Glycolic Acid is arguably the most famous AHA with research to back up its benefits. Its main role is to peel the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and look more even.

Glycolic Acid has shown to boost collage production, a protein that helps skin stay firm. Overall, Glycolic Acid helps with improving uneven tone, rough patches of skin, fine lines, wrinkles, and sun damage. It also increases skin hydration by playing a role in creating molecules that create hyaluronic acid naturally.

When applying Glycolic Acid, it is normal to feel slight stinging. The pH value and concentration of glycolic acid play a role in the effectiveness of the product.

Recent studies have shown Glycolic Acid may protect the skin against UV damage. However, you should always wear SPF, especially when using exfoliants.
