Cosmetics are very popular commodities. Their consumption follows the social trend and has distinct characteristics of the times. With the deepening of medical research, consumers are more cautious about using cosmetics made of chemical compounds. In recent years, the production of cosmetics has started to naturalize raw materials, forming a world upsurge in the development of natural resources. With the improvement of the quality of life with the economic development, how to delay the aging process has become the hottest topic. Everyone hopes to have healthy, beautiful and young skin. What they need is skin care products that can not only protect the skin, but also help delay skin aging. The aging of the social population and the deterioration of the environment will lead to the aging of people's skin, which is becoming more and more serious. People will increasingly need long-term, efficient regulatory and preventive skin care products. According to the free radical theory of aging, excess active oxygen free radicals in the body react with unsaturated fatty acids to produce malondialdehyde and other substances. MDA combines with proteins on the cell membrane to produce brown pigment, which precipitates on the skin and becomes various color spots. Free radicals can also make the collagen fibers and elastic fibers in the skin cross-linked, denatured, brittle and lose elasticity. When the water in the skin is insufficient, it is easy to break the elastic fibers and form wrinkles. Moisturizing is the most important part of skin maintenance. It aims to keep certain moisture in the skin by preventing the loss of moisture in the skin and absorbing moisture from the external environment. At the same time, many nutrients are channeled to the skin through water. Moisturizing is a basic function of skin care products. Maintaining skin moisture can improve skin elasticity and smoothness, and is an important measure to ensure skin health and delay aging.

    Bamboo is a perennial evergreen plant in the Gramineae family. It is one of the most valuable natural products in the world. China is located in the center of bamboo distribution in the world. It is one of the major bamboo producing countries in the world and is known as the "Kingdom of bamboo". The outer epidermis of bamboo is called Zhuru in traditional Chinese medicine. An ingredient called bamboo essence can be extracted from Zhuru. Bamboo essence has remarkable moisturizing effect, which is slightly lower than that of hyaluronic acid, but stronger than that of hyaluronic acid in maintaining elasticity. It also inhibits tyrosinase, which produces melanin. At the same time, bamboo essence is safe and non-toxic, with obvious moisturizing, whitening and anti wrinkle effects. It can be used in the development of cosmetics and health food. Bamboo essence mainly contains flavonoids, phenolic acids, terpenoids, polysaccharides and other main components, of which flavonoids mainly include Carex glycoside, isocarex glycoside, Vitexin and isovitexin. amongIsoerythrosideIt has good free radical scavenging ability, anti-oxidation ability, bacteriostasis and anti-corrosion ability. It is one of the main components of total flavonoids in bamboo essence.

      Because China is rich in bamboo production, the extracts from various parts of bamboo can be developed and utilized, and they are safe, non-toxic and natural health care. Therefore, bamboo has excellent development and application prospects, and can create considerable economic benefits.
