Description

Repair cream containing ergothioneine and preparation method thereof

Technical Field

The invention relates to the technical field of cosmetics, in particular to a repair cream containing ergothioneine and a preparation method thereof.

Background Art

Nowadays, with the promotion effect of various short videos and soft articles, the skin care process of "cleansing-water-lotion-essence-eye cream-face cream-sunscreen" has long been deeply rooted in people's minds. This has also caused consumers to fall into a misunderstanding about skin care, always thinking that the more skin care products I apply on my face, the better the skin care effect will be. Especially as I age, my skin condition becomes worse and worse. In order to improve my skin, consumers spare no effort to apply all kinds of skin care products on their faces, but this approach often yields little results, especially after the skin age is 40+, even if a thick layer of skin care products is applied on the face, the skin still feels "dry".

As we all know, with the increase of age, the absorption capacity of the skin is bound to become worse and worse. This is an irreversible natural aging process of the skin. With the increase of age, it is bound to be more and more difficult to improve the absorption capacity of the skin. No matter how many skin care products are applied on the face, if they cannot be truly absorbed by the skin, it will not make our skin better and better. On the contrary, this will not only make skin care a cumbersome thing, but also increase the burden on the skin to a certain extent. Especially for consumers with skin age of 40+, they should pursue easily absorbed skin care products instead of applying more skin care products on their faces. At present, most of the skin care products on the market for skin age of 40+ focus on anti-aging. Not only are the effects single, but even if many effective anti-aging ingredients are added to such products, the actual anti-aging effect is often unsatisfactory. You know, even if the skin care ingredients are the same, due to the poor absorption capacity of skin age of 40+, its skin care effect is always not as good as that of young skin age. Therefore, it is very necessary to develop a multi-functional and easily absorbed skin care product for skin age of 40+ to maximize the absorption capacity of skin care ingredients for elderly skin age and achieve better skin care effects.

Summary of the invention

In order to solve the problem of poor absorption capacity of 40+ skin age, the present application provides a repair cream containing ergothioneine and a preparation method thereof. The present application is a combination formed by a unique formula, especially by synergistic action of soybean polypeptide, kaempferia root extract, ergothioneine, palmitoyl pentapeptide-4, and biosaccharide gum-1 through different mechanisms of action on the skin, to achieve the effect of enhancing the absorption capacity of the skin, even if the skin of 40+ skin age is after using the repair cream containing ergothioneine prepared by the present application, it can still have a good absorption effect, and realizes the skin care effect of moisturizing, whitening, and anti-aging multi-effect integration, which perfectly embodies the "streamlined skin care" concept of skin care in fine rather than in large quantities.

Table 1:

Table 2:

Table 3:

The above test results show that Examples 1-10 have better absorption effect, moisturizing effect, whitening effect, nourishing effect and anti-aging effect than Comparative Examples 1-5.

It can be seen from the comparison of Example 3 and Comparative Examples 1-5 that the absorption capacity of Example 3 is better than that of Comparative Examples 1-5, and the absorption effect, moisturizing effect, whitening effect, nourishing effect and anti-aging effect of Example 3 are all better than those of Comparative Examples 1-5; thus, it can be obtained that the present application adopts soybean polypeptide, ergothioneine, and palmitoyl pentapeptide-4 to synergize with each other, which can stimulate the strong absorption capacity of epidermal cells, and then supplemented with the synergistic effect of biosaccharide gum-1 and kaempferia root extract on the surface of the skin, further promoting more effective ingredients in the repair cream containing ergothioneine or stably fitting with epidermal cells to gradually exert their effects, or following soybean polypeptide, kaempferia root extract, ergothioneine, and palmitoyl pentapeptide-4 to be directly absorbed by the skin, making skin care more effective; in addition, it can be seen from the data of the positive control group and Comparative Examples 1-5 in Table 1 that only soybean polypeptide, ergothioneine, palmitoyl pentapeptide-4, biosaccharide gum-1 and kaempferia root extract synergize with each other to improve the absorption capacity of the skin to a certain extent.

It can be seen from the comparison of Example 4 and Example 3 and Example 5-6 that the absorption effect, moisturizing effect, whitening effect, nourishing effect and anti-aging effect of Example 4 are more excellent; It can be obtained from this analysis that the application adopts isopropyl myristate, large fruit blueberry seed oil, Indian garcinia seed fat, and polydimethylsiloxane as the compounded emollient, and the repair cream containing ergothioneine can be prompted to establish a more skin-friendly oily system, further improve epidermal cell permeability, promote skin for the absorption of the effective substance in the repair cream containing ergothioneine, and achieve the effect of lasting nourishing skin.

A comparison of Example 7 and Example 3 shows that the moisturizing effect of Example 7 is better than that of Example 3; from this analysis, it can be obtained that the repair cream containing ergothioneine, which is compounded by panthenol, hydrogenated starch hydrolysate, hydrolyzed red algae extract, and 5000-8000 Daltons of sodium hyaluronate, has a good long-lasting moisturizing effect, can replenish skin moisture from the endogenous source, inhibit the evaporation of skin moisture from the outer edge, and keep the skin in a state of saturated moisture.

A comparison between Example 8 and Example 3 and Example 9 shows that the tyrosinase inhibition effect of Example 8 is more excellent.
