Lucent-C Brightening Vitamin C Serum.

"I get why she chose L-ascorbic acid at 15%, it's very similar to the $180 SkinCeuticals in terms of formula, with vitamin C and ferulic acid, and it even smells like the SkinCeuticals, like meaty water. But I just don't like it, it's runny, it will oxidize in time, and it's got a real heavy sticky feeling that doesn't fully absorb. It also has to be at a pH of 3.2, which is a bit low, so if you're reactive it can sting. I absolutely prefer the Remedy Skin vitamin C, even though its ingredients don't have the level of research that L-ascorbic acid does, because I just can't do L-ascorbic acid, it's stinky and it stings my skin."

"I hadn't yet gotten around to trying the Lucent Sea Brightening Vitamin C serum from Prequel. I didn't have time to check the ingredients, so I just pumped some out and smacked it on my face. Standing there looking in my bathroom mirror, I realized I had made a terrible mistake, because my poor dentist was going to have to smell that smell while working on my teeth right after. It would have taken me two seconds to read the bottle first."

"It punches well above its price point. For context, this is often compared to Skinceuticals C.E. Ferulic, which retails for around $180. The Prequel Lucent-C offers very similar core antioxidant benefits for around $23. That's a really big difference. And in my experience, it layers beautifully into your daily routine without feeling heavy or sticky. It doesn't cause irritation for most people. For mature skin dealing with sun damage, dark spots, loss of radiance, this is one of those best affordable options out there. Personally, I also love that it comes in a pump. And it doesn't smell like hot dog water like the expensive version of it. The key ingredient here is the 15% ascorbic acid, ferulic acid, and niacinamide."

"The Prequel Lucent C Vitamin C serum, which is 15% L-ascorbic acid, provides really potent brightening effects, antioxidant protection, at a really affordable price. [...] It can help minimize the appearance of dark spots, boost your skin's natural radiance, improve overall skin tone. I think it's suitable for daily use. It's more suitable for like your normal to combination oily skin type. If your skin is really, really sensitive or super duper dry, this one can be a little spicy because it is the original L-ascorbic acid. [...] It's a very affordable option. The key ingredient is L-ascorbic acid 15%. Also contains ferulic acid and niacinamide."

"This is the Prequel Lucent-C Brightening Vitamin C Serum, and it's 15%. That's pretty high strength vitamin C serum. It's designed to visibly brighten dull skin, improve that uneven skin tone, support a firmer looking complexion. I love this option for mature skin that's specifically focused on brightening and addressing early signs of photoaging. Vitamin C makes it in my top three non-negotiables for skincare in your 30s. And I do think introducing in your 30s and then just adding to it as we mature is beneficial. This particular vitamin C formula is best suited for those who already tolerate vitamin C well and they want more noticeable brightening effect. The key ingredient here is the [L-ascorbic] acid which can be somewhat irritating on really really sensitive skin but I would say that most of my patients tolerate it really well. The other ingredients are [ferulic] acid and niacinamide."

"I tend to alternate this last time you saw me using Prequel Lucent-C Vitamin C and I love it. [...] If you have really dry skin [...] or a budget friendly option might be Prequel's Lucency. The key ingredients in this one are 2% flutin, it's derived from apples and the bark of fruit trees like pear and grapefruit. The flutin helps neutralize damaging free radicals, aids in cell turnover and improves the appearance of discoloration. This also has 10% pure vitamin C, which is L-ascorbic acid. This is a very potent antioxidant. It protects against oxidative stress, brightens the skin, provides visible anti-aging benefits."

"The first one is the Prequel Lucent-C Vitamin C Serum. 15%. It helps brighten, firm, hydrate. It will support that skin barrier. It's clinically shown to boost the radiance and reduce dullness in just like 4 weeks. It will help improve some of the brightness and firmness and elasticity. And the Prequel Vitamin C is really, really lightweight. So, I would apply my Prequel Vitamin C prior to applying hyaluronic acid serum."

"It delivers the same brightening antioxidant protection with the same concentration of 50% of the same active aloscorbic acid. It is clinically proven to increase radiance and luminance after 4 weeks."

