Problems solved by technology

[0003] However, simply using stem cell extracts to achieve cosmetic effects through injection is slow, and the injection method requires professionals to use medical devices in designated places, which limits its audience. Exosome essence products are also rare, so the development of an essence containing stem cell exosomes with moisturizing, whitening and anti-oxidant properties can solve this problem

Abstract

The invention discloses essence containing stem cell exosomes, and belongs to the technical field of cosmetic preparation. The essence comprises the following raw materials in parts by weight: 10-13 parts of skin stem cells, 15-20 parts of sodium hyaluronate, 6-8 parts of denatured ethanol, 2-6 parts of hydroxyethyl piperazine ethanesulfonic acid, 5-8 parts of modified collagen, 4-6 parts of organic silicon wax, 3-5 parts of octyldodecanol, 2-4 parts of ascorbyl glucoside, 1-3 parts of ammonium polyacryloyldimethyl taurate and 10-12 parts of deionized water. The invention also discloses a preparation method of the essence. According to the skin stem cell exosome essence, the skin stem cell exosome is used in the essence, the water locking capacity of the essence on the skin can be greatly improved, the fine and smooth degree of the skin can be improved, and meanwhile, the modified collagen is rich in collagen, chitosan and camellia seed extracts, so that the skin stem cell exosome essence not only has high nutritional value, but also has the characteristics of moisture resistance, oxygen resistance, bacteria resistance, oxidation resistance and moisture retention.

Description

technical field [0001] The invention belongs to the technical field of cosmetic preparation, and relates to an essence containing stem cell exosomes and a preparation method thereof. Background technique [0002] Skin is the largest organ of the human body. It covers the body surface and is composed of epidermis, dermis, subcutaneous tissue and appendages. It plays an important role in resisting microbial invasion, ultraviolet radiation, preventing water loss, regulating body temperature and maintaining human appearance. important role. In recent years, the use of living cells for beauty has become a hot spot in the market, especially the use of stem cells. Through direct injection on wrinkles, scars and scars, living cells can differentiate and grow in the skin, filling and repairing the skin. [0003] However, simply using stem cell extracts to achieve cosmetic effects through injection is slow, and the injection method requires professionals to use medical devices in des...
