What the gurus are saying

This serum's 10% mandelic acid concentration earns praise for being a gentler exfoliant than glycolic acid, making it a solid pick if you're after chemical exfoliation without harshness. The formula also includes polyhydroxy acids to amplify the mandelic acid's effect and alantoin to calm skin afterwards. At ten dollars, the gurus found it hard to fault, though those with very sensitive skin may want to patch-test first and ease in slowly.

"It's $10 and has 10% mandelic acid in it. It also has some polyhydroxy acids in it that can boost the mandelic acid's effect. [Allantoin] can soothe the skin in this formulation as well. So really a great swap here."

"The Good Molecules Mandelic Acid Serum, this one is really nice. I've been testing it out now, the pH is good. Mandelic acid's a really great exfoliant, it's more gentle than glycolic acid. It's an exfoliant made from bitter almonds or maybe sweet almonds, I can't remember one of the two. So if you're into exfoliants, 10 bucks you can't beat that, you just really can't. So worth checking out."
