Problems solved by technology

The commonly used ultraviolet shielding agents are titanium dioxide and zinc oxide. Although they are non-irritating to the skin, the comfort and naturalness of use need to be improved; most of the ultraviolet absorbers are synthetic organic compounds, such as UVA absorbers (such as anthranilic acid esters and dibenzoylmethanes, etc.), UVB absorbers (such as cinnamate, salicylate) and broad-spectrum absorbers (such as benzophenones, bis-ethylhexyloxyphenol methoxyphenyl Triazines, etc.), these substances have certain safety hazards for sensitive skin; biological sunscreens mainly play a sunscreen role through anti-free radicals, anti-oxidation, and absorption of ultraviolet rays, and most of them are extracted from natural animal and plant raw materials. substances, such as aloe vera, grape seed extract, emblical, etc., with high safety

Abstract

The invention discloses a dendrobium officinale fermentation extracting solution, a skin care product and a preparation method of the skin care product. The dendrobium officinale fermentation extracting solution has high scavenging power on three free radicals including .OH, DPPH and ABTS, has high inhibiting power on tyrosinase and has good broad-spectrum ultraviolet absorptivity. The skin care product takes the dendrobium officinale fermentation extracting solution as a main active ingredient, a small amount of sunscreen ingredients and ingredients beneficial to skin are added, the protective ability, the repairing ability and the water-oil balance ability of the skin on ultraviolet rays are enhanced from the perspectives of free radical oxidation resistance, ultraviolet absorption, ultraviolet shielding, tyrosinase resistance and the like, the potential irritation of sunscreen and whitening cream is effectively reduced, and the problems of skin sunscreen, moisturizing, whitening, repairing and the like are solved. The skin care product is high in sunscreen index, the naturalness of the skin smeared with the skin care product is greatly superior to that of other existing sunscreen products with the same sunscreen index, and meanwhile the product has the characteristics of being good in smearing comfort, beautiful and natural in skin color after being smeared and good in stability.

Description

technical field [0001] The invention relates to the field of daily cosmetics, in particular to a dendrobium officinale fermented extract, a skin care product and a preparation method thereof. Background technique [0002] The daily skin care is mainly sunscreen, moisturizing, and anti-oxidation. The corresponding skin care products are commonly used sunscreen, moisturizing cream, whitening cream, etc. [0003] The key to the development of daily sunscreen skin care products is the selection of sunscreen agents. Commonly used sunscreen agents are divided into ultraviolet shielding agents, ultraviolet absorbers, and biological sunscreen agents. The commonly used ultraviolet shielding agents are titanium dioxide and zinc oxide. Although they are non-irritating to the skin, the comfort and naturalness of use need to be improved; most of the ultraviolet absorbers are synthetic organic compounds, such as UVA absorbers (such as anthranilic acid esters and dibenzoylmethanes, etc.),...
