Peptide index

GHK-Cu's less-famous cousin, used almost entirely in scalp serums to push VEGF from dermal papilla cells and improve follicle blood supply.

Cosmetic, Skin & Hair

A SNAP-25 mimic applied to the skin to blunt micro-contractions in expression lines — real but modest, and nothing like an injection of botulinum toxin.

Cosmetic, Skin & Hair

GHK with a biotin group attached, used in scalp serums to strengthen the follicle's anchoring in the dermis and reduce hair fall.

Cosmetic, Skin & Hair

The bacterial neurotoxin that actually paralyses mimetic muscle — not a peptide in any useful sense, but the benchmark every topical 'peptide Botox' is measured against and loses to.

Cosmetic, Skin & Hair

A hair complex pairing a matrix-strengthening tetrapeptide with a red clover isoflavone that inhibits 5-alpha-reductase, attacking both the follicle's anchoring and its DHT exposure.

Cosmetic, Skin & Hair

A non-cytotoxic tyrosinase inhibitor developed as a hydroquinone alternative, with real published melasma data behind it — unusual for this category.

Cosmetic, Skin & Hair

An anti-puffiness tetrapeptide for under-eye bags that works on fluid retention and capillary leak rather than on wrinkles or pigment.

Cosmetic, Skin & Hair

The best-evidenced cosmetic peptide there is: a copper-carrying tripeptide that pushes fibroblasts to rebuild collagen, elastin and glycosaminoglycans while dialling down matrix breakdown.

Cosmetic, Skin & Hair

A four-part complex for dark circles that chelates leaked iron, speeds bilirubin clearance and thickens the thin under-eye skin that lets the pigment show through.

Cosmetic, Skin & Hair

A yeast-fermentation-derived hexapeptide marketed as an anti-senescence active for dermal firmness rather than as a wrinkle-specific ingredient.

Cosmetic, Skin & Hair

A leu-enkephalin analogue applied topically to quiet acetylcholine release from the nerve side of the junction, sold as the presynaptic partner to Argireline.

Cosmetic, Skin & Hair

A fatty-acid-tagged collagen fragment that tricks fibroblasts into thinking the matrix has been damaged, so they lay down new collagen and fibronectin.

Cosmetic, Skin & Hair

Two matrikine lipopeptides sold as one ingredient: one rebuilds matrix, the other suppresses the inflammatory and glycation damage that tears it down.

Cosmetic, Skin & Hair

A lipopeptide marketed for deeper set wrinkles because it stimulates six matrix constituents at once, including the basement-membrane proteins the other Matrixyls ignore.

Cosmetic, Skin & Hair

A competitive alpha-MSH blocker that shuts down the signal telling melanocytes to make pigment, rather than poisoning the tyrosinase enzyme downstream.

Cosmetic, Skin & Hair

The mirror image of Melanostatine: an alpha-MSH mimic that switches MC1R on to deepen pigment and improve the skin's own UV defence, without an injection.

Cosmetic, Skin & Hair

GHK with a fatty tail bolted on so it actually penetrates the stratum corneum — copper-peptide-style collagen signalling without the copper or the blue stain.

Cosmetic, Skin & Hair

A tripeptide aimed at sagging rather than wrinkles, marketed for reducing progerin and inhibiting the elastase that dissolves the skin's elastic scaffold.

Cosmetic, Skin & Hair

A cell-penetrating peptide that pries the Wnt brake CXXC5 off Dishevelled, restarting follicle neogenesis in mouse skin — currently the most interesting preclinical hair compound in the peptide world.

Cosmetic, Skin & Hair

A longer Argireline with two extra residues that bind the SNARE complex more tightly, usually formulated alongside its shorter parent.

Cosmetic, Skin & Hair

A synthetic mimic of temple viper venom that blocks the muscle-type nicotinic acetylcholine receptor, working on the receiving side of the junction instead of the nerve side.

Cosmetic, Skin & Hair

A thrombospondin-1 mimic that converts latent TGF-beta into its active form, driving collagen synthesis through the body's own wound-repair switch.

Cosmetic, Skin & Hair

The actin-sequestering repair peptide applied to skin and scalp rather than injected, on the strength of mouse data showing it activates hair follicle stem cells.

Cosmetic, Skin & Hair

GHK without the copper — used when copper's blue colour or its reaction with vitamin C and other reducing actives would wreck the formula.

Cosmetic, Skin & Hair

A curare-style competitive blocker at the muscle nicotinic receptor, sold for fast surface smoothing rather than long-term collagen change.

Cosmetic, Skin & Hair

A zinc-activated thymic nonapeptide applied to the scalp, and one of the very few experimental hair peptides that has actually been tested on human heads.