"It will help reduce dark spots, boost skin's natural radiance, improve that overall tone. It's suitable for daily use, and it enhances that natural glow, helps improve brightness and firmness. It also hydrates a little bit, and it's clinically proven to increase the radiance and luminance after 4 weeks. The key ingredient here is the L-ascorbic acid. It is 15%. It also has niacinamide and ferulic acid. I love the dispenser. I'm a total sucker for packaging here. The Prequel Lucent-C comes in a really nice pump dispenser and I use about one and a half pumps and I just pump it into my palm and then apply it to my face and I can rub it in. It does not smell. If your skin is very sensitive or if you've overused your retinoid, it can cause some irritation. So, if you're very sensitive, this one you may want to be careful with."

"My favorite product recommendation in this category is Prequel Lucent-C Brightening Vitamin C Serum. I am obsessed with this product, it's such a steal in comparison to some of the other vitamin C's on the market. The serum provides potent brightening effects and antioxidant protection at an accessible price point. It reduces dark spots, boosts skin's natural radiance, and improves overall tone. It's suitable for daily use and enhances skin's natural glow over time. Some of the key ingredients here are things like ascorbic acid or vitamin C, which is a potent antioxidant for skin brightening, it also contains ferulic acid which boosts the stability and efficacy of vitamin C, and niacinamide which helps even skin tone and reduce redness."

"My recommendation in this category is definitely Prequel's Lucent-C vitamin C serum 15%. It provides really potent brightening effects and antioxidant protection at a really affordable price. It is probably by now available at your local Target as well. It can help reduce dark spots, boost skin's natural radiance, and improve overall tone. It's suitable for daily use for most skin types. Now, some skin is sensitive to L-ascorbic acid, which is the active ingredient here, but most people are going to do just fine with it. The active ingredient again is the L-ascorbic acid or the vitamin C at 15%. It does have ferulic acid and a little bit of niacinamide in it. Now, niacinamide is another really cool ingredient. It's also called vitamin B3 and it is incredibly versatile. It helps inhibit some of the melanosome transfer. So basically, it blocks pigment from spreading to the skin. It can help strengthen your skin's natural barrier by increasing ceramide production, but it can also help reduce inflammation, which is great for acne and redness and regulate oil production."

"The first one is the Prequel Lucent-C and you guys know I'm a big fan. This is 15% L-ascorbic acid and ferulic acid. It is very similar to the OG Skinceuticals vitamin C. I don't believe in dupes so I wouldn't say that it is the same, but I think that if you're looking for something that has good ingredients, good data, and you want the feel of Skinceuticals vitamin C, the C E Ferulic, not the Flutin CF, this is your girl. Pretty affordable. I love the packaging. I like the dark container. It's heavy, good stuff."

"I did recently finish the bottle of lucency from prequel. I loved it. It's very similar to skin sudicles. It does come in a pump which I much prefer over the dropper bottle."

"I'm going to plug my friend Dr. Sam Ellis and her brand Prequel. I think that her vitamin C serum is fantastic and it's essentially the Skin Suiticles but like updated."

"It's a great vitamin C serum in my opinion, very comparable to the Skinceuticals C E Ferulic, but I also think this one's a little bit better because it's just a much better price. It has 15% ascorbic acid in it, it also has ferulic acid, so you get a little bit of that smell, but it's nowhere near as intense as the Skinceuticals one. It's very faint and it dissipates pretty quickly. Instead of vitamin E there's a different antioxidant that helps to not only keep the ascorbic acid more stable but it also helps your skin by providing more antioxidant benefits to it. There's niacinamide in here, there are so many other really nice ingredients in this serum. I just think it's great if you're looking for a traditional vitamin C serum. That said, it is at that lower pH level, so if you've experienced other classic traditional vitamin C serums and they irritated your skin, there's a chance that this one will, but it's such a good price, it's so affordable that it's always worth trying out."

"When you use antioxidants in your skincare routine it can be very helpful in conjunction with your sunscreen, and that's because UV rays also throw off a lot of free radicals so you can get free radical damage. When you're combining a vitamin C serum like this one from Prequel with the use of your sunscreen, you're just getting much more benefit and protection from UV radiation. Vitamin C has just been shown to be really effective when combined with your sunscreen and protecting your skin from free radical damage."

"Vitamin E, ferulic acid, and ascorbic acid, that's the trifecta that's what you want to see. Those three ingredients together make the vitamin C serum work so well. I like it, it's fresh, it feels nice, it doesn't feel greasy."

"Their vitamin C serum is great. It feels really nice on the skin, which is hard to accomplish."

