What Makes a Hyaluronic Acid Serum Effective
Effective hyaluronic acid serums use low molecular weight hyaluronic acid and multiple molecular weights to penetrate different skin layers. Formulations with 1% to 2% hyaluronic acid, combined with humectants like glycerin and panthenol, show measurable increases in skin hydration in consumer testing and dermatological studies. Brands such as The Ordinary, CeraVe, and La Roche-Posay publish ingredient lists and molecular weight specifications on their official sites La Roche-Posay.
Serums with patented delivery systems, such as encapsulated hyaluronic acid or hyaluronic acid combined with ceramides, aim to reduce transepidermal water loss. The International Journal of Cosmetic Science and other peer reviewed publications report that multi weight hyaluronic acid blends improve skin elasticity and hydration more than single weight formulas Forbes.
