A natural keto sugar ((S)-1,3,4 trihydroxy-2-butanone) sunless tanning agent. originated from glucose; Achieves a tan that looks more natural and authentic. Often combined with Sunsafe DHA.provides darker, more evenly distributed tan. Sunsafe-ERL reacts with free primary or second amino groups of keratin in the upper layers of the epidermis. This conversion of reducing sugar with amino acids, peptides or proteins, similar to the “Maillard reaction”, also known as non-enzymatic browning, leads to the formation of brownish polymers, the so-called melanoids. The resulting brown polymers are bound to proteins of the stratum corneum mainly via lysine side-chains. The brown color is comparable to the appearance of natural sun tan. Tanning effect appears in 2-3 days, the maximal tanning intensity is reached with Sunsafe-ERL after 4 to 6 days. The tanned appearance typically lasts from 2 to 10 days depending on application type, and skin condition.
