Cosmedica Pure Hyaluronic Acid Serum

Updated Nov 8, 2026 · Top Hyaluronic acid serums

Best for A simple hyaluronic serum with a short ingredient list, sealed with a cream.

Cosmedica sells a 2 oz hyaluronic serum and says the formula is short, vegan, and meant to be used morning and night. It does not print a percent the way The Ordinary prints 2 percent. The listing claims the acid holds a huge multiple of its weight in water. That is a property of hyaluronic acid in general, not a test of this bottle against Vichy or Hyalu B5. Put it on damp skin and cover it with a moisturizer. It is the extra serum if you want a plain bottle. It is not the one with a dermatologist quote in the Glamour test.
