Science
Mechanism of Action
This synthetic peptide functions as a specific agonist for delta opioid receptors within the skin, influencing these receptors which are intrinsically linked to inflammatory and stress responses. By moderating their activity, Hexapeptide-48 HCl effectively reduces skin inflammation, enhances epidermal differentiation, and strengthens barrier function. This multifaceted action mitigates chronological stress aging, environmental damage (such as from cigarette smoke), and addresses the root causes of hyperpigmentation, fine lines, and deeper wrinkles. Additionally, it acts as a skin conditioning and protective agent, promoting regeneration, repair, and optimizing moisture retention for superior hydration.

Key findings
- 01 Clinical observations indicate that concentrations between 0.1% and 2% significantly reduce skin inflammation, improve epidermal differentiation, and enhance skin barrier function. It aids in repairing damaged skin by decreasing Transepidermal Water Loss (TEWL), leading to increased hydration and a reduction in wrinkles, particularly around the perioral and ocular areas.
- 02 For optimal efficacy, a 1% concentration is recommended when Hexapeptide-48 HCl is incorporated into a water-based blend.
