Abstract

The invention relates to a sunburn protecting and repairing type cosmetic composition and a preparation method thereof. The cosmetic composition comprises the following raw materials and components inpercentage by weight: 1-5% of plant extractive, 1-5% of hydrogenated lecithin, 1-5% of an emulsifier, 1-5% of a co-emulsifier, 5-10% of a humectant, 0.1-1% of a thickening agent, 5-10% of an emollient, 0.5-10% of a functional additive, and 60-80% of water, wherein the plant extractive includes white perilla leaf extractive, pomegranate blossom extractive and terminalia ferdinandiana fruit extractive; the hydrogenated lecithin is hydrogenated soybean lecithin containing 60-80% of phosphatidylcholine. The cosmetic composition is capable of protecting skin from UV radiation and visible light andeven UV radiation mediated delayed sunlight induced irritation; skin can be effectively repaired at night, and the ageing of the skin is delayed.

Description

technical field [0001] The invention relates to cosmetics, in particular to a sunscreen repairing cosmetic composition and a preparation method thereof. Background technique [0002] The main way to prevent sun-induced skin damage is to prevent or reduce sun exposure. Of course, staying out of the sun at the right time can significantly reduce negative effects. Exposure to UV radiation is a major cause of physiological skin damage such as photoaging and erythema. [0003] However, skin damage doesn't just happen instantly in the sun. Sun-mediated skin stress can persist for hours after skin exposure to UV radiation and even continue at night. Sunlight induces oxygen and nitrogen free radicals, which activate the skin's own melanin. Melanin then transfers this excess energy to DNA, which ultimately leads to delayed skin damage, hence the name "dark CPDs." [0004] Thus, UV-induced skin damage can occur hours or even at night after radiation, and shockingly, half of all s...
