Science
Mechanism of Action
SH-TRIPEPTIDE-5 functions by activating the tissue growth factor (TGF-beta) within the skin, a crucial signaling pathway for stimulating the synthesis of Type I and Type II collagen and fibronectin. This directly encourages fibroblasts, the skin's collagen-producing cells, effectively mimicking the body's natural repair mechanisms. Additionally, it helps to safeguard existing collagen from degradation by inhibiting matrix metalloproteinases (MMP1 and MMP3) enzymes. The peptide also contributes to enhanced skin hydration by promoting water retention in the dermal layers and may help to reduce melanin production through a suggested decrease in tyrosinase activity.

The Formula
Formulation
Stability
For optimal stability, SH-TRIPEPTIDE-5 performs best within a pH range of 5.0 to 7.0. Refrigerated storage (2-8°C / 35-46°F) is recommended to maintain its integrity, and it is typically supplied without preservatives.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel assessed Palmitoyl Tripeptide-5 within a broader 'Palmitoyl Oligopeptides' group but found the collective terminology insufficient for a complete safety evaluation due to variations in amino acid sequences. Despite this, general safety assessments indicate this peptide is considered very safe and exceptionally well-tolerated, even for sensitive skin, carrying a low risk of adverse reactions. Suppliers are noted to operate in FDA-registered and cGMP/FDA compliant facilities.
