Definitions

  • the present invention relates to the use of
  • the epidermis contains in its lowest layer, the basal layer, in addition to the basal cells, individual pigment-forming cells, the melanocytes. UV light in these cells stimulates the production of melanin, which is transported to the keratinocytes (horny cells) where it becomes visible as a brown skin color. Melanin protects the cell nuclei from further irradiation and the resulting negative effects on the cell DNA.
  • the observed skin tone is determined by the ratio of these two types of melanin.
  • this pigmentation is primarily initiated by UVB radiation and is termed "indirect pigmentation.” Its development proceeds over several days, resulting in a few weeks of suntan is used, predominantly colorless melanin precursors are oxidized by UVA radiation to dark colored melanin. Since this oxidation is reversible, it leads to a short-lasting tanning of the skin.
  • An artificial tanning of the skin can be produced externally with the help of make-up and orally by taking carotenoids.
  • the artificial tanning of the skin which can be achieved by applying so-called self-tanner.
  • DHA 1,3-dihydroxyacetone
  • Self-tanning agents can be reacted with the proteins and amino acids of the horny layer of the skin in the sense of a Maillard reaction or via a Michael addition, whereby polymers which give the skin a brownish hue emerge via a not yet fully elucidated reaction pathway. This reaction is completed in about 24 hours. The tan thus obtained is not washable and is removed only with the normal Hautabschuppung.
