Palmitoyl Dipeptide-6
A synthetic dipeptide conjugate with a palmitic acid chain that stimulates collagen synthesis and improves skin barrier function for anti-aging and skin elasticity applications. Used topically in cosmetic formulations.
Research Status
Limited Clinical Data
For research purposes only. Not approved for human use. Not medical advice.
Research Areas
Side Effects
May occur in sensitive individuals or with high concentrations (>3%). Typically resolves within 24–48 hours. Reduce frequency to 1x daily if irritation persists.
Possible in individuals with known sensitivity to peptides or cosmetic excipients. Perform patch test on small area before full-face application.
Self-resolving within minutes. Does not indicate harm; may reflect increased blood flow to the area.

Reconstitution Guide
Do not use saline or bacteriostatic saline — use only bacteriostatic water for reconstitution
Do not shake the vial vigorously; gentle swirling prevents peptide degradation
Discard immediately if the solution appears cloudy, discolored, or contains visible particles
Use within 30 days of reconstitution when stored at 2–8°C
Do not freeze the reconstituted solution; freezing may denature the peptide
Use the PeptideVolt reconstitution calculator for your exact concentration
Molecular and Pharmacological Data
Palmitoyl Dipeptide-6 is a lipophilic dipeptide that penetrates the stratum corneum and activates fibroblast signalling pathways to upregulate collagen I and III synthesis. The palmitic acid moiety enhances skin penetration and cellular uptake, promoting dermal remodelling and improving skin structural integrity and elasticity.
Fibroblast Activation & Collagen Synthesis
The peptide binds to cell surface receptors on dermal fibroblasts, triggering intracellular signalling cascades that increase expression of pro-collagen genes and promote extracellular matrix deposition.
Skin Barrier Enhancement
Stimulates production of structural proteins and lipids that strengthen the dermal–epidermal junction and improve transepidermal water loss (TEWL) reduction.
- Palmitoyl conjugation increases lipophilicity and skin penetration compared to unconjugated dipeptides
- In vitro studies demonstrate dose-dependent increases in collagen I mRNA expression in human fibroblasts
- Effects are cumulative with repeated topical application over 4–12 weeks
