Abstract

The invention discloses a mild freckle removing composition and a preparation method thereof. The invention discloses a composition, and the composition is prepared from, by weight, 5-40 parts of phenethyl resorcinol, 5-55 parts of butyl resorcinol and 0.5-5 parts of oat alkaloid. The butyl resorcinol can inhibit activity of tyrosine and tyrosinase and prevent the tyrosine and the tyrosinase fromgenerating a signal of producing melanin, thereby having the effect of inhibiting melanin generation, the phenethyl resorcinol having performance of reducing oxygen radicals and optimizing oxidation resistance is added, and the oat alkaloid is a substance extracted from oat bran, is the alkaloid containing phenolic hydroxyl, and has multiple biological activity of inflammation resistance, oxidation resistance, itch relieving, skin relieving and the like, the compound of the three substances has a synergistic effect of whitening, removing freckle and resisting inflammation, the composition cansignificantly improve skin and skin elasticity, the effect is obviously better than that of adding one or two substances, and the composition is safe and non-irritant.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a mild freckle-removing composition and a preparation method thereof. Background technique [0002] Skin dullness and blemishes are the result of uneven distribution and accumulation of melanocytes in the surface layer of the skin. Melanin is synthesized by melanocytes present in the basal layer of the epidermis. The precursor tyrosine in the melanosomes generates melanin under the action of tyrosinase. The abnormal increase of this melanin in the epidermis causes patients to develop chloasma. Melanin is the most important pigment in the skin, it determines our skin color. At the same time, melanin is also the natural defense system of human skin, which can resist the damage of ultraviolet rays to the skin. However, when melanin is produced too much or unevenly distributed, it will lead to pigmentation and dark spots, which will affect the appearance. With the advancement of...
