FunctionSkin conditioning

What it is — Menadione (INCI: Menadione), also known as Vitamin K3, is a synthetic vitamin K compound used for its purported skin-conditioning character.

What it does — It is included as a conditioning ingredient; formulators typically use it at low levels within a wider blend.

Typical use — Appears occasionally in targeted skin-conditioning formulas rather than as a mainstream everyday active.

Who it suits / good to know — More of a niche ingredient; some brands avoid it altogether. If your skin is reactive, approach unfamiliar conditioning agents cautiously.

Safety — DHALIORA grades it high risk in its EWG-style review: some formulations avoid it due to historical sensitization concerns reported at higher concentrations. This is general information, not medical advice. Patch-test before wider use and discontinue if irritation occurs.

Why we grade it High: High risk — some formulations avoid it due to historical sensitization concerns at higher concentrations.
