QUE SIGNIFIE HYDROXY ACID EN ANGLAIS
Alpha hydroxy acid
Les α-hydroxy-acides ou les acides alpha-hydroxy sont une classe de composés chimiques qui consistent en un acide carboxylique substitué par un groupe hydroxyle sur le carbone adjacent. Ils peuvent être naturels ou synthétiques. Les AHA sont bien connues pour leur utilisation dans l'industrie cosmétique. On les trouve souvent dans des produits qui prétendent réduire les rides ou les signes du vieillissement, et améliorer l'apparence générale de la peau. Ils sont également utilisés comme peaux chimiques disponibles dans les bureaux d'un dermatologue, des spas de beauté et de santé et des kits d'habitation, qui contiennent habituellement une concentration inférieure d'environ 4%. Bien que leur efficacité soit documentée, de nombreux produits cosmétiques sont apparus sur le marché avec des allégations de performance infondées. Beaucoup d'acides α-hydroxy bien connus sont des blocs de construction utiles dans la synthèse organique: le plus commun et le plus simple sont l'acide glycolique, l'acide lactique, l'acide citrique, l'acide mandélique.
