Glycolic Acid is arguably the most famous alpha hydroxy acid (AHA) with tons of research backing its benefits.
It is found naturally in sugar cane but the form used in skincare is usually synthetic for purity and stability.
Glycolic acid removes the top layer of dead skin cells to allow newer and fresher ones to emerge.
AHAs work by breaking down the structural âglueâ that holds old skin cells in place. When that buildup is gone, your skin can renew itself more efficiently.
Research also shows glycolic acid stimulates collagen production, helping to firm and thicken the skin over time. This is one of its biggest advantages over other AHAs.
Overall, glycolic acid helps with:
Fun fact: Glycolic acid boosts skin hydration by helping it produce molecules that increase hyaluronic acid naturally.

It is normal to feel a slight stinging sensation when using glycolic acid. This usually fades as your skin adjusts.
Because glycolic acid has the smallest molecular size in the AHA family, it can penetrate deeper, which enhances its effectiveness but also makes it more likely to irritate sensitive skin.

Recent studies suggest glycolic acid might even help protect against UV damage. But donât skip sunscreen! Freshly exfoliated skin is more sensitive to the sun.
Glycolic acid is a skincare superstar. It smooths, brightens, hydrates, and firms the skin. Unless youâre highly sensitive, itâs well worth adding to your routine.
