[0006] CN 105796475 A discloses moisturizing and anti-aging cosmetics containing kohlrabi extracts and a preparation method thereof. The cosmetics include the following components: 5-15 parts of kohlrabi extracts, 0.6-3.2 parts of vitamins, and 1-5 parts of antioxidants , 3-12 parts of anti-wrinkle active agent, 1-3 parts of sunscreen agent, 0.5-2 parts of anti-sensitivity agent, 2.5-6 parts of whitening agent, 2-12 parts of moisturizing agent, 0.03-0.2 parts of potassium hydroxide, ingot maple seed 0.5-2 parts of oil, 0.3-1.2 parts of chelating agent, 0.1-0.3 parts of thickener, 1.5-5.8 parts of emulsifier, 0.2-1 part of preservative, 40-80 parts of deionized water, which can improve skin elasticity and delay skin aging. Effects such as aging, but weak photoprotective effect
[0007] Therefore, sunscreen products that only target UVA and UVB can no longer fully protect the skin, and it is necessary to study a full-band photoprotection product to resist the damage of UVA, UVB, HEV and infrared light to the skin

Abstract
The invention provides a light protection composition and its preparation method and application. The composition comprises: ultraviolet absorber, carnosine, sunflower flower extract, golden chamomile extract and tocopheryl acetate. In the photoprotective composition of the present invention, carnosine, sunflower flower extract, golden chamomile extract and tocopheryl acetate are synergistically synergistic and used in conjunction with ultraviolet absorbers to achieve the effect of resisting full-band light radiation, which not only enhances the Resistant to UVA and UVB, but also resistant to blue light and infrared light.
Description
technical field [0001] The invention belongs to the technical field of cosmetics, and relates to a photoprotective composition and a preparation method and application thereof. Background technique [0002] In recent years, the destruction of the ozone layer has led to excessive sunlight exposure worldwide and a significant increase in skin diseases. Skin sun protection has attracted widespread attention. The wavelength range of the ultraviolet spectrum in sunlight is 200-400nm, which can be divided into 3 bands, namely short-wave ultraviolet (UVC) with a wavelength of 200-290nm, medium-wave ultraviolet (UVB) with a wavelength of 290-320nm and 320-400nm long-wave ultraviolet (UVA). Among them, UVA has a strong penetrating power, can directly reach the dermis of the skin, destroy elastic fibers and collagen fibers, tan the skin and produce wrinkles; UVB has an erythema effect on the human body, and long-term or excessive exposure will cause the skin to tan , and cause redne...
