Use of carotenoids in cosmetic compositions e.g. for stimulating keratinocyte proliferation, inhibiting keratinocyte differentiation, promoting epidermal renewal or regeneration or promoting wound healing

摘要

Carotenoids are used in cosmetic compositions for stimulating keratinocyte proliferation, inhibiting keratinocyte differentiation, promoting epidermal renewal or regeneration, increasing epidermal thickness, promoting wound healing and combating the effects of menopause on the epidermis, on keratinocyte proliferation and on epidermal thickness. An Independent claim is also included for a method for cosmetic treatment of the epidermis to stimulate keratinocyte proliferation, epidermal renewal and/or epidermal regeneration and/or increase epidermal thickness, in which a cosmetic composition comprising at least one carotenoid is applied to the skin, hair and/or mucosa or is ingested.
