Question: is hyaluronic acid an aha?
Answer: The 'acid' in hyaluronic acid (HA) is a little deceiving. Exempt from any of the exfoliating/skin cell dissolving qualities that you'll find with AHAs and BHA, HA instead tackles hydration. A natural humectant, it's hailed as a superior ingredient for its ability to hold 1,000 times its weight in water.
