Mechanism of Action
The precise mechanism of action for SR-TIGER POLYPEPTIDE-2 is extrapolated from studies on similar 'Tiger' peptides and the general biochemistry of polypeptides. Its likely actions include significant antioxidant activity, bolstering the skin's endogenous defenses against oxidative stress by enhancing antioxidant enzyme function and mitigating reactive oxygen species. Related peptides have been shown to facilitate wound healing by recruiting macrophages, stimulating the proliferation and migration of both keratinocytes and fibroblasts essential for re-epithelialization and tissue remodeling. Polypeptides generally also serve as signaling molecules, supporting the synthesis of collagen and elastin, and potentially reducing the enzymatic degradation of the extracellular matrix.

The Formula
Formulation
Stability
Polypeptides, including SR-TIGER POLYPEPTIDE-2, are generally water-soluble, particularly when processed with solubility-enhancing counterions like TFA salts. Optimal stability for polypeptides is typically pH-dependent, with a broad estimated range of pH 3.0 to 10.5. Some related 'tiger nut proteins' have demonstrated stability and solubility between pH 7.0 and 11.0.
Conflicts
- Strong acids or bases (potential for degradation)
- Proteases (enzymes that cleave peptide bonds, leading to inactivation)
- Heavy metals (can cause denaturation or aggregation)
- High temperatures (risk of degradation)
Safety
Safety Profile
Specific safety assessments from regulatory bodies such as CIR, SCCS, or FDA are not yet available for SR-TIGER POLYPEPTIDE-2. The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated broader categories of peptides, often concluding them safe for cosmetic use when appropriately formulated to be non-irritating. The safety of individual recombinant peptides is contingent upon their precise sequence, purity, and final concentration in a product.

Verdict
While research on related 'Tiger' peptides demonstrates significant potential for antioxidant activity, wound healing, and skin regeneration, direct clinical efficacy studies for SR-TIGER POLYPEPTIDE-2 itself are currently unavailable, warranting further specific investigation to confirm its precise benefits.
