What does DHI do in skincare?
It helps develop a subtle tan-like colour by forming eumelanin on the skin’s surface.
Is DHI safe to use?
It requires careful formulation because it is a reactive pigment precursor, so it’s only used in specific, regulated self‑tanning products.
Who is DHI for?
It’s intended for people looking for a gradual self‑tan rather than a treatment effect.
