A synthetic dipeptide-cetyl ester (trade name Lumiskin/Calmosensine) that modulates the skin's endorphin pathway to deliver soothing and anti-aging benefits.
A synthetic seven-amino-acid peptide (Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala; trade name Fensebiome™) that acts as a microbiome-modulating active, strengthening the skin's barrier and defence against pathogens rather than acting on neuromuscular SNARE pathways.
A synthetic dipeptide derivative with a hexanoyl and acetyl modification. Has melanogenesis-inhibiting properties for skin brightening. Used in Ishizawa's urea face cream.
A synthetic hexapeptide (trade name Melitane) that activates the alpha-MSH receptor pathway to stimulate melanin synthesis and support an even skin tone.
A biomimetic hexapeptide that stimulates lipid accumulation in dermal adipocytes (fat cells). Used in anti-aging products to restore facial volume and firmness. Found in Minon's aging care products.
A synthetic six-amino-acid peptide used in premium Korean skincare formulas for its skin-conditioning and anti-aging properties. Distinct from Acetyl Hexapeptide-8 (Argireline) and from Acetyl Heptapeptide-4 (Fensebiome).
An 8-amino-acid acetylated peptide (trade name SNAP-8), the extended version of Acetyl Hexapeptide-3. Acts as a neurotransmitter inhibitor that relaxes facial expression muscles, providing a topical anti-wrinkle mechanism similar to botulinum toxin. Used in premium K-beauty peptide ampoules.
A synthetic signaling tetrapeptide that upregulates syndecan-1 and Collagen XVII expression in keratinocytes, supporting skin barrier cohesion and firmness.
Acetyl Tetrapeptide-2 (ac-KDVY; trade names Peptigravity, Uplevity, Thymulen-4 by Lipotec/BASF) is a biomimetic signal peptide derived from the thymopoietin hormone sequence. Its principal mechanism is upregulation of the elastin assembly pathway — specifically FBLN5 and LOXL1, proteins required to cross-link tropoelastin into mature elastic fibers — alongside collagen I/IV/VI/XIV stimulation and MMP inhibition. Peer-reviewed AFM studies (PMC6208634) confirm dose-dependent increases in keratinocyte cell stiffness and upregulation of ACTN1, ITGB4, and COL17A1. Used at 0.005–2% in serums, ampoules, and eye creams targeting firmness and skin density loss.
A peptide marketed to relax expression lines.
A signaling peptide that supports skin repair and firmness.
A synthetic dipeptide that acts as a reversible antagonist at muscular nicotinic acetylcholine receptors, reducing repetitive facial muscle contractions to smooth expression lines.
A synthetic dipeptide of two glycine residues (glycylglycine) used as a skin- and hair-conditioning agent in cosmetic formulations.
A six-amino-acid peptide that acts as an alpha-MSH antagonist, blocking one of the key signals that triggers melanin synthesis in melanocytes.
A synthetic matrikine hexapeptide (Gly-Pro-Gln-Gly-Pro-Gln) that mimics a collagen sequence to stimulate extracellular matrix protein synthesis and support skin regeneration.
A signal peptide marketed to support collagen and firmness.
A synthetic nonapeptide (9-amino-acid sequence) functioning as an alpha-MSH antagonist; it blocks the melanocyte-stimulating hormone receptor to reduce melanin synthesis, used as a skin-brightening active.
A synthetic tripeptide composed of glycine, histidine, and lysine (GHK) that acts as a copper-binding signal peptide, stimulating collagen and glycosaminoglycan synthesis in fibroblasts and supporting skin repair and anti-aging.
A synthetic lysine-serine-threonine oligopeptide that functions as a skin conditioning and signal peptide, activating the skin's endogenous repair mechanisms to support anti-aging activity.
A synthetic tetrapeptide (four amino acids) that acts as a signal peptide in cosmetics, stimulating skin's natural repair processes to improve firmness, elasticity, and reduce visible aging.
A synthetic hexapeptide that mimics the activity of EGF (epidermal growth factor). Stimulates cell proliferation and collagen synthesis, contributing to skin firming and anti-aging benefits. Used in Lululun's Hydra EX mask.
A synthetic oligopeptide that targets tyrosinase — the key enzyme in melanin production — making it a precision brightening active suited for dark spots and uneven tone.
A synthetic signal peptide composed of palmitic acid, alanine, and histidine that provides antioxidant protection, inhibits glycation, and supports skin barrier function with a well-tolerated safety profile.
A signal peptide used to support firmness and a smoother, conditioned skin surface.
