Topical peptides with established cosmetic dermatology research — GHK-Cu, Matrixyl derivatives, Argireline, and copper-tripeptide complexes.
Cosmetic & Copper Peptides (7)
Biotin-GHK (Biotinylated Copper Peptide)
Research-Grade
A biotinylated derivative of the copper-binding tripeptide GHK, combining the collagen-stimulating and wound-healing properties of GHK-Cu with biotin's keratin-supporting activity for enhanced hair and nail applications.
AHK-Cu (Copper Tripeptide AHK)
Cosmetic-Grade
A copper-binding tripeptide (Ala-His-Lys-Cu) studied for hair follicle stimulation, dermal papilla cell proliferation, and VEGF upregulation in hair growth applications.
GHK-Cu (Copper Tripeptide-1)
Cosmetic-Grade
A naturally occurring copper-binding tripeptide (Gly-His-Lys) with decades of cosmetic dermatology research in wound healing and skin remodeling.
GHK (Glycyl-Histidyl-Lysine)
Research-Grade
The base copper-binding tripeptide (Gly-His-Lys) found in human plasma and tissues — a precursor to GHK-Cu with intrinsic bioactivity in wound healing, gene modulation, and anti-inflammatory signaling.
KHK (Lys-His-Lys)
Research-Grade
A copper-binding tripeptide (Lys-His-Lys) that chelates Cu2+ ions to promote collagen synthesis, wound healing, and hair follicle stimulation as an alternative to GHK-Cu.
Palmitoyl-GHK (Pal-GHK)
Research-Grade
A lipidated derivative of the copper-binding tripeptide GHK, designed for enhanced skin penetration in topical anti-aging formulations.
Palmitoyl Tripeptide-1
Cosmetic-Grade
A lipopeptide signal peptide (INCI: Palmitoyl Tripeptide-1) used in Matrixyl and advanced skincare formulations to stimulate collagen I, III, and fibronectin synthesis via TGF-β activation.
