Disodium Laureth Sulfosuccinate: what it is in skincare

A gentle co-surfactant that helps boost foam while softening the feel of stronger cleansers.

What it does

Function: surfactant (mild anionic). Surfactants lift away oil, sunscreen and grime. K-beauty favours mild amino-acid and amphoteric surfactants that clean without stripping.
