"It's one of the newer launches that I tried, and my skin really likes it. I've probably used it maybe for about 2-3 weeks now. What I like about it is that it goes beyond just brightening, it also helps target uneven tone and discoloration. It has really nice texture, it layers really easy under your sunscreen, and it's easy to consistently use it in the morning."

"It's got niacinamide, which is a great brightening ingredient. It's got ascorbic acid, tranexamic acid, it's got acetyl glucosamine, which is a great brightening ingredient. Then it's also got ethyl ascorbic acid. So it's got three different vitamin C forms, which are all great for brightening skin. I really love this formula. It feels really nice and elegant under my makeup and sunscreen."

"Spreads very easily, which is nice. A little bit seems to go a long way. No scent in this one, either. Feels nice on my skin. So far, a nice vitamin C serum, this one seems to deliver. It doesn't leave my skin looking too greasy or anything. [...] For vitamin C, we've got tetrahexyldecyl ascorbate, niacinamide, and ethyl ascorbic acid. And then for some of the brightening ingredients, we have tranexamic acid, ferulic, several peptides, which are always a selling point to me. I love the peptides."

"This one's got resorcin in there, [ascorbic] acid, tranexamic acid, ferulic acid. It's got a lot of nice brightening ingredients if you're willing to take the chance with this company. Or maybe order it from Sephora where you could return it more easily. I [...] do like the product. I've liked the brand, but when you hear bad things about customer service, it doesn't make me want to recommend them."

"Those three should help brighten your skin up and protect it. So this would be a great daytime serum underneath sunscreen. It's also got some brightening ingredient tranexamic acid, ferulic acid, centella, and then it's also got Snap 8 peptide, which I personally am a huge fan of. And then it's got glutathione for brightening skin. So this is something that's definitely on my radar. [...] This one's got a little bit of everything that I love in it."

"Since I have been trying this product out, I have not gotten any irritation on my skin. No increased redness, no burning or stinging throughout the day or with other skincare products, which can be so common when you're using pure [L-ascorbic] acid active vitamin C serums. [...] The three types of vitamin C in this 15% complex are [L-ascorbic] acid, 30 ethylcorbate, and THD ascorbate. [...] I like that this is an airless pump, so no dropper bottle format."

"I was actually using this prior to the launch and I've been using this for several several weeks and I'm actually almost done this and I'm going to be buying another one because I really really like it. And if you have any post acne marks, this does help to fade those areas quite quickly when you are consistent. And when I had the post acne marks, I was using this twice a day for the first 5 days or so."

"It actually gives a nice glass-like finish to the skin, but when you use it every day, and let's say you have some post-acne marks, within a couple of weeks, I noticed that those marks have faded dramatically. And it does overall brighten your complexion. So, if you love a good vitamin C derivative, something that is really gentle, that doesn't oxidize, that you can use with a lot of other ingredients within your skin care routine, then this would be a great one to try."

"This Pro C serum just won an Allure award. [...] I really like this. I do feel like I can smell the furuic acid. Unlike the cleanser, this one is unscented, but it's not bad. And I really do feel like they have a formula that approaches hyperpigmentation in multiple different ways."

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.

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Tranexamic acid

Tranexamic acid has a growing body of clinical evidence for melasma and the stubborn patches of pigment that other ingredients struggle with.
