First things first: what is it?

Hyaluronic acid is a water-binding molecule also found in the body. In skincare, its main job is hydration.

What does it do?

Hydration

Topical formulas containing hyaluronic acid have been studied for improved skin hydration.

Science or just a good story?

A review of topical hyaluronic acid reports hydration benefits across different formulas and procedures. We reviewed its abstract; these findings do not establish how every hyaluronic acid serum will perform.

Spot it on the label

  • Look for Hyaluronic Acid in the ingredient list.

So, is it a useful ingredient?

A hydration ingredient, not an exfoliating acid. Compare the whole formula, not the number of HA types advertised.
