Application

A sun-tanned appearance is a symbol of a healthy, dynamic, and active life. Yet, the damaging effects of sunlight and other sources of ultraviolet radiation on the skin are well documented. These effects are cumulative and potentially serious, and include sunburn, skin cancer, and premature aging of the skin.

LGB® DHA has been used in cosmetic self tanning products for many years, but it does have many disadvantages which have been troubling the people. Therefore, there is an eager desire to find a more safe and effective self-tanning agent to supersede LGB® DHA.

LGB® ERL has been developed to reduce or even eliminate the disadvantages of LGB® DHA, namely an irregular and streaky tan as well as an intense drying effect. It presents a new solution for the increasing demand of self-tanning. It is a natural keto-sugar occurring in Red Raspberries, and may be produced by fermentation of the bacterium Gluconobacter followed by multiple purification steps.

LGB® 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 LGB® ERL after 4 to 6 days. The tanned appearance typically lasts from 2 to 10 days depending on application type, and skin condition.

The coloring reaction of LGB® ERL with skin is slow and gentle, which makes it possible to produce a natural, long-lasting, even tan without stripes (LGB® DHA may create an orange tone & stripes). As an up-and-coming self-tanning agent, LGB® ERL only sunless tanning products have become increasingly popular.
