Sodium heparin

The sodium form of heparin, a sugar-based molecule the body makes naturally, used in skincare in small amounts as a conditioning ingredient.

What it does: Used in toners, pads, cleansers and gel creams marketed for post-blemish marks, usually beside onion extract, and in a calming barrier cream.
How often: Morning and evening in the pads, cleanser, toner and creams; use sunscreen with the retinal cream during the day.
