Abstract

The invention discloses a skin sunscreen composition. The skin sunscreen composition comprises a natural anti-oxidant, a natural whitening agent, and a sunscreen agent; the natural anti-oxidant comprises one or more than one ingredients selected from radix scutellariae extract, tomato extract, and grape seed extract; the natural whitening agent comprises one or more than one ingredients selected from Kiwi fruit extract, watermelon extract, and towel gourd extract. The skin sunscreen composition is capable of inhibiting sunshine oxidation, reducing melanin accumulative, and reducing skin damage; when the skin sunscreen composition is applied in cosmetics, the cosmetics are provided with excellent sunscreen effects; most of the ingredients are natural ingredients, so that the skin sunscreencomposition is natural, and is high in efficiency.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a skin sunscreen composition. Background technique [0002] Sunscreen cosmetics refer to cosmetics that add sunscreen agents that can block or absorb ultraviolet rays to prevent skin from being tanned and sunburned. According to the principle of sun protection, sunscreen can be divided into physical sunscreen and chemical sunscreen. Appropriate sunscreen ingredients are added to sunscreen products to achieve the purpose of sunscreen. The tiny particles in physical sunscreens are generally composed of titanium dioxide, zinc oxide, etc. As for chemical sunscreens, sylates, cinnamates, and anthranilates are considered to be relatively safe and non-irritating sunscreen ingredients. Commonly used topical drugs include retinoic acid, kojic acid and other external preparations, which are prone to toxic and side effects.
