Interface.

"If you're looking for a cheaper alternative then the stratia interface is finally back in stock love this serum it was out of stock for the longest time it's back and it's a great affordable growth factor serum"

"One of my favorites comes from Stratia, which is their Interface moisturizer. Unfortunately this is currently sold out. I spoke to Stratia and they said that we're going to be bringing this back at some point early 2024, so watch this space. But this also contains growth factors in a more moisturizer format. The Allies of Skin is definitely a serum, this is more of a moisturizer, a cream base. Great affordable option, hasn't quite got the technology that you get with the Allies of Skin, one does contain those growth factors in a good concentration. Out of stock but want to keep your eye on. I'm definitely one I'm thinking as I come into 2024, I might be persuaded to maybe use the Allies of Skin one on a morning and use the Stratia Interface on an evening or vice versa to kind of stretch this product, save some coin. When that comes back in stock I would be tempted to potentially do that. It's kind of worth the wait."

"For the absolute budget friendly option for people that don't want to have to splurge when it comes to that peptide and growth factor combo, you could always reach for the Stratia Interface. [...] It's an amazing option with growth factors and peptides together. This comes at a fraction of the cost of other recommendations, but just know that the type of growth factors used in this isn't quite as advanced as either of the other two. So you are compromising slightly, but for that price point, honestly, I think this is wonderful."

"If you're using a peptide primarily for firming and tightening the skin then the best hands down goes to Stratia and their Interface serum. This uses a potent blend of peptides alongside growth factors which are going to give you that maximum lift and tightening result. Peptides are phenomenal when it comes to anti-aging boosting collagen and elastin but combining with growth factors is like the best way of getting maximum results. So if you're in the market for a peptide which is going to deliver that maximum firming and lifting, Stratia Interface is the best one."

"The Stratia Interface is [...] an absolute phenomenal product that [...] has peptides and growth factors together in a serum, so it's like a two-in-one. The type of peptides they use [...] aren't as bioavailable in terms of compatibility with the skin's own growth factors as with other higher priced options, so you're going to have to have a little bit more patience. [...] They use plant derived growth factors, but honestly, that's fine. I've got some great results with plant derived growth factors. I think you just have to set your expectations, be a little bit more patient and keep with that consistency to see those results. If you can do that, you'll get some phenomenal outcomes when it comes to anti-aging. [...] For the price point, which is super affordable, Stratia have put everything they can into this serum. You've got the anti-aging peptides, you've got the pro collagen growth factors, you've got a blend of hydrating and plumping ingredients. It's just such a nice product. Because it has a hybrid cream to serum texture, I [...] use this as my moisturizer and serum in one since I have oily skin. If you have dryness prone skin type, you're going to want to treat this as a serum and put a moisturizer on top. But if you're oil slick morning through till evening, this is your moisturizer and your serum all in one."

"If this isn't within your price point, another really great option is the Stratia Interface, which [...] you would use in the same point in the skincare routine, you just swap the two out. I think the other is slightly more high potency, but the Stratia one is a lot cheaper, so there's something here for everyone. Don't feel that you have to miss out on growth factors just because you can't splurge. That Stratia one actually is really, really nice. I usually put one and a half pumps and that will do all of my face and I'll take it down onto the neck too. Growth factors are great for boosting collagen and elastin."

"I think having experimented with a lot of neck creams, I genuinely think the one that's had the biggest difference on my neck is the Stratia Interface. It's not even a neck cream, but I just used it on the neck where I get tech neck because I'm looking down a lot, and it really worked. I've tried lots of bougie expensive neck creams, and I think the Stratia Interface hands down has worked better than all of them."

"If you're looking for those growth factors on a slightly more affordable price point you could always opt for the Stratia Interface serum. This is one that I've used very regularly over the years and always always gone back to because again it just works. This gives you that dose of growth factors which is present in the Allies of Skin one but a much lower price point. The difference here is you're going to have to persevere a little bit more for the results so the potency isn't quite as high with the Stratia one versus the Allies of Skin but it's a fraction of the price point. So I'd say maybe wait 12 weeks to start seeing the results with Stratia and those results appear a little bit more gradually so definitely need to be in the long haul but it's just proof that if you're on a budget you don't have to compromise you just have to have a little bit more patience. This is a really nice product I love the blend of different peptides again with a great amount of growth factors this super affordable and Stratia one of my absolute favorite favorite products."

"This will actually replace your peptide serum and your growth factor serum if you have both of them in your skincare routine. This is a two-in-one. If you're someone that doesn't currently use growth factors but you're interested in incorporating them, just swap out your peptide serum for this. It means you don't have to have an extra step but you're going to get a whole lot of additional benefit. For me this is 10 out of 10 performance. The great thing about Stratia is they now ship internationally. Two years ago when I also declared this to be the world's best serum, they only shipped to the US and Canada. They're now international. I've got a friend on the Isle of Man, off the coast of the UK, which gets this delivered to them, so they literally ship to every island and location in the world. They're also entirely vegan, so if you're vegan or living a plant-based lifestyle you don't need to miss out on your collagen boosting. You can get this which is going to give you those growth factors, peptides, and all of that without animal-derived ingredients. They're cruelty-free. This as a brand is art perfection, and this I'd say is the best of the best when it comes to their products. I've used this on and off for the past two years and my skin loves it. I only realize just how much benefit it brings when I stop using it. When it's been out of stock or I've forgotten to put an order in, I stop using it and my skin says, what are we doing, what are we missing?"

