Science
Mechanism of Action
Tetrapeptide-44 functions as a signaling molecule, activating the skin's endogenous repair mechanisms. It exerts potent anti-inflammatory effects, effectively reducing irritation. This peptide simultaneously stimulates the production of vital collagen, strengthening the skin's structural integrity to minimize the appearance of wrinkles. Furthermore, it reinforces the skin's natural barrier function, which optimizes hydration levels and contributes to a smoother, more refined skin texture.

Stability
For optimal stability, Tetrapeptide-44 in solution should be prepared in sterile water under mildly acidic conditions and stored at -20°C. Lyophilized forms require storage at -20°C or in a dry environment, strictly avoiding repeated freeze-thaw cycles to preserve integrity.
Safety
Safety Profile
Tetrapeptide-44 is generally considered safe for cosmetic applications, demonstrating no skin toxicity and a capacity for irritation reduction. While adverse reactions are rare, patch testing is advisable. Official regulatory statuses from bodies like CIR, SCCS, or FDA are not yet established.
