Along with this, the brownish guinea pig design has become utilized in several scientific studies by which pigmentation is induced by UV light or α-MSH. In the case of in vivo scientific studies, prevention of pigmentation induction by whitening agents is usually demonstrated using a Minolta chromameter or by histochemical scientific tests exhibiting a reduction in DOPA-constructive cells [239, 240]. One more animal test utilized for whitening scientific studies will be the zebrafish, that has also proved valuable in demonstrating the in vivo toxicity of whitening agents [241, 242].

Glycerol (103, Fig. fourteen) is one of the best humectants and has long been extensively Employed in topical moisturizing formulations. Together with its extremely hygroscopic Houses, glycerol enhances the moisturizing ability of the pores and skin by preventing the lamellar construction of SC from crystallization at pretty minimal humidity. This outcome of glycerol could be mainly because of the interaction in the glycerol molecules Together with the SC bilayer, which enhances the fluidity with the movie. The topical software of glycerol could also encourage the digestion of desmosomes by boosting the exercise of desquamatory enzymes, thus lowering SC’s dry and flaky visual appearance [205].
