PALMITOYL TRIPEPTIDE-5.

Valuable CAS - / SKIN CONDITIONING

Palmitoyl Tripeptide-5 is a potent synthetic peptide engineered to deeply penetrate the skin, actively stimulating the synthesis of vital structural proteins like collagen and elastin. It works by activating key growth factors and mimicking natural reparative processes, effectively targeting visible signs of aging for improved skin structure and resilience.

Summary

Skin-Conditioning Anti-aging Boosts Collagen Improves Skin Texture Firming Elasticity-Enhancing Wrinkle-Reducing Pore-Refining

Science

Mechanism of Action

This synthetic peptide operates by penetrating the deeper layers of the skin to activate the Transforming Growth Factor-beta (TGF-β) growth factor, a critical component for the synthesis of collagen types I and II, as well as fibronectin. It directly stimulates fibroblasts, the skin's collagen-producing cells, and mimics a natural reparative protein, thereby promoting skin regeneration, firmness, and elasticity. Furthermore, Palmitoyl Tripeptide-5 boosts collagen I and elastin production while simultaneously inhibiting matrix metalloproteinases (MMPs), enzymes responsible for collagen degradation. This multi-faceted action supports the extracellular matrix, leading to smoother, more youthful-looking skin. Preliminary evidence also suggests it may help inhibit melanin production by reducing tyrosinase activity.

Dusting Analysis

Not commonly dusted

Clinical studies demonstrate efficacy at concentrations ranging from 1% to 2.5%, which aligns with typical cosmetic use levels reported as 1-3% as a blend. This indicates the ingredient is generally incorporated at functionally effective concentrations, rather than being merely 'dusted'.

Stability

For optimal stability, formulations should maintain a pH between 4.0 and 7.0. This ingredient should be incorporated into the water phase during the cool-down phase of formulation, ensuring temperatures remain below 40 °C (104°F).

Conflicts

  • Potent exfoliating acids (e.g., AHAs/BHAs) may diminish peptide efficiency, particularly in skin that is not well-tolerant to exfoliation.

Safety

Safety Profile

CIR Status
Safe as used
Max tested
3%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has determined Palmitoyl Tripeptide-5 to be safe in its current cosmetic uses and concentrations. It is highly regarded as a very safe and well-tolerated active ingredient, even for sensitive skin types, and typically does not cause irritation. However, some literature from EWG notes limited evidence of toxicity, irritation (at high doses in animal studies, equivocal in human occupational studies), biochemical/cellular changes (at moderate/high doses in animal studies), and immune or allergenic effects (at moderate doses in animal studies). Typical cosmetic use levels range from 1–3% as a blend.
