OK, so what does glycolic acid actually do? Glycolic acid is an alpha hydroxy acid (AHA) and one of the most potent exfoliators available. A true powerhouse ingredient, it minimizes pores, treats hyperpigmentation, reduces the appearance of fine lines and wrinkles, and smooths skin. Glycolic acid is actually the smallest sized molecule of all the AHAs, meaning it’s easier for it to penetrate skin—that’s why it sometimes gives a tingly sensation. It works by speeding up cell turnover, helping dissolve the bonds that hold skin cells together, allowing any dead cells to be sloughed off more easily. It’s also known for supporting with collagen production too.

How you use glycolic acid is all down to your skin’s needs. If you’re looking to kick-start your routine with exfoliation, a glycolic acid face wash is a great way to add this ingredient into your ritual, or for a more concentrated boost try a glycolic acid serum to let it penetrate into skin for longer. Whatever your glow goals are, we have a lineup of glycolic acid products to help you crush them.
