Science
Mechanism of Action
This synthetic peptide operates by mimicking natural collagen fragments, thereby activating the skin's inherent repair mechanisms. Its diminutive molecular size facilitates rapid absorption into deeper skin layers, where it serves as a foundational component for de novo collagen synthesis and upregulates hyaluronic acid production. This combined action is reported to enhance dermal water retention, improve skin elasticity and smoothness, ultimately mitigating visible lines and wrinkles for an overall improved complexion.

The Formula
Formulation
Stability
Peptides, including DIPEPTIDE-8 HCL, are prone to various degradation pathways such as deamidation, oxidation, hydrolysis, disulfide interchange, and racemization. Stability is influenced by pH, temperature, and buffer composition. While optimal dissolution often occurs at near-neutral pH (6-8), elevated concentrations of HCl (>10 mM in unbuffered solutions or >50 mM in buffered solutions) may compromise peptide thermal stability. For optimal preservation, peptide solutions are typically stored frozen in sterile buffers at pH 5-6, with repeated freeze-thaw cycles strictly avoided.

Safety
Safety Profile
A specific Cosmetic Ingredient Review (CIR) safety assessment for DIPEPTIDE-8 HCL is currently unavailable. Although general statements suggest peptides are safe ingredients, and other peptides (e.g., Acetyl Hexapeptide-8 Amide) have received CIR approval up to 0.005%, this information does not directly pertain to DIPEPTIDE-8 HCL. 'The Good Scents Company' indicates no identified GHS hazards, hazard statements, or precautionary statements; however, oral, dermal, and inhalation toxicity have been noted as 'Not determined'.
