What it is — N-Acetyl Cysteine (INCI: Acetyl Cysteine) is an amino-acid derivative and a precursor to glutathione, one of the body's own antioxidant molecules. In cosmetics it is used mainly as an antioxidant ingredient.

What it does — It is included to help defend the skin and scalp against everyday oxidative and environmental stress, and it appears in antioxidant-focused scalp formulas.

Typical use — It is found in scalp serums, tonics and some antioxidant skin treatments, usually as a supporting ingredient within a wider blend rather than a headline active.

Who it suits / good to know — Generally suitable for most skin and scalp types, and typically used at low levels. It is one supporting component of a routine rather than a standalone fix.

Safety — DHALIORA grades it low risk: an antioxidant with low irritation potential. This reflects the ingredient in general and is not medical advice; patch-test if your skin is easily irritated.

Why we grade it Low: Low risk - plant/vitamin antioxidant with low irritation potential.
