Description

Skin care compositions

Technical Field

The invention relates to the field of skin care products, and particularly relates to a skin care composition and application thereof.

Background

People working near a computer for a long time have very fast skin aging speed, and the static electricity of the computer is easy to lead the skin to adsorb dust, block pores for a long time, form acne and blackheads and even cause other more serious skin problems; meanwhile, the facial skin loses a large amount of water by computer radiation, and dead skin is generated. If the dirt and dead skin are not cleaned in time, cells are accumulated on the surface of the skin to block pores, so that the pores are large and the skin is rough. Therefore, there is a need to find a skin care product with high cleansing.

The 'blue light' is commonly called 'high-energy short-wave blue light', and is light with a wavelength of 400-480 nm and relatively high energy. Blue light pollution refers to exposure to artificial blue light of "hyperlinked lifestyle", which is mainly from computers, projectors, movie screens, LED displays, mobile phones, laser pens, fluorescent lamps, outdoor light boxes, LED lights and bathroom heaters. Blue light not only affects the secretion of melatonin, but also has a significant inhibitory effect on melatonin, which is a hormone assisting sleep. People not only disturb the normal biological clock of the human body when contacting blue light for a long time or before sleeping, but also cause a series of health problems such as insomnia and the like caused by the reduction of melatonin in the human body. In daily life, people are exposed to blue light more and more frequently, so that skin is excessively exposed to the blue light, and the self-barrier repair capacity of the skin is reduced, and aging is accelerated. Therefore, there is a need to find a skin care product that is resistant to blue light.

Masks remain a robust growth as a class of skin care products most commonly used by female consumers on a daily basis throughout the world. The data show that the annual average composite growth rate of the global mask market scale in 2013-2017 reaches 12.6%, and the global mask market scale in 2017 is $ 63 hundred million. Along with the development of the consumption habits of facial masks of Chinese consumers, China develops the largest market of the facial masks in the world, the consumption of the facial masks is huge in the market of Chinese skin care products, one of the facial masks is convenient to use, the facial masks can be applied while working, the other facial masks are safe and reliable, the facial masks are disposable, the third facial masks have better effects, air is temporarily isolated, and absorption of facial mask liquid is promoted.

The mask base cloth on the market at present mainly comprises non-woven fabrics and silk masks, and the non-woven fabrics have the advantages of large thickness and more essence bearing capacity; the non-woven fabric has the defects that the non-woven fabric has insufficient affinity with skin, is not beneficial to the absorption of facial mask liquid by the skin, and has higher sensitization rate compared with other membrane cloths. For the silk mask, a consumer often misunderstands that the silk mask plays a role, the nature of the silk mask and the nature of non-woven fabrics are almost the same, the silk mask and the non-woven fabrics are pure carriers, the materials do not play a role on skin, the silk mask plays a role in reality, the silk mask is popular with the non-woven fabrics, the most important improvement is light and thin, the consumer does not need to apply thick non-woven fabrics, and the silk mask is lighter and thinner, so that the skin affinity is remarkably improved, and the skin can absorb the facial mask liquid better. However, silk has a big problem because it is light and thin and can support less facial mask solution than non-woven fabrics.

CN109023714A discloses a high-moisture blue-light-resistant radiation-proof mask base cloth and a manufacturing method and application thereof, wherein the method comprises the following steps: (1) preparing fibers: mixing lutein and catechin according to a mass ratio of 1: 1-5: 1, and mixing the lutein and the catechin according to a mass ratio of 1: 10, adding the mixture into prepared cellulose spinning solution, mixing and modifying, and performing wet spinning after blending to obtain functional fibers; (2) preparing membrane cloth: adding 20-50% of the functional fiber and 50-80% of the alginate fiber for blending, opening, mixing, carding to form a web, and carrying out spunlace reinforcement to prepare a non-woven fabric with the density of 20-50 g/m 2; the blue-light-resistant radiation-proof mask base cloth is prepared by drying, winding and forming and then punching and cutting, so that the problem that a blue-light-resistant radiation-proof mask specially aiming at blue light radiation is lacked in the prior art is solved; however, the patent realizes blue light resistance through a membrane cloth based on a water-insoluble spinning technology, which is not beneficial to the absorption of lutein.

Therefore, in the field of skin care products, there is a strong need for blue light resistant, high cleaning skin care compositions.
