Science
Mechanism of Action
As a signal peptide, Hexapeptide-7 (also referred to as Heptapeptide-7 or an HB-107 fragment) operates by stimulating the proliferation and migration of keratinocytes, the primary cells of the epidermis. It up-regulates genes associated with cell division, growth factors, and extracellular matrix components, thereby initiating collagen synthesis. This peptide is understood to activate the skin's innate repair mechanisms, promoting regeneration and reinforcing the dermal structure.

Key findings
- 01 A clinical study involving 32 women with a mean age of 54 demonstrated noticeable improvements in forehead wrinkles and overall skin texture following topical application of this peptide fragment.
- 02 Beyond structural improvements, Hexapeptide-7 is noted for its collagen-boosting capabilities and its ability to enhance skin radiance and brightness through the encouragement of healthy cellular turnover, specifically targeting fine lines and expression wrinkles.

Dusting Analysis
Current research data does not indicate Hexapeptide-7 is commonly used at sub-efficacious percentages for marketing purposes. Specific efficacy concentrations are not widely published, preventing a precise dusting threshold assessment.
The Formula
Formulation
Stability
Peptides generally exhibit sensitivity to degradation influenced by pH, temperature, moisture, and bulking agents. For optimal stability, it is advised to incorporate Hexapeptide-7 into formulations during the final phase, at temperatures maintained below 45 °C.
Safety
Safety Profile
Hexapeptide-7 and its acetylated form lack a specific safety assessment from the Cosmetic Ingredient Review (CIR) panel. While CIR has evaluated other hexapeptides, direct review for Hexapeptide-7 is pending. Regulatory information for SpecPed® AH7P (Acetyl Hexapeptide-7) is also currently unavailable per UL Prospector.
