Description

  The present invention relates to a collagen production promoter having an action of activating collagen production by fibroblasts, a skin cosmetic to which skin aging prevention / improvement action is given, and a food and drink having a beauty action (beauty food and drink ).

  The dermis and epidermis of the skin are composed of epidermal cells, fibroblasts and an extracellular matrix such as collagen that is outside these cells and supports the skin structure. In young skin, these skin tissues interact with each other to maintain moisture retention, flexibility, elasticity, etc., and the skin is maintained in a fresh and supple state. .

  However, when the influence of certain external factors such as ultraviolet rays, drastic drying of air, excessive skin washing, etc. or aging progresses, the production amount of collagen, which is a major component of the extracellular matrix, decreases. Reduces elasticity due to cross-linking. The influence of external factors and a decrease in the proliferation rate of fibroblasts with aging also cause a decrease in collagen production. As a result, the skin's moisturizing function and elasticity are lowered, and the keratin begins to exfoliate abnormally, so that the skin loses its tension and gloss, and exhibits aging symptoms such as roughness, wrinkles and dullness.

  Thus, changes accompanying skin aging, i.e., wrinkles, dullness, disappearance of texture, decreased elasticity, etc. include reduction / degeneration of dermal matrix components such as collagen, and decrease in the proliferation rate of fibroblasts. Is involved.

  In recent years, the involvement of matrix proteases has been pointed out as a factor for inducing the change. Among the matrix proteases, collagenase, that is, MMP-1 (matrix metalloprotease) is known as an enzyme that degrades type I and III collagen, which is the main component of the dermal matrix of the skin. It is thought that it increases greatly due to UV, contributes to decrease / denaturation of collagen due to ultraviolet rays, and is a major factor such as skin wrinkle formation.
