preparation example Construction

[0058] The method for preparing the above-mentioned stem cell skin care composition includes the following steps:

[0059] Step 1. The stem cell culture medium after culturing the stem cells, the freeze-thaw lysate of the cultured stem cells, serum albumin, mannitol, and Arg9 membrane-permeable peptide are mixed and freeze-dried to obtain a freeze-dried powder;

[0060] Step 2. Mix glycerin, sodium citrate, ellagic acid, vitamin E, and water uniformly to obtain a solvent;

[0061] Step 3. The lyophilized powder prepared in step 1 and the solvent solution obtained in step 2 are packaged separately, and then mixed during use.

[0062] The use method of the above-prepared stem cell skin care composition includes the following steps: mix the freeze-dried powder and the solvent uniformly, shake gently until the freeze-dried powder is completely melted, and then use it; morning and evening. First clean the skin with water or facial cleanser, take an appropriate amount of the product and gen...

Abstract

The invention discloses a stem-cell skincare composition. The stem-cell skincare composition comprises, by mass, 1-800 parts of component A and a component B, wherein the component A is prepared by stem cell extract, serum albumin, mannitol and an Arg9 cell-penetrating peptides through freeze drying, and the stem cell extract is the freeze-thaw lysate of a stem-cell culture medium after stem cell culture and cultured stem cells; the component B comprises glycerin, sodium citrate, ellagic acid, vitamin E and water; during use, the component A is mixed with the component B. The invention further discloses preparation and application methods of the stem-cell skincare composition. The stem-cell skincare composition has the advantages that various factors of the stem-cell skincare composition have a synergic effect, and the factors can effectively penetrate the skin to enhance the metabolism of the skin from the deep layer, delay skin aging, whiten the skin, prevent or improve skin spots and wrinkles, remove acne and prevent allergy.

Description

Technical field [0001] The present invention relates to the technical field of skin care products, in particular to a stem cell skin care composition and a preparation method and use method thereof. Background technique [0002] With the continuous improvement of living standards, people pay more and more attention to health, especially skin maintenance. Skin tissue is the largest tissue organ of the human body, covering the surface of the human body, blocking the harmful effects of all harmful substances in nature on the living organism. However, with the increase of age, the function of skin tissues and organs gradually ages. From an aesthetic point of view, it seriously affects people's enthusiasm for life; from a physiological point of view, it affects the effective protection of human internal organs. So a variety of beauty and skin care products came into being. [0003] Stem cells are cells with proliferation and differentiation potential, have the ability to self-renew an...
