The present invention relates to novel heterocyclic derivatives of 2-oxothiazolidine-4-carboxylic acid, to a process for synthesizing them and to compositions containing them. The invention also relates to the use of at least one heterocyclic derivative of 2-oxathiazolidine-4-carboxylic acid in a composition or for the manufacture of a composition, the said derivative or the said composition being intended to induce active photoprotection of the skin, advantageously to prepare the skin to receive sunlight and/or to protect the skin and other epidermal growths during or after exposure to UV. Another subject of the invention also relates to a cosmetic process for treating the skin by oral administration or topical administration to the skin of a cosmetic composition as defined above.
本发明涉及2-氧代噻唑烷-4-羧酸的新型杂环衍生物、其合成方法以及含有它们的组合物。本发明还涉及将至少一种2-氧代噻唑烷-4-羧酸的杂环衍生物用于组合物的制造或组合物中,所述衍生物或所述组合物旨在诱导皮肤的活性光保护,有利地准备皮肤接受阳光和/或在暴露于紫外线后保护皮肤和其他表皮生长物。本发明的另一个主题还涉及通过口服或局部给皮肤涂抹上述化妆品组合物的化妆过程,以治疗皮肤。
