Description

technical field [0001] The invention relates to a sunscreen, in particular to an oil-in-water sunscreen and a preparation method thereof. Background technique [0002] Sunlight is the most direct external factor that causes skin aging and darkening. Unprotected skin will cause premature wrinkles, spots, and rough skin due to sunlight. According to different wavelengths, ultraviolet rays are divided into three types of ultraviolet rays: UVA (ultraviolet rays) A, wavelength 320-400 nanometers, long wave), UVB (wavelength 280-320 nanometers, medium wave), UVC (wavelength 100-280 nanometers, short wave). The penetration of UVA ultraviolet rays to clothing and human skin is much stronger than that of UVB ultraviolet rays. It can reach deep in the dermis and act on the melanin in the epidermis, thereby causing skin melanin pigmentation and darkening the skin. Therefore, UVA ultraviolet rays are also known as As a "tanning stage", although UVA ultraviolet rays do not cause acute s...
