Science
Mechanism of Action
As a collagen tripeptide, TRIPEPTIDE-20 functions by stimulating the endogenous production of essential dermal components, including collagen, elastin, and hyaluronic acid. It demonstrates a protective effect against advanced glycated end product (AGE) accumulation and reduces the generation of reactive oxygen species in dermal fibroblasts. Furthermore, it modulates matrix metalloproteinase (MMP) activity, decreasing their induction while promoting an increase in collagen 1 levels. This peptide also fortifies the skin barrier by reducing transepidermal water loss (TEWL) and boosting skin hydration, thereby mitigating the appearance of wrinkles and potentially counteracting inflammation-accelerated degradation of skin's structural integrity.

Stability
TRIPEPTIDE-20 is stable within a pH range of 6.0 to 7.5. As a peptide, it is generally susceptible to degradation at elevated temperatures and requires protection from light exposure to maintain efficacy.
Safety
Safety Profile
TRIPEPTIDE-20 itself has not been specifically reviewed by the Cosmetic Ingredient Review (CIR) panel. However, structurally similar tripeptides, such as Tripeptide-1, are considered safe for cosmetic use at concentrations typically below 10 ppm, with a usage range extending to 30 ppm. Both oral and topical clinical studies involving collagen tripeptides, including Tripep20, have reported excellent safety profiles with no observed abnormal symptoms or adverse events. INCI Beauty further indicates a 'No penalty' rating for TRIPEPTIDE-20 across all categories.
