When you apply Oveallgo Intensive Tanning Luxe Gel to your body, DHA works by reacting with dead skin cells on the surface of your body. Essentially, your dead skin cells are darkened to mimic a sun-kissed glow. Keep in mind, this darkening of the skin is just that, momentary. This active agent reacts chemically with the amino acids in the stratum corneum. As a result of this non-UV Maillard reaction, melanoidin pigments gradually form and provide the appearance of a tan.
