Raw materials for skin rejuvenation and anti-wrinkle cosmetics

Cosmetic Raw Material that promotes cell proliferation and metabolism and antioxidant raw materials.

First, let's look at the Cosmetic Raw Materials that promote cell proliferation and metabolism ability.

1, cell growth factor

2, animal and plant extracts.

3, fruit acids.

In fact, it is divided into α-hydroxy acid and β-hydroxy acid. α-hydroxy acid, commonly known as fruit acid, is a class of hydroxy acids extracted from lemons, sugar cane, apples, lingonberries and other fruits, including dozens of substances. Hydroxyacetic acid and L-Lactic Acid are the most common. It is a class of small molecules that can be absorbed quickly. It can be used as a stripping agent, which is what we often call exfoliation. That in the end how to exfoliate it, it is penetrated into the stratum corneum of the skin, so that the skin aging stratum corneum in the inter-cellular adhesion weakened, accelerate the peeling of aging cells, and promote cell differentiation and proliferation, accelerate the speed of cell renewal, thereby improving the state of the skin, to achieve the role of anti-aging. The anti-wrinkle effect of fruit acid is related to the type and concentration of fruit acid, usually the smaller the molecular weight, the lower the pH, the higher the concentration, the better the effect of wrinkles, but also the greater the irritation. Generally, the concentration of fruit acids in cosmetics is 2%-8%, in fact, this concentration can not achieve the effect of wrinkle, but it can make the skin more glowing. Here we should mention hydroxyacetic acid, it is the smallest molecular weight fruit acids, the most penetrating ability to the skin, the most obvious effect, but also the strongest irritation.

4, collagen peptide.

Collagen is the main component in the connective tissue of the skin. Collagen is a large molecular protein, its molecular weight is more than 300,000, and can not be directly absorbed by the body. Collagen degradation or after enzyme treatment, it becomes collagen peptide, collagen peptide is collagen or gelatin by protease degradation process, can promote epidermal cell vitality, increase "nutrition", eliminate fine wrinkles in the skin.

5, Kaba elastin.

The structure of Kaba elastin is like elastin in the skin, like a spring, can be stretched. Research has proved that it stimulates the skin to synthesize elastin under the action of fibroblasts and improves the nature of skin elastin. In addition, it can form a translucent film on the skin surface, the skin has a protective and nourishing effect.
