Description

technical field [0001] The invention relates to a sunscreen and whitening skin care composition and a preparation method thereof, belonging to the technical field of skin care cosmetics. Background technique [0002] The skin is a traffic light for health. Appropriate absorption of sunlight can help the body produce vitamin D3 and prevent liver diseases. However, if exposed to the hot sun for a long time, the skin will become painful and dark, and even allergic dermatitis will occur, and skin cancer will be caused when the sun is severe. The sun is a huge source of radiation, which radiates a large amount of energy into space every moment. The ultraviolet rays in it can penetrate the surface of the skin, destroy skin cells and make the dermis of the skin gradually harden, dry the skin, lose its elasticity, and accelerate aging and wrinkles. Even on cloudy days, 70% of UV rays are still projected onto the ground. In recent years, due to the continuous expansion of the ozone...
