peptides, which are signaling ingredients, and they basically signal for the skin to repair itself as you sleep. You can wear them during the day as well. I just want something to give my skin slip to put the retinol or retinaldehyde over the top."
"If you're looking for something that is a little bit richer that has a little bit more advanced technology, the Medik8 Advanced Peptide Serum is also fantastic."

Answering Your Biggest Skincare Questions From The Comments Section | Dr. Sam Ellis
"The Medik8 Advanced Liquid Peptides [...] is one of the best peptide formulas on the market when it comes to anti-aging. Among the many amazing peptides that this formula contains, [...] it does have copper peptides, which you will see in a lot of peptide blends because copper peptides have some of the most robust data behind them when it comes to anti-aging benefits. However, copper peptides have the potential to be the most finicky out of all of the peptides that we use in anti-aging skincare."

"The Medik8 Liquid Peptides Advanced MP+ Serum was holy grail for me. I really think this year was the year for peptide innovation. [...] I think Medik8 was so thoughtful with this face serum, and it is just incredibly packed with the most evidence-based peptides when it comes to rejuvenating the skin. I really enjoy the texture of this product. It's sort of a thicker, milky serum, and I honestly think it could kind of double as a hydrating serum if you wanted to simplify your skincare routine."

"This has a mucin like texture. That's going to be gross for some people, but I love it. This is also quite hydrating, so I'm just doing a nice thin layer, bringing everything up under my eyes as well, and then drawing that down and around the neck. This is also another product that they've done their own clinicals on to show that it helps with fine lines and wrinkles."

"If you have a little more room in your budget and you want a more comprehensive peptide product, I really love the Medik8 Liquid Peptides Advanced MP+ Serum. This has 13 different peptides. It has Matrixyl 3000. It has the copper peptides, but some additional skin boosting peptides in there as well. Really nice lightweight texture. You can layer this before or after your retinoid in the evening. You could use it in the morning if it works better in your routine there. It's very versatile."

"The other serum that I've been using a ton this year is by Medik8, and it's their Liquid Peptides. Peptides are one of those things in skincare that often feel a bit vague because there are so many different types, but the reason I like this one from Medik8 is they've really taken the most proven peptides and incorporated them into one serum that, to me, is relatively affordable for how much goodness is packed into one product."

"If you're looking for something that is a little bit richer that has a little bit more advanced technology, the Medik8 Advanced Peptide Serum is also fantastic."
Dermatologist Explains How to Layer Products in Your Morning Skincare Routine | Dr. Sam Ellis
"This one is chocked full [...] of incredible peptides that have the most evidence for anti-aging collagen plumping benefits, so I think this is a really excellent product. This serum also has glycerin and hyaluronic acid, which are two very popular humectants that help draw water to the skin surface, so they're helping to plump the skin in addition to the peptides that are in here. So in my mind this is kind of like a two-in-one serum, a hyaluronic acid serum plus a peptide serum."
"This is the one that I think is absolutely superior to peptide serums out there. It's the Medik8 Liquid Peptides because this has a whopping dose of peptides in it. This has a 30% peptide complex. [...] This peptide serum has signal peptides in it, which are the peptides I look for. It's called Matrixyl 3000, it's actually a blend of two peptides. Signal peptides are the ones that are so well studied and have lots of evidence for building collagen in your skin."

"This is a great one by Medik8. It's really super lightweight and nourishing. This is a standout peptide serum option because it contains a 30% complex of peptides, which is a lot, and not just any type of peptides. It contains Matrixyl 3000, which is my favorite type of peptide from all of my research to build collagen in the skin. It contains acetyl hexapeptide-8, which is sometimes referred to as Botox in a bottle."
How I REALLY Feel About Aging Without Botox and Fillers
"The first thing I put on was a peptide serum. I [...] have several favorite peptide serums, and this is what I'm using right now: Medik8 Liquid Peptides. It's a 30% blend of the top three best anti-aging peptides in my opinion from my deep dive research: Matrixyl 3000, copper peptides, and acetyl hexapeptide-8. So that's what went on my skin first."

"In the mornings I'm pretty much only using my peptide serum. I've been bouncing around between a few different ones from a few different brands. Medik8 has one, so this is a newer one I've been trying lately in the mornings. I'll keep it either really simple, just supporting my skin barrier, or I'll use my peptide serum, and this is a really amazing peptide serum as well."
What the evidence says.
Independent of what the gurus think, this is what
the published research supports about the main active ingredients here.
Humectants and emollients
Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
Peptides are short protein fragments meant to signal repair. The evidence for them is thinner than for retinoids or vitamin C, and it varies a lot by the specific peptide, so the category is more promising than proven.
Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
