Description

technical field [0001] The invention relates to a moisturizing sunscreen and a preparation method thereof. Background technique [0002] Sunscreen is a skin care product that uses the principle of sunscreen to protect the skin from ultraviolet rays, thereby avoiding the production and accumulation of melanin. It is applied on the skin to prevent sunlight from contacting the skin. Inorganic sunscreen ingredients are usually inorganic substances such as zinc oxide and titanium oxide, which can reflect and scatter ultraviolet radiation; organic sunscreen ingredients are usually OMC and oxybenzoxazole, which can absorb ultraviolet radiation and convert radiant energy into heat energy. Many sunscreens protect the skin from both types of ultraviolet rays (UVA, UVB). UVA and UVB cause different damage to the skin. In addition to cosmetic problems, UV rays can cause many more problems, the most serious of which is skin cancer. From another point of view: it works through two ...
