The first generation is skin care products in the era of fine chemistry, which are mainly composed of animals, plants, petroleum and minerals, and compounded with chemical auxiliary materials by adding emulsification or stirring. Its main function is to regulate the acid-base balance, moisturize and cover the skin, but its disadvantage is that it irritates and hurts the skin and is harmful to health, such as water, milk and cream traditionally sold.
The second generation is a skin care product in the biomedical era, which is mainly made of biological and medicinal plant extracts through emulsification and stirring. They contain a lot of active substances similar to human skin. Their main function is to protect skin moisture and improve the nutritional energy on the skin surface. The disadvantage is that the skin is in good condition when used, and the skin will recover immediately after stopping using it, which is easy to form addiction. In addition, too much nutrition will destroy the original microecological balance of the skin and fail to achieve the real beauty purpose.
The third generation is skin care products in the ecological era. Using microecological engineering technology, microecological skin probiotics are applied to the daily skin care process, which can adjust the microecological balance of human skin and inhibit or kill demodex folliculorum. It is common in skin and facial skin, which affects beauty and restores an emulsified lipid membrane (ecological membrane is also called sebum membrane) formed by microorganisms involved in metabolism. Promote the production of various enzymatic and non-enzymatic antioxidants in the skin, accelerate the shedding of epidermal cells, and maintain the skin's absorption of water and nutrients, thereby improving skin vitality, rebuilding tension and elasticity, delaying aging, and achieving the purpose of restoring the natural ecology and bodybuilding of the skin. The disadvantage is that most of these products are live bacteria preparations, and the number and types of microbial bacteria are strictly regulated in cosmetics inspection in various countries. The laws and regulations of microecological products are in the original blank, so it is difficult to popularize these products on a large scale. At present, these products are only sold in high-end personalized and antibacterial drugs.
In recent years, with the rapid development of microecology, the important role of human microecosystem in health and longevity has been continuously confirmed by authoritative research. Not only the high incidence of digestive diseases such as irritable bowel disease, inflammatory bowel disease and intestinal cancer, but also the high incidence of metabolic diseases such as diabetes and obesity have been confirmed to be closely related to the imbalance of human microecology. The research of microecology is considered to bring a revolution to health care.
Ecological skin care products will be the focus of research and development of skin care products. Ecological skin care products are the development trend of skin care products industry, and human beauty skin care products will be upgraded again after they have evolved from the chemical age to the biological age. This is the evolution of civilization in which human beings know nature and themselves.
The human body is an open system, and we exchange these substances and information with nature all the time. From a broad ecological point of view, the human body has also formed a complete ecosystem. Due to the close cooperation between organs and tissues and the close communication with air, water, microorganisms, energy and other resources in the external environment, human beings can live endlessly.
Human skin has the ability to maintain its own microecological stability, and there are biological or antagonistic effects between flora. If the host's skin, environment and flora are in an uncoordinated pathological state, that is, microecological imbalance, for example, the number of micrococcus pigmentosum and conditionally pathogenic gram-negative bacilli increases and the isolation rate is high, it will cause pathological damage to the skin, resulting in pigmentation and chloasma.
The imbalance of skin ecology will lead to various skin problems, such as eczema, chloasma, acne, baldness, allergy, folliculitis, dry skin, wrinkles, hormone face, cosmetic-dependent dermatitis, fungal infection, body odor, beriberi and so on.
