Science
Mechanism of Action
This peptide operates by stimulating the production of adiponectin within the skin, which consequently upregulates collagen synthesis, a process crucial for maintaining dermal elasticity and firmness. It further activates peroxisome proliferator-activated receptor Gamma coactivator 1a (PGC-1α) expression, enhancing the rate of adipogenesis and leading to increased lipid accumulation in subcutaneous preadipocytes. This dual action facilitates targeted volume growth, particularly in areas like the cheeks and décolleté, while simultaneously fortifying the dermal-epidermal junction (DEJ) and supporting the skin's natural repair mechanisms.

Key findings
- 01 In vitro studies demonstrated that concentrations of 0.1 mg/mL and 0.5 mg/mL increased PGC-1α expression in human subcutaneous preadipocytes by 25.6% and 61.1% respectively, enhancing subsequent lipid accumulation by 27.9% and 32.4%.
- 02 Reported to boost adiponectin production by up to 24%, leading to measurable improvements in skin firmness, elasticity, and a reduction in the appearance of fine lines and wrinkles.
- 03 A recommended formulation concentration of 2% (in a peptide solution) has been shown to stimulate adipogenesis, contributing to increased cheek volume and refined facial contours.

The Formula
Formulation
Stability
Optimal stability for the powder form requires storage at -20°C for up to three years, or at -80°C for one year when dissolved in a solvent, with protection from moisture. Formulated products are typically stable when stored between 2-8°C, with extended shelf life possible at -20°C.
Safety
Safety Profile
Acetyl Hexapeptide-38 has not undergone specific review by regulatory bodies such as CIR, SCCS, or FDA. While a related peptide (Acetyl Hexapeptide-8) was reviewed, this does not directly apply. Acetyl Hexapeptide-38 is generally recognized for its low irritancy and minimal known side effects; however, comprehensive safety data, particularly for higher concentrations, is not yet available from these specific panels.
