Hyaluronic acid
Good: Fine. Just not magic.evidence: moderatePEER-REVIEWED 2012
It's a water magnet: it binds and holds moisture, which is why it shows up in so many moisturizers. That's the whole trick, and it's a fine trick. But a plain fragrance-free moisturizer already covers hydration for you. If a serum costs extra just for hyaluronic acid, your wallet can relax: you're not missing anything your moisturizer doesn't do.
what the evidence says
Well documented as a humectant in peer-reviewed literature; no evidence teens need it as a standalone product.
