What Betaine Salicylate does for your skin, who it suits, and what to watch for.

INCI: Betaine Salicylate

Promising, not proven

In short: Betaine Salicylate delivers exfoliation and anti acne, suits combination and oily skin best, and the evidence behind it is limited. One thing to know: clear it with your doctor if pregnant; introduce it gently.

The molecule

Tap to turn it in 3D

The two pieces are meant to be apart. Betaine Salicylate is a salt, and its parts are held to each other by opposite charges rather than by a bond.

The Glow take

Can help, with honest expectations.

When your goal is calming breakouts and congestion, Betaine Salicylate can genuinely help, though the evidence is still thin, so keep expectations gentle. Introduce it gently, and pair it with something soothing if your skin runs sensitive.
