Photoprotection repair composition and preparation method and application thereof and skin care product

Abstract

The invention discloses a photoprotection repair composition and a preparation method and application thereof and a skin care product, the photoprotection repair composition comprises photoprotectionextract and kidney vetch extract, wherein the photoprotection extract comprises at least two of brine shrimp extract, spirulina maxima extract and chlorella vulgaris extract. According to the composition, by adopting the synergistic effect of the kidney vetch extract and at least two of the three photoprotection extract, the protection range of the composition can cover wavelength regions of ultraviolet light, blue light and red light, and a large number of active DPPH free radicals produced by photoinduction can be removed, so that the the resistance to external harmful light rays is improvedby improving the resistance and repairing capacity of the skin; meanwhile, the composition can carry out mitochondrial DNA repair, and can protect the skin from the ultraviolet light, the blue lightand the infrared light comprehensively. In addition, the composition is safe, free of side effects, simple in preparation method, wide in applicability and suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a photoprotection and restoration composition, a preparation method and application thereof, and a skin care product. Background technique [0002] Light pollution is a new source of environmental pollution after waste gas, waste water, waste residue and noise pollution.

Problems solved by technology

[0003] The skin is the first line of defense of the human body. The ultraviolet rays in the sun are mainly divided into three parts: UVA, UVB, and UVC. Most of the UVC is radiated and scattered by the ozone layer and the atmosphere. UVA can directly penetrate into the deeper dermis of the skin and damage elastic fibers. And collagen fibers, long-term accumulation will cause skin damage, especially aging and relaxation of skin, deepening of wrinkles, loss of elasticity, melanin precipitation, etc., UVB level energy is high, long-term or excessive exposure will cause skin erythema, inflammation, aging , so excessive ultraviolet rays will cause problems such as photoaging and photodamage of the skin. If not prevented in time, it will damage cell DNA, activate proto-oncogenes, and cause skin tumors; and blue light is due to the popularity of electronic products, which increases people's exposure to blue light. risk of injury

As the band with the shortest wavelength and the highest energy in the visible spectrum, blue light has a stronger penetrating ability than ultraviolet light, so it is easier to penetrate into the dermis of the skin, and a large amount of active oxygen will be generated under the radiation of blue light. Degrade collagen, increase the synthesis of matrix metalloproteinase MMP, accelerate the aging process of the skin, cause oxidative damage, cause skin aging, and cause serious damage to the skin

In addition, infrared radiation accounts for 40% of solar radiation. People have recognized its harm long ago, but there are relatively few studies on the harm of infrared radiation to the skin.
