CeraVe Skin Renewing Vitamin C Serum (10% Pure) vs The Inkey List Polyglutamic Acid Serum
Both serums contain Hyaluronic Acid, but only CeraVe Skin Renewing Vitamin C Serum (10% Pure) adds a targeted active: Vitamin C. That's the main thing to weigh.
A 10% pure L-ascorbic acid serum on the CeraVe ceramide base with hyaluronic acid. An affordable, barrier-friendly vitamin C; pure ascorbic means it's potent but less stable than derivative forms, so store it cool and dark.
A hydration serum using polyglutamic acid, which holds even more water than hyaluronic acid, layered with HA. A lightweight, plumping hydrator that works well over or under HA; an affordable way to trial the ingredient.
