"Patients love the Allies of Skin Vitamin C 35% with glutathione advanced firm and brighten serum. This one retails for $148. It's a combination of vitamin C and glutathione which makes it work really well but it might be a little bit strong if you are sensitive because it does have ascorbic acid in it and it could be very very active."

New Vitamin C! Tetrahexyldecyl Ascorbate & 3-O Ethyl Ascorbic Acid | Dr. Shereene Idriss

"But there are several things that bother me about this. [...] Number one, it's marketed as a 35% vitamin C when it's not. It's actually a complex. [...] They actually have 10% of tetrahexyldecyl ascorbate and 25% of ethylated L-ascorbic acid. [...] I have to question whether 10% is really necessary when we know that at 2% your skin is getting the benefits. This one retails for around 115 dollars, and because THD is very expensive I wonder about that concentration."

"I really think this is hybrid at its best. Using that pure form, but stabilized vitamin C alongside derivatives together to be a match made in heaven. I love it. It doesn't come with the cheapest price point, though, [...] but if you see this almost like an entire skincare routine in a bottle, that's where I think you can really make some streamlining and cost savings using this versus four other serums that you might be reaching for."

"The Allies of Skin Vitamin C 35 Collagen Building is really wonderful. They use Tetra hexyl Decyl Ascorbate as well as ethyl ascorbic acid. It's very expensive though, and it does tend to be a little bit greasy. For collagen building, ascorbic acid has been proven to build collagen in your skin. The derivatives I'm not so sold that those are totally gonna do the trick."

"This is the 35% Vitamin C Perfecting Serum [...] and what's amazing about this is that it's an oil-soluble form of vitamin C. [...] This can actually absorb into the skin because our skin is [...] made up of oil and most vitamin C is water soluble, meaning it has a hard time getting in. [...] Using an oil soluble vitamin C it can actually penetrate into the skin and get into the nucleus of the cell where it needs to work on things like hyperpigmentation fine lines and wrinkles."

Top Pick: vitamin c serum for dry skin

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.
