Peptides
17 peptide ingredients explained in plain English.
Acetyl Hexapeptide-8 Acetyl Hexapeptide-8 A neuropeptide marketed as a topical alternative to muscle-relaxing injections. Softens expression lines around the eyes and forehead. Acetyl Tetrapeptide-3 Acetyl Tetrapeptide-3 A four-amino-acid peptide marketed for hair growth and density. Targets the dermal papilla at the root of each follicle. Acetyl Tetrapeptide-5 Acetyl Tetrapeptide-5 A four-amino-acid peptide developed for the eye area. Reduces puffiness, dark circles, and crow's feet. Biotinoyl Tripeptide-1 Biotinoyl Tripeptide-1 A small peptide attached to a biotin (vitamin B7) tail. Used in scalp serums for hair density and follicle support. Copper Tripeptide-1 (GHK-Cu) Copper Tripeptide-1 A small naturally-occurring peptide complexed with copper. Supports wound healing, collagen synthesis, and barrier repair. Dipeptide Diaminobutyroyl Benzylamide Diacetate Dipeptide Diaminobutyroyl Benzylamide Diacetate A small synthetic peptide modeled after a fragment of snake venom. Marketed as a topical muscle-relaxing wrinkle softener. EGF (Epidermal Growth Factor) sh-Oligopeptide-1 A recombinant human growth factor that signals skin cells to proliferate and repair — one of the most potent (and expensive) anti-aging peptides available. GHK-Cu (Copper Tripeptide-1) Copper Tripeptide-1 A copper-bound tripeptide with strong evidence for wound healing, collagen remodeling, and hair growth stimulation — one of the most-studied peptides in cosmetic science. Palmitoyl Hexapeptide-12 Palmitoyl Hexapeptide-12 A six-amino-acid signal peptide developed as a refinement of the original anti-wrinkle pair. Targets fine lines and barrier proteins. Palmitoyl Pentapeptide-4 Palmitoyl Pentapeptide-4 A signal peptide modeled on a collagen fragment. Prompts skin to make more collagen, elastin, and fibronectin. Palmitoyl Tetrapeptide-20 Palmitoyl Tetrapeptide-20 A lipopeptide for hair greying support. Stimulates melanin production in hair follicles by reactivating pigment-producing cells. Palmitoyl Tetrapeptide-7 (standalone) Palmitoyl Tetrapeptide-7 A four-amino-acid signal peptide with a calming, anti-inflammatory effect. Reduces redness, puffiness, and stress-induced skin response. Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7 A pair of signal peptides best known under their trade name as the original anti-wrinkle peptide blend. Targets fine lines and skin firmness. Palmitoyl Tripeptide-38 Palmitoyl Tripeptide-38 A broader-spectrum signal peptide marketed as a multi-collagen booster. Targets several skin matrix proteins at once. Pea Peptide Pisum Sativum Peptide A plant-derived peptide from peas that targets skin firmness and elasticity as a vegan alternative to animal-sourced collagen boosters. sh-Oligopeptide-1 (EGF) sh-Oligopeptide-1 A 53-amino-acid growth factor produced via biotechnology. Powerful skin-cell signal for repair and renewal — with significant safety caveats. Tripeptide-1 Tripeptide-1 A short three-amino-acid signal peptide that supports collagen and elastin production. The non-copper version of GHK.
