Skin & Hair Peptides
Peptides researched for skin health, collagen production, hair growth, and cosmetic applications.
About Skin & Hair Peptides
Skin and hair peptides are among the most widely used in cosmetic applications. GHK-Cu (copper peptide) is extensively researched for wound healing, collagen stimulation, and anti-aging effects. Other notable peptides include various collagen-stimulating peptides, hair growth peptides, and wound healing compounds. Many of these are available in topical formulations and are used in skincare products, while some are administered via injection for systemic effects.
All Skin & Hair Peptides (7)
GHK-Cu
ResearchAlso: Copper Peptide, Glycyl-L-histidyl-L-lysine copper
A naturally occurring copper-binding peptide found in human plasma, saliva, and urine. Widely used in skincare for its wound healing and anti-aging properties.
Snap-8
ResearchAlso: Acetyl Octapeptide-3, SNAP-8
A cosmetic peptide that reduces wrinkles by inhibiting muscle contraction. Often called 'Botox in a bottle' though mechanism differs from actual botulinum toxin.
Argireline
ResearchAlso: Acetyl Hexapeptide-3, Acetyl Hexapeptide-8
A popular cosmetic peptide that reduces facial wrinkles by inhibiting neurotransmitter release. One of the most widely used peptides in anti-aging skincare.
Matrixyl
ResearchAlso: Palmitoyl Pentapeptide-4, Pal-KTTKS
A collagen-stimulating peptide widely used in anti-aging skincare. One of the first peptides proven to reduce wrinkles by stimulating collagen synthesis.
Matrixyl 3000
ResearchAlso: Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7
An advanced version of Matrixyl combining two peptides for enhanced anti-aging effects. Targets both collagen production and inflammation.
Copper Peptide AHK-Cu
ResearchAlso: Tripeptide-3, Ala-His-Lys Copper
A copper-binding tripeptide primarily used for hair growth stimulation. Shows promise for both hair loss prevention and scalp health.
Melanotan I
FDA ApprovedAlso: Afamelanotide, Scenesse
A 13-amino acid synthetic analog of α-MSH that stimulates melanin production. FDA-approved (as Scenesse) for treating phototoxicity in patients with erythropoietic protoporphyria (EPP). More selective than Melanotan II with fewer side effects.
Frequently Asked Questions About Skin & Hair Peptides
What is GHK-Cu?
GHK-Cu is a naturally occurring copper peptide found in human plasma. It stimulates collagen and elastin synthesis, promotes wound healing, and has anti-inflammatory and antioxidant properties. It's widely used in skincare products and researched for injectable applications.
Can peptides help with hair loss?
Several peptides are being researched for hair growth, including copper peptides and various growth factors. While some show promise in stimulating hair follicles and prolonging the growth phase, more research is needed to establish efficacy.
Are cosmetic peptides effective?
Many cosmetic peptides have research supporting their effects on collagen production, skin elasticity, and wound healing. GHK-Cu has particularly strong evidence. However, efficacy depends on formulation, concentration, and delivery method.
