What DHA actually does

DHA (dihydroxyacetone) is a simple sugar that reacts with the outermost dead cells of your skin to produce a brownish colour. The reaction happens within the stratum corneum — the surface layer that naturally sheds over one to two weeks. It is a colour reaction, not a stain, not a dye, not a treatment. The depth of colour is determined by DHA concentration, the number of layers applied, your skin's own texture, and how recently you exfoliated. Format is just the delivery vehicle.

Format guide

• Mousse — fast-drying, opaque, for experienced hands. Default for confident application.
• Lotion — slower dry time, more forgiving, best for first-timers and large areas.
• Drops — maximum control, build depth over consecutive nights, face-safe.
• Tanning water — lowest DHA, most subtle, multiple rounds for visible colour.
• Foam spray — for hard-to-reach areas, always use with mitt to blend.
