Use with Luxe Potion in equal parts when microneedling at .5 depth. These peptides are signal molecules, not exfoliants or actives that damage tissue, so they benefit from enhanced penetration without increasing injury risk. Perfect for application at full strength after microneedling and here's why:
Palmitoyl Tripeptide-1 & Palmitoyl Tripeptide-5
Fibroblast signaling + collagen stimulation. Mimics a fragment of collagen. Signals fibroblasts to increase collagen production. Helps improve firmness and reduce the look of fine lines. Often positioned as a “pro-collagen” peptide.
Microneedling helps them reach viable epidermis/upper dermis where they actually work
Palmitoyl Tetrapeptide-7
Reduces post-needling inflammatory cytokines
Helps control redness, swelling, and collagen degradation
This combination supports repair, not trauma, which is exactly what you want post-needling.
 
Why these peptides are used together: Tripeptide-1 + Tripeptide-5 = collagen stimulation. Tetrapeptide-7 = inflammation control. Together they’re often marketed as a “Matrixyl-type” peptide complex because they address both building collagen and preventing its breakdown.