"Prequel, and this one is 20 bucks so it's still pretty affordable, it's their Lucent-C vitamin C serum. This one contains, again, 15% ascorbic acid, then it's got ferulic acid and it's got inulin in it as well, and it's really nice. They sell it everywhere, this brand is getting very popular now, they have their own website, they're at Target, I think they're on Amazon. I start to get concerned when they're starting to sell so many places, how that stock lasts, how long it's been there, that's when I start to get nervous. Once a brand becomes so big so quickly like this brand has, and has released so many products recently, I start to worry that if you're at your local Target that stock could be four months old, five months old, I don't know. So that's when I start to get a little nervous. You might be better off buying from the website, I'm not sure, it just depends on how they manage it. But overall this is a nice formula, it's a nice serum, so it's worth checking out, still pretty affordable."

"Their Lucent-C serum is great."

"The Prequel Lucent-C Brightening Vitamin C Serum is 15% L-ascorbic acid with ferulic acid and ergothioneine. The pH is 3.2, plus or minus. [...] I started using this every day, going in full force. You use [...] a few pumps on face and neck before all the other stuff and finish with sunscreen. [...] I did it every single morning."

"I'd gone through at least like two bottles of this. I [...] love it. I really do. I like it a lot. [...] I did experience a purge with this when I first used it, [...] but if you just stick with it, you get through to the other side and you look fabulous. I'm back on it and things have been going well. [...] I like that it's nice and lightweight, but there's still like a little bit of a silk to it, so it adds like a little bit of moisture. Today I'm not really wearing a ton of makeup, but all I'm wearing for my base is this and some sunscreen."

"The Prequel Vitamin C has a great price point. I love the formulation. Just reading about the ingredients and how it's created, I think this is a standout product. It's [...] the number one most recommended vitamin C in the comment section. [...] If you're in the US and you can get your hands on this, I would think it's worth giving it a go just based on the results that people have said."

"Prequel, really love it. [...] They have vitamin C, probably the best of their products. I would totally recommend."

"The Prequel Lucent-C Brightening Vitamin C Serum is derived mainly from mushrooms and on studies on skin cells in the lab it looks like it can do some of the same things that vitamin E can do such as regenerate vitamin C. This formula also contains niacinamide so you're definitely going to get a brightening of your skin with this. The Prequel vitamin C is much more of a watery liquid, will run through your fingers but you just squeeze them together tight. It does absorb really really quickly and this doesn't really leave any kind of a tack or stickiness on the surface of your skin so it rubs right in."

"The first one is from Prequel and this is a 15% ascorbic acid vitamin C serum. This is really nice and lightweight. The price point is pretty comparable to the Timeless. The main difference is that the Prequel is a 15% vitamin C and the Timeless is 20% vitamin C but they're both formulated at the right pH and they're very, very nice products, very lightweight and watery."

"The prequel one turned brown really really fast so I was a little disappointed in that. Ascorbic acid based vitamin C serums have to be formulated right, they have to be in the right packaging in order for the vitamin C not to oxidize, but when it oxidizes it turns brown, and once your serum is brown it's really no good and you shouldn't use it."

"I just discovered this one last month. This is from Prequel, this is a dermatologist brand. This is a 15% ascorbic acid vitamin C serum. This one is $23 an ounce. I think so great price point on both of these and they will definitely help your skin to produce more collagen."

"Even though I love it and it is the vitamin C that I use day-to-day, we're not a global bestseller yet, so we're not talking about it in this video."

"My absolute favorite affordable vitamin C is from my brand Prequel and it's called Lucent-C. I truly have not seen a better, more effective vitamin C at this price point. I consider myself a true connoisseur of vitamin C, so if I was going to make or formulate a vitamin C product, I knew it had to be exceptional. It not only had to include evidence-based ingredients but also be effective as well as a joy to use, and to me that is what the Prequel Lucent-C really is. It has 15% L-ascorbic acid, which is the studied strength of L-ascorbic acid that has been proven to be the most effective. It also has ferulic acid and something called ergothioneine, which helps prevent the vitamin C from oxidizing and keeps it in its most effective form for longer. I like this serum because it's creamy. It's formulated with ceramides and so it feels a little bit more moisturizing and rich than your average antioxidant serum."

"Prequel's vitamin C serum is more of an evolution of the Skinceuticals C E Ferulic because instead of having vitamin E, it has a different antioxidant called erathionine. It was still formulated with the same goals of giving brighter, healthier skin and it's under $25."

"If you want a drugstore option that also uses 15% L-ascorbic acid, 15% vitamin C, may I recommend the Prequel Lucent-C. This is my skincare brand, but I knew when I created a skincare brand, I wanted to create an effective vitamin C serum that was really affordable. So, this is an option for you if you are within the US."

