Mechanism of Action
This peptide operates by engaging specific cellular signaling pathways, acting as an analog to human Keratinocyte Growth Factor (KGF). Its primary action is to accelerate the synthesis of vital dermal components, including collagen and elastin, leading to improved skin firmness and elasticity. RH-POLYPEPTIDE-3 also promotes epithelial cell proliferation and dermal cell adhesion, crucial for boosting regenerative processes such as wound healing. Furthermore, it aids in restoring the skin's protective barrier, optimizing moisture retention, and contributing to overall skin cell renewal. Emerging data suggest it may also offer anti-inflammatory benefits and contribute to skin brightening through melanin inhibition.

Stability
RH-POLYPEPTIDE-3 exhibits notable stability within formulations, maintaining its efficacy even when exposed to challenging conditions or combined with other active ingredients. However, peptide stability is generally pH-sensitive; deamidation rates increase significantly at alkaline pH, and oxidation processes accelerate above pH 7, suggesting optimal stability is achieved in slightly acidic to neutral environments.
Safety
Safety Profile
RH-POLYPEPTIDE-3 is generally considered a safe and well-tolerated ingredient within the cosmetics industry, with reports indicating a low incidence of irritation or allergic reactions. While it does not have a specific review status from major regulatory bodies such as CIR, SCCS, or FDA, cosmetic ingredients in the European Union are subject to comprehensive safety and efficacy regulations. Broader CIR assessments exist for peptide groups, though RH-POLYPEPTIDE-3 is not explicitly named. A patch test is recommended for all new product introductions, particularly for individuals with sensitive or allergy-prone skin. It is noted that specific toxicity data (oral, parenteral, dermal, inhalation) for SH-polypeptide-3 were undetermined in one safety information source.
