Biological sunscreen milk

Abstract

The invention discloses biological sunscreen milk, which is prepared from the following ingredients including tetrahydropyrimidine carboxylic acid, edelweiss extracts, tea powder extracts, dunaliella salina extracts and kaempferia galangal root extracts. The biological sunscreen milk uses biological agents and exact monomer ingredients from natural plant resources; the injury on the skin caused by ultraviolet rays, visible light, tobacco, environment pollution and extreme conditions can be timely blocked and restored; the light transmission rate is reduced; the exogenous aging is retarded.

Description

technical field [0001] The invention relates to the technical field of anti-sunning isolation milk, in particular to a biological sunscreen. Background technique [0002] Traditional ultraviolet absorption (chemical sunscreen) relies on absorbing ultraviolet rays, photon migration, converting ultraviolet rays into heat energy, releasing heat, heat energy will lead to increased secretion of sweat glands, especially in water-in-oil systems, heat is more difficult to release, in extreme environments not only It will not protect the skin or even irritate and burn the skin; most of the ultraviolet absorbers will penetrate the skin and cause skin allergic reactions, irritant contact dermatitis and photosensitivity reactions, damage the skin cell structure, and may also disrupt hormones. [0003] Pure physical sunscreens have poor sunscreen effect, narrow sunscreen wavelength range, poor smear feeling, dry and astringent skin, serious white floating powder phenomenon, powder is eas...

[0002] Traditional ultraviolet absorption (chemical sunscreen) relies on absorbing ultraviolet rays, photon migration, converting ultraviolet rays into heat energy, releasing heat, heat energy will lead to increased secretion of sweat glands, especially in water-in-oil systems, heat is more difficult to release, in extreme environments not only It will not protect the skin or even irritate and burn the skin; most of the ultraviolet absorbers will penetrate the skin and cause skin allergic reactions, irritant contact dermatitis and photosensitivity reactions, damage the skin cell structure, and may also disrupt hormones

[0003] Pure physical sunscreens have poor sunscreen effect, narrow sunscreen wavelength range, poor smear feeling, dry and astringent skin, serious white floating powder phenomenon, powder is easy to cause accumulation to block pores, and photocatalytic effect is serious, which will not only degrade the ingredients in the formula, but also It will produce a large number of free radicals attached to the skin surface and cause skin aging, causing skin protein decomposition, which is harmful to the skin and human body

At the same time, when combined with chemical UV absorbers, it will accelerate the instability and degradation of UV absorbers, lose the effect of photoprotection, and bring potential risks
