In recent years, with the gradual introduction of various natural concept cosmetics, the consumption demand of personal care products containing natural ingredients has continued to grow, and the position of plant extracts in cosmetics has become heavier and heavier, which has also led to various plant extracts. Further optimization in terms of safety and efficacy is required.
Beauty industry and CO2 extraction
Carbon dioxide supercritical extraction equipment has penetrated into the beauty industry.
With the expanding market of anti-aging cosmetics and the advantages of plant extracts, scientists are constantly looking for new natural plant extracts with anti-aging effect.
And the extraction of these anti-aging substances is aided by the supercritical carbon dioxide extraction equipment.
At present, many anti-aging substances have been found, and scientists have applied these substances to the preliminary research and development of anti-aging cosmetics.
Alpha-hydroxy acids, including glycolic acid, lactic acid, citric acid, malic acid and so on, come from lemon, apple, grape and other fruits. Alpha-hydroxy acid penetrates into the cuticle of the skin, weakens the bonding force between cells in the aged cuticle, speeds up cell renewal, promotes the detachment of dead cells, and achieves the purpose of improving skin condition.
Beta hydroxy acids
Beta hydroxy acids are substances extracted from natural plants (such as Liu Shupi, holly leaves and birch bark). As a new generation of fruit acid, its fat-soluble nature makes it easier to combine with oil-rich skin surface than traditional water-soluble fruit acid, and then slow-release the skin.
Papaya mercaptase is a kind of active factor with high biological activity. There are a large number of active mercapto groups in its molecular chain. It can effectively eliminate superoxide radicals and hydroxyl radicals in the body, reduce the content of lipid peroxide in the skin, and prevent the aging of muscle cells. Slow the aging process of skin.
