Technical Field

The invention belongs to the technical field of skin repair, and particularly relates to an intracellular active ingredient of fibroblast of human skin, a preparation method and application thereof.

Background

Human dermal fibroblasts are the main structural components constituting the dermis of the skin, are involved in aging and repair of the skin, can synthesize and secrete effective components, and have an important role in maintaining the stability of the skin. Collagen and many cell repair factors in the skin are mostly derived from fibroblasts, and have an important role in maintaining the activity of the skin.

The lack of a single active ingredient can often maintain the balance of the skin by adding corresponding cytokines or polypeptides. However, it is often empirical how to find the missing component, which does not result in a good repair of the skin. If several are missing, the skin is more difficult to replenish. More and more researches show that the maintenance effect of the plant essence on the skin activity is necessary to protect the skin and maintain and repair the skin by combining the intracellular effective components of the fiber cells with the plant essence.
