Abstract

The present invention provides cosmetic compositions for topical application to the skin. The cosmetic composition comprises a vitamin B3 compound, a ricinoleate compound and a dermatologically acceptable carrier. The vitamin B3 compound and the ricinoleate compound favorably or even synergistically up-regulate proteasomal protease activity, as evidenced by the higher than calculated net luminescence values ​​observed in B16 melanoma cells.

Description

technical field [0001] The present disclosure relates to cosmetic compositions and methods for upregulating the activity of proteasome proteases. Background technique [0002] Beauty-conscious consumers are generally concerned with evenness of skin tone and / or the appearance of hyperpigmented spots, such as sun spots (age spots). As such, cosmetic compositions and methods for addressing these consumer concerns are areas of continuing high interest. In melanocytes, the ubiquitin-proteasome system is known to regulate skin pigmentation by degrading tyrosinase or microphthalmia-associated transcription factors. In addition, it is believed that upregulation of proteasome protease activity can lead to decreased melanin production within melanocytes. See eg Hakozaki et al., A regulator of ubiquitin-proteasome activity, 2-hexyldecanol, suppresses melanin synthesis and the appearance of facial hyperpigmented spots, British Journal of Dermatology 2013, 169 (Suppl. 2), pp. 39-44. S...
