Abstract

The invention relates to a whitening and freckle-removing composition and a preparation method and application thereof. The whitening and freckle-removing composition comprises, by weight, the following components: 0.1-1 part of phenethyl resorcinol, 1-5 parts of nicotinamide, 0.1-3 parts of a bearberry leaf extract, 0.1-3 parts of a mitracarpe scaber extract, 0.1-3 parts of vine tea extract, 0.1-3 parts of a ginger root extract, 0.1-1 part of polysorbate 80 and 0.5-5 parts of deionized water. According to the whitening and freckle-removing composition, the six components are matched accordingto the optimal proportion, the formula of the components is reasonable, the active ingredients complement each other to achieve synergistic interaction, the components inhibit the generation or transfer of melanin from all directions and multiple angles through different ways or mechanisms respectively, and the whitening and freckle-removing effect of the product is remarkable and long-acting. The composition is applied to cosmetics, so that the prepared product has high safety performance and remarkable long-acting whitening and freckle-removing effects.

Description

technical field [0001] The invention belongs to the technical field of skin care products, and in particular relates to a whitening and freckle-removing composition as well as its preparation method and application. Background technique [0002] The depth of skin color is regulated by many factors, mainly depending on the content and distribution of melanin. Melanin is an amino acid derivative, which is formed by a series of chemical reactions of tyrosine or 3,4-dihydroxyphenylalanine, and it often exists in the form of polymerization. Melanin is synthesized by melanocytes in the basal layer of the human epidermis. When ultraviolet rays irradiate the skin, the skin will be in a state of "self-protection", activate the activity of tyrosinase, and catalyze the synthesis of tyrosine or 3,4-dihydroxybenzene Alanine is oxidized to produce melanin, which protects our skin cells. Melanin moves through the layers of cell metabolism and reaches the epidermis of the skin to form fre...
