DropBio® DHB is a gentle, long-lasting, and uniform self-tanning agent, derived from natural sources. Erythrulose reacts with free amino groups in the keratin of the epidermis through a Maillard reaction, producing a natural-looking tan comparable to the effect of sun exposure. Known for its slower, more uniform reaction compared to DHA, it minimizes the risk of streaks or an orange hue, providing a more even, natural tan.
