Abstract

The invention discloses a whitening and spot-fading composition. The composition is prepared from, by weight, 4-6 parts of a component A, 6-8 parts of a component B, 1-3 parts of enzyme powder, 0.2-0.4 part of troxerutin, 0.1-0.2 part of corrosion remover and 100-200 parts of water; the component A is prepared from, by weight, 0.3-0.5 part of chitosan, 0.1-0.3 part of polyglutamic acid, 0.1-0.3 part of allantoin and 3-5 parts of polyglutamic acid; the component B is prepared from, by weight, 4-5 parts of GTCC, 0.4-0.6 part of 4-hexylresorcinol and 1.5-1.9 parts of sep-40. By the cooperative effect of raw materials, the effects of excellent skin whitening, spot fading and skin brightening are achieved, the skin metabolism can be promoted, the skin is tender and fine-white, the high inhibiting effect is achieved on synthesis of melanin in melanoma, the color of spots caused by abnormal coloring matter can be rapidly faded, chromogenesis caused by sunshine can be better prevented, coloring matter caused by sunshine can be eliminated, and the damaged skin is repaired.

Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a composition for whitening and lightening spots and a preparation method thereof. Background technique [0002] When people's skin is irradiated by ultraviolet rays, melanin, which determines the color of human skin, is produced and released, thereby causing hyperpigmentation, such as melasma, freckles and spots, which have adverse effects on beauty. [0003] The synthesis process of melanin is as follows: tyrosinase in cells acts on tyrosine to form dopaquinone, thereby producing melanin. Therefore, in order to prevent darkening of the skin, researchers have devoted themselves to studying the inhibition of part of the synthesis process of melanin, thereby reducing the synthesis of melanin itself. Examples of such whitening agents developed are kojicacid, arbutin, licorice extract, vitamin A and vitamin C. [0004] Also, in addition to determining skin color, melani...
