Aveeno's First Vitamin C Serum: What the '15% Pure Vitamin C' Comparison Really Means

Aveeno, the oat-focused skincare brand, now sells a Positively Radiant Vitamin C Serum, and its US site still tags it as a new product. NewBeauty included it in its July 2026 launch list and described it as the brand's first vitamin C serum. It is aimed at normal to dry, sensitive skin and comes as a 1 fl oz pump bottle without added fragrance.

The vitamin C here is not pure L-ascorbic acid. Aveeno's name for it is Vitamin Cg, and the ingredient list shows that this is ascorbyl glucoside, a stabilised derivative that the brand's professional site says converts gradually to vitamin C in skin. Aveeno does not give a percentage. Niacinamide is the second ingredient, while ascorbyl glucoside sits seventh, after glycerin, acetyl glucosamine, pentylene glycol and dimethicone. Ingredient lists generally run from most to least for anything above 1%, so this reads as a niacinamide-led formula with vitamin C alongside it.

The claim most likely to catch your eye is that the formula delivers greater antioxidant properties than 15% pure vitamin C. The footnote says this is based on an in vitro SOD test on the finished product. That is a measurement in a lab, not on a face, so it does not show that the serum brightens skin as well as a 15% L-ascorbic acid serum.

The other figures come from a consumer perception study over eight weeks: 93% agreed that the formula is not irritating, 87% agreed it leaves a natural glow, and 86% reported improvement in dull-looking skin. Aveeno's professional site gives the group size as 127 people. These are answers from users, and the pages describe no comparison group. The promise of glowing skin in one week is also the brand's own.

For readers in India, the practical point is availability. We did not find an Indian listing in our checks, and we do not convert foreign prices, so it appears on our site with the price as NA.
