Details

Properties

  • Firming: Strengthening the weakened cohesion between the dermis and epidermis by stimulating the synthesis of collagen and syndecan, a membrane protein that contributes to cell proliferation, cell migration and cell-matrix interactions;

  • Redensifying, regenerating: Increasing cellular density through stimulation of epidermal keratinocyte proliferation.

Usage

  • Facial Care(creams, serums, eye contours);

  • Haircare (shampoos, serums, styling foams);

  • Makeup (foundation).

Acetyl Tetrapeptide-11 is a synthetic signal peptide, produced by acetylation between acetic acid and Tetrapeptide-11. Peptides have the ability to penetrate deep into the skin layers to give various commands to skin cells. In particular, Acetyl Tetrapeptide-11 can increase the synthesis of the proteoglycan, syndecan-1, to strengthen the cohesion of the epidermis, improve the structural integrity of the dermo-epidermal junction (epidermal basal membrane), as well as the cohesion between the epidermis and the dermis, which is impaired by ageing, by stimulating the production of collagen by dermal fibroblasts. It also stimulates the proliferation of keratinocytes, thereby increasing cell density.
