Mechanism of Action
TETRAPEPTIDE-58 exerts its effects through a sophisticated dual mechanism. It incorporates the Cys-Gly-His-Lys motif, frequently recognized as GHK-peptide or Tripeptide-1, which effectively stimulates collagen proliferation, visibly enhancing skin texture and minimizing the appearance of wrinkles. Additionally, the Glutathion-like γ-Glu-Cys motif provides potent antioxidant capabilities, safeguarding dermal cells from oxidative stress and contributing to a brighter, more even skin tone. This combined action promotes improved skin firmness, elasticity, and optimized hydration.

The Formula
Formulation
Stability
TETRAPEPTIDE-58 exhibits good stability in aqueous solutions across a broad pH range of 3.0 to 10.5. For optimal peptide integrity and to mitigate potential deamidation and oxidation, a narrower pH range of 3.0-5.0 is recommended. For formulation, it should be integrated into an emulsion system after it has cooled to 40°C or lower. Raw peptide materials require refrigeration for long-term stability. Its water solubility is attributed to the presence of charged/polar amino acids in its sequence.
Safety
Safety Profile
TETRAPEPTIDE-58 itself has not undergone specific safety assessments by the CIR or SCCS. However, peptides generally demonstrate a high safety profile with low irritation potential. Amino acids, the foundational building blocks of peptides, are commonly recognized as safe (GRAS) by the FDA for direct food additives, supporting the overall favorable safety perception of this ingredient class.
