Nothing. None of the experts who reviewed it raised a problem.

What the gurus are saying

The 9% lactic acid concentration paired with glucanolactone (a gentler exfoliant) makes this serum well suited to sensitive skin, where it helps refine texture and brighten dull patches without harsh irritation. Gurus praise its lightweight, thin consistency for easy absorption, and note it works particularly well on textured areas like bumps on the back of the arms and the face.

"Exfoliating with lactic acid is also a big helpful one. Shani Darden has just come up with her Lactic Acid Exfoliating Serum. It is a very lightweight serum and it's really not very irritating. Glycolic tends to be more irritating than lactic acid. If you are somebody who has darker skin tone scared of getting irritated by an exfoliating acid, lactic acid is going to be your gem and it also helps with pigmentation."

"Shani Darden also makes an amazing lactic acid serum too which is so nice for brightening. This is a beautiful, very thin consistency so it really absorbs into the skin nicely. It's so good I love that as well."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Alpha hydroxy acids

Alpha hydroxy acids loosen the bonds holding dead cells at the surface. The evidence supports smoother texture and more even tone over time, and they can leave skin more sensitive to sun.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Vitamin E

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