"The vitamin C I'm using today is by my brand Prequel, it's called Lucent-C. There are many benefits to topical vitamin C, one being a protection factor, so it protects you against free radical damage. As your skin is assaulted during the day, these little oxygen-free radicals form in the skin and they can bump around on important structures in your skin and prematurely break them down, so vitamin C guards against that. [...] Aside from the protective abilities of vitamin C, it also has these other benefits like brightening the skin, helping with hyperpigmentation, also helping support collagen synthesis. Anything that's going to help us make new collagen, make new structural support proteins in the skin, is going to help with anti-aging."

"Lucent-C is the vitamin C that I have used all year long. I'm [...] a huge stickler when it comes to vitamin C: I want it to have good strong actives, I want it to be gentle on the skin, and I wanted it to be science backed. [...] This has 15% L-ascorbic acid, which is the most studied form of vitamin C. [...] The whole point of this is to fight off oxygen-free radicals, those little damaging molecules that happen over the course of the day from external factors like UV radiation and pollution as well as your normal skin cellular metabolism. [...] Having an antioxidant in your skincare routine that consistently protects your skin is going to help with things like premature skin aging. Vitamin C is also known for helping with clarity of the skin, brightening of the skin, reduction of brown spots as well as producing collagen, which is going to make your skin less wrinkly, more plump, and just more radiant. In addition to having the 15% vitamin C, this also has something called ergothioneine, which is another type of antioxidant."

"When I created my brand Prequel, I knew I would want to offer an affordable vitamin C if I felt like we could do a really really good job with it, and I kind of feel like we hit our Lucent-C out of the park. I am obsessed, this is the only vitamin C I use now."

"This product is gentle and allows it to be used in a wider variety of skin types that may not be able to tolerate other ascorbic acid formulations. It has absolutely fantastic ingredients and is just so beautiful from a textural standpoint. I look forward to putting it on my skin every day. One issue when you formulate with ascorbic acid [...] is that it can sometimes feel sticky or a little bit tacky on the skin, but there is none of that in this formula. It is waterweight, it is slippy and hydrating when you put it on the skin, it spreads effortlessly and then it dries down quickly without any stickiness or residue. [...] The fact that this is a pump means I don't have to worry about throwing it in my bag or having it out on my vanity, which makes it that much more easy to use and helps me keep my product safe. [...] When it dries down you just get this instant luminosity to the skin. [...] This is fragrance-free and allergy tested and it's been pH optimized. The pH of this is between 3 and 3.5, which is the perfect pH to maintain vitamin C's efficacy but also reduce any irritation that people might get from other vitamin C products. The ingredients are incredible, the formula feels so good on the skin, and I think one of the most incredible parts about this product is the price point. I am a vitamin C snob and [...] have tried so many out there. I've personally paid over $150 for a bottle of vitamin C because I was willing to do that for a great antioxidant product, but now I have this and it is $23."

"The reason I love the Prequel Lucent-C Brightening Vitamin C Serum is because it has 15% L-ascorbic acid as well as ferulic acid and another antioxidant called ergothioneine that helps stabilize the vitamin C within that formula. Not only does this make for a super effective product, but it also makes it a bit more tolerable, so for people who have sensitive skin and are interested in trying a very effective vitamin C, this is a great option. In my experience as a dermatologist, I've noticed that a lot of topical antioxidants are really expensive, so I wanted to make a product that was affordable and accessible. If you already use vitamin C and you understand the benefits that it can have on your skin, incorporating this into your routine will be amazing. If you've thought about incorporating a topical antioxidant but you've been intimidated because you're worried that it's going to cause irritation or it was out of your budget, this is a great option for you as well."

"With so many L-ascorbic acid products out there, they can be incredibly expensive and people don't want to make that leap into trying an expensive product just to find out that it irritates their skin. Because this product is $23, even if you have not gotten along with L-ascorbic acid in the past, it allows someone to try it and then if they aren't able to tolerate it, they can use it up on their neck or their chest or their hands and not feel like it's been a total waste. This is one of our most popular and beloved products and since launching it, I have gotten so many messages on Instagram and also on YouTube from people who have classically had sensitive skin and not been able to tolerate L-ascorbic acid saying that this product really works for them."

"When I made an antioxidant for my brand Prequel I also wanted to use [L-ascorbic] acid and that's what's in our Lucent-C serum."
