"It is Paula's Choice C15 booster serum now this is a vitamin C serum it is 15% active vitamin C you do not need more than 20% it also has ferulic acid in it to stabilize it"

"This one is $55 but it is just a serum and it is ascorbic acid, so this is for the ones who want the active form of vitamin C and just can't let it go. But it's not for everyone because it can be irritating, and you definitely do not need the 25% vitamin C. 15% is all you need."

"If you're somebody who just wants the most tried and true vitamin C, the purest form of vitamin C, you're talking about l-ascorbic acid, which is this one in Paula's Choice. You do not need to go higher than 20 percent. This comes in the form of a dropper. Unfortunately, once it turns really dark, it probably is not great and it can oxidize pretty fast."

"Paula's Choice is a 15 percent ascorbic acid with vitamin E and ferulic acid, though they do not specify the percentages of that. It still comes in a dropper, but it's a good option at $55 that provides the same active form with supporting ingredients as the more expensive alternatives."

"Paula's Choice just reformulated their C15 booster and increased the ferulic acid in it. It's worth checking out. It uses the amazing trifecta of ascorbic acid, vitamin E, and ferulic acid, which is the best and most effective way to help firm up skin."

The Best Vitamin C Serum Alternatives to the $185 Skinceuticals C E + Ferulic Serum

"Paula's Choice C15 Super Booster uses [...] 15% ascorbic acid, vitamin E, and ferulic acid. It also includes a peptide as well for anti-aging. It's more expensive than all the other ones so far, but a lot of people like it and have good luck with it. But I will mention it's 55 bucks and it's not comparable in terms of size. This is [...] 20 milliliters. So it's two-thirds the size of the other ones. So when you're thinking about numbers, keep that in mind because if this were an ounce, this would be 70 bucks, something like that, maybe a little bit more."

"Paula's Choice C15 Super Booster for brightening is basically a vitamin C serum and this one is currently $55 for [...] 20 milliliters, which is a lot of money for vitamin C serum. I don't remember this one being this expensive however it's 55 bucks."

Best & Worst Vitamin C Serums of 2023

"The Paula's Choice C15 Super Booster, it's pretty expensive, that's why I don't recommend it in my favorite ones, but it's expensive and it comes in a really small bottle, two-thirds of an ounce, and it's really expensive, but I've still typically had good luck and good results with it."

"They've updated the formula to include more ferulic acid, and it contains fifteen percent ascorbic acid and vitamin E, so it's got the ascorbic acid, ferulic acid, vitamin E trifecta, plus bisabolol for soothing, and it's fragrance-free. It's fifty-nine dollars, which is on the pricier side. Paula's Choice was one of the first vitamin C serums I really tested and it was really quite nice. I can't say anything bad about it other than it's still more expensive than the Geek and Gorgeous."

"They've also gone for a stable glucoside, so that's working the epidermis more. It's naive safe, no denatured alcohol, no fragrance, no essential oils. And there are other antioxidants in this product, which is brilliant. It's an airless pump. Brilliant. And it's got glycerin in it, too. So, a humectant. So, it's done a lot right. I think the only downside for me probably is the high price point. So, it's £61 for 30 mls. But, if you can afford it, it's a wonderful, wonderful vitamin C. Definitely doctor approved."

"The Paula's Choice one is a really great analog of the SkinCeuticals vitamin C, and it's a lot less expensive, but it does oxidize pretty quickly. If you're looking for a vitamin C that doesn't oxidize that's probably going to give you very similar results, look for something with ethylated ascorbic acid. It's an ethylated form of vitamin C which cleaves that ethyl group once it enters into the skin and it's more stable, absorbs easier into the skin and it will have a much longer shelf life."

Is Vitamin C Worth The HYPE?? | Doctorly Investigates

"I'm a big fan of Paula's Choice just in general. I think that they make overall good products. [...] This is a product that I've recommended for a really long time. It's 15% vitamin C, vitamin E, and ferulic acid, and fragrance free. It's very similar to the Skinceuticals formulation, but [...] the interesting thing about this one is that they've actually recently reformulated it to decrease the irritation from the product. A lot of people do experience irritation with the formula, so they added arginine to the formula to make it less irritating. I've tried it on myself and I actually find this version to be much more tolerable than other forms of pure L-ascorbic acid. [...] I love the texture too, a nice full body, a little thicker serum."

"The Paula's Choice C15 Super Booster is 15% ascorbic acid in a stabilized formula. It's definitely going to be more expensive than the previous options we've talked about, but it's a very good vitamin C, and they've done some great demonstrations through social media showing its antioxidant power."

"Paula's Choice C15 Super Booster is 15% L-ascorbic acid, ferulic acid, and ergothionine, which is an amino acid that is commonly found in mushrooms and black beans and works as an antioxidant. This one is really well formulated and backed by science. I find that it's a very light hydrating serum. It's been another staple of mine that I've been really enjoying and that I recommend a lot to my family, friends, and my patients."

"I really enjoy the Paula's Choice C15 Super Booster. There's a lot of vitamin C serums that I love that I still use but when it comes to these types of vitamin C's they are very unstable and they oxidize very quickly because this is the purest form of vitamin C, L ascorbic acid or ascorbic acid."

"I do like the Paula's Choice one very similar to the Timeless but again we have that 20 mil size. This one is fragrance free it does have a little bit of that smoky scent from what I can remember it's been a while since I've used this one, and there's a 4 month shelf life with this one."

"The C15 Super Booster is a holy grail from Paula's Choice because it is a stable form of vitamin C, L ascorbic acid, and it has vitamin E and ferulic acid in it as well. It's a great product at a fraction of the price of the SkinCeuticals one. I like to use vitamin C in the morning skincare routine to help build new collagen, to help lighten dark spots and fade hyperpigmentation, and just brighten and tone the skin. It's an antioxidant so you are fighting free radical damage on the face from UV light."

Top Pick: stable vitamin c serum

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Vitamin C

Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Source: DermNet

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.

Source: DermNet

Peptides

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.
