Retinyl propionate CAS:7069-42-3

1. Promote collagen production in dermal fibroblast cells: The reduction of collagen will cause the skin to lose elasticity and form wrinkles.

2. Promote the deposition of mucopolysaccharides such as hyaluronic acid between epidermal keratinocytes: With age, the content of hyaluronic acid in the skin decreases, leading to epidermal dehydration and the formation of wrinkles.

3. Promote and inhibit the activity of MMP in the dermis: MMP (matrix metalloproteinases) can promote the breakdown and denaturation of elastin or collagen, ultimately leading to the formation of wrinkles.

4. Promoting the repair of damaged elastic fibers: Elastic fibers refer to very fine elastic protein fibers that run vertically from the basement membrane, and their breakage and decomposition will cause the skin to lose elasticity and form wrinkles.

5. Promote the proliferation of epidermal cells: Microscopic aging of cells directly leads to the aging of the skin on the surface. Promoting cell division and proliferation will accelerate the shedding of old cells in the epidermal stratum corneum, making people look much younger.