"I would say reach for the Stratia Interface serum. This is a really really nice serum that contains peptides alongside growth factors. And whilst it might not have the same technology which the Allies of Skin one does, it comes at a fraction of the price. In the long term, you're still going to get some next level results as long as you're consistent with it. Stratia definitely this is my favorite product from the whole collection and they were one of the first brands to really do affordable growth factors and for that they'll always have a place in my heart."

"The reason that Stratia wins when it comes to formulation is because you've got so much else going on alongside it. You've got panthenol to calm and soothe, you've got other hydrators and humectants which are going to plump out the skin, you've got other beneficial hyperpigmentation ingredients such as licorice root alongside the peptides, the growth factors and everything going on for just roughly £5 more. You're basically getting a three-in-one serum with the Stratia, which is why for me it wins on formulation every single time. An absolute stunning, stunning product that, yeah, for me I've always always been impressed with how they managed to deliver all of that for that price point. It has the most beautiful sort of half serum, half cream texture. It's not a thick cream like a moisturizer, but it's also much more creamy than the standard serum. This I actually really like because for us oily folk like me, you can kind of use this as your moisturizer, it's that hydrating. For people that have a more dryness-prone skin type, you're probably going to want to use this and then top it off with a moisturizer, but you'll certainly enjoy the additional hydration that it gives. That serum-cream hybrid is fairly unique and honestly I found it super, super enjoyable."

"Stratia are an amazing brand they're known for their next level formulations and their affordable price point. This comes in at about $28 which is super budget friendly. When you look at the formulation you're getting a sensational blend of different growth factors alongside great peptides and some other great hydrating and plumping ingredients too. This is an all around Holy Grail and I think for the price point honestly this formulation is 10 out of 10. I've recommended this serum on the channel so much in the past and I stand by that. I think it's a great allrounder. I absolutely love this. I can't sing its praises enough. I think for me it's the best allrounder on the market. You're still going to have to use it consistently twice a day for a couple of months before you'll see those tightening and lifting results but trust me they will come. This is beautiful. It's also super easy to use because it comes in a pump which I personally really enjoy. Easy to dispense. One pump will do the whole face. You might want to use another pump for the neck and the top of the chest. You've got that peptide hit. You've got a blend of different growth factors and for me this is so so phenomenal when you look at that price point. Honestly I paid double for what you're getting in terms of this product."

"If you can't afford it, you could use the Stratia Interface. That's a really nice option."

"The Stratia Interface is a great option if you're looking for growth factors on a budget. It's the same rich velvety cream-like serum hybrid, it's got those growth factors, additional peptides, it's kind of doing everything. I don't think I've skipped a day when it comes to my growth factors for the past 6 months and I don't plan on anytime soon, but I might switch it up to a more affordable option and the Stratia Interface is perfect for that. I'm probably going to take this through for the next 6 months for a bit of a more budget-friendly growth factors option."

"Stratia Interface is a growth factors serum which I think is quite advanced. [...] For me it just works. I'll tend to put two pumps and that'll do the whole face and the neck. [...] I do definitely notice that I've got some lifting and I've got some great anti-aging from including growth factors. I think growth factors are one of the most potent when it comes to anti-aging."

"If your budget doesn't stretch to this then you can absolutely use the Stratia Interface serum as an alternative not quite as technologically advanced but it's still got that growth factors a fraction of the cost and gives you a good option for those of us on a budget. If your budget doesn't stretch to it have a little patience use the Stratia and it will definitely definitely pay off."

"If you've got a drier skin type treat this as a serum and use a moisturizer on top. If like me you're super oily this is going to be moisturizing enough so this would replace your existing moisturizer. What you're getting is a beautiful blend of different anti-aging peptides and growth factors which are one of the best ingredients for tightening and lifting the skin. I think the blend of peptides and growth factors in this is honestly unparalleled for the price that they're asking. Phenomenal price point, great formulation, Stratia just a wonderful brand. Also great if you're vegan or living a plant-based lifestyle, Stratia products are vegan."

"I absolutely love the Stratia Interface. This is an incredible, not too expensive peptide cream. It proves that you don't need to spend a lot on a good peptide product. I bought another one."

"Interface is Stratia's new peptide moisturizer, and I'm quite a fan of peptides. It has repairing peptides in it and it's more of a midweight moisturizer. Mixed with Lipid Gold's ceramide lipid rich formula it covers all my bases, to the point that I really may not need a serum if I use them together."

"I have fallen in love with the egg, because it's using two of my favorite products, not just from Stratia but my favorite products of all time, the Interface moisturizer and Lipid Gold. On their own these are incredible products, together I feel like you really do get the best of both worlds."

"I absolutely love this, unsurprisingly, because I do really well with peptide ingredients. The only thing I don't like about it is that I don't know when I'm running low, so before I recycle the tube I'm going to weigh it to try to get an estimate. I did repurchase the upgraded version of this one."
