Science
Mechanism of Action
As a sophisticated synthetic signal peptide, Tetrapeptide-11 operates by directly stimulating the production of Syndecan-1, a crucial cell adhesion molecule, thereby enhancing cellular cohesion and strengthening the skin's inherent barrier function. Concurrently, it boosts Collagen XVII synthesis, reinforcing epidermal cohesion and the critical dermo-epidermal junction. This dual action, coupled with accelerated keratinocyte proliferation, results in improved cellular density, increased skin volume, and visible reduction in fine lines and wrinkles through enhanced regeneration.

Key findings
- 01 Clinical observations indicate that concentrations between 0.1% and 0.5% deliver optimal results for skin tightening and firming when incorporated into serums and creams.
- 02 Studies highlight significant improvements in overall skin structure across a broad concentration range from 0.000001% to 1.0%.
- 03 In vitro research demonstrates that even a low concentration of 0.00026% effectively increases Syndecan-1 and Collagen XVII levels within primary human keratinocytes.
