Good Molecules Hyaluronic Acid Serum

Updated Nov 8, 2026 · Top Hyaluronic acid serums

Best for A simple, fragrance-free hyaluronic serum when you do not need ceramides in the same bottle.

A light serum with two sizes of hyaluronic acid. Good Molecules lists it as fragrance-free, vegan, and pH 5.8, and says to put it on damp skin and then a moisturizer. That last instruction is the useful part. There is no dermatologist panel or lab hydration test for this bottle in the sources used here. It is the cheap, short formula if The Ordinary's texture pills on you. It will not outperform a richer serum on very dry skin.
