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.
Beginner Basics
Plain-English guide to Palmitoyl Dipeptide-6
What it does
This is a small protein fragment attached to a fatty chain that researchers use in skincare products to boost collagen production in the skin. It's studied for reducing wrinkles and improving skin firmness and elasticity.
Typical dose
Research formulations typically contain 1-3% concentration, applied to clean, dry skin once or twice daily.
When to inject
This is a topical product (applied to skin, not injected), commonly used in morning and/or evening skincare routines.
Storage
Store the dry powder in a cool, dark place. Once mixed into a formulation, follow your product's storage instructions, typically in a cool location away from direct sunlight.
First-timer tip
Always apply to completely clean and dry skin for best absorption-moisture on the skin can reduce how well it works.

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
Storage and Stability
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.
