The Ordinary Glycolic Acid 7% Toning Solution

Glycolic Acid (7%): This is an alpha hydroxy acid (AHA) derived from sugar cane. It works by exfoliating the skin, removing dead skin cells, and promoting cell turnover. A higher concentration (like the 7%) makes it more effective at resurfacing the skin and improving its texture, but it can also be more irritating, especially for sensitive skin.
