Abstract

The invention discloses an after-sun whitening composition. The after-sun whitening composition is prepared from the components such as a sedation and soothing agent, a moisturizing agent, a whiteningagent, and an antioxidant, wherein the sedation and soothing agent is prepared from one or more of allantoin, menthyl lactate, alcohol, witch hazel extract solution, and calendula officinalis flowerextract; and the whitening agent is prepared from one or more of lactic acid, niacinamide, glabridin, papaya extract and polyglutamic acid. The interaction of the components enables the composition ofthe invention to have good water supplementing and moisturizing efficacy, to sooth the after-sun skin, to alleviate the injury of the ultraviolet radiation on the skin, to inhibit the deposition of black pigments, to reduce the generation of speckles, and to achieve an after-sun whitening efficacy; and moreover, the composition can also be applied to cosmetics, so that the cosmetics can have significant after-sun whitening skincare efficacy.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to an after-sun whitening composition. Background technique [0002] Sun exposure will lead to skin aging and accelerate skin aging, generally manifested as pigmentation, dark yellow, accelerated formation of melanin and free radicals causing degeneration of skin elastic fibers. The formation process of melanin is as follows: tyrosine in human skin melanocytes is oxidized under the catalysis of tyrosinase to form dopa and dopaquinone, which are further oxidized after rearrangement to form dopachrome, 5,6-di Oxindole, indolequinone, and finally melanin. The main factors affecting the formation of melanin are: the number of melanocytes, the activity of tyrosinase, the content of oxygen free radicals and the content of tyrosine. Among them, tyrosine is an essential amino acid for the human body, and its content is controlled by the human body itself. Therefore, the ways of skin whitening ma...
