Peptide Shot Ampoule

A gold-standard humectant that draws water into the skin.

A versatile vitamin B3 derivative with multiple benefits.

A trimer of glycerin used as a humectant and skin-conditioning agent that hydrates and improves the feel of cosmetic formulas.

A nucleoside used at low concentrations to help smooth the look of fine lines; a common K-beauty anti-aging active.

A polysaccharide humectant that hydrates and calms; often compared to hyaluronic acid.

A naturally occurring amino acid that acts as a humectant and supports the skin's own moisture-retention system.

A licorice-root-derived salt that calms inflammation and soothes irritated, reactive skin.

The salt form of hyaluronic acid; penetrates more readily.

Mallotus japonicus leaf extract (EU CosIng REF 82898) is derived from the leaves of akamedoki/akamegashiwa, a deciduous East Asian tree in the Euphorbiaceae family. Its phytochemical profile — ellagitannins (mallotinic acid, mallotusinic acid, corilagin, geraniin) and the dominant flavonoid rutin — delivers EGCG-equivalent antioxidant activity, tyrosinase-inhibiting brightening, and iNOS/NO-suppressing anti-inflammatory properties. Sourced from Jeju Island (Korea); listed in EU CosIng for antioxidant, antimicrobial, and skin-protecting functions.

A complex mixture of proteins, peptides, amino acids, vitamins, and polysaccharides derived from Saccharomyces cerevisiae yeast, used as a skin-conditioning and protecting active.

Helichrysum arenarium (sand everlasting / dwarf everlasting) extract is derived from a flowering Asteraceae plant native to Europe and Central Asia, distinct from H. italicum (immortelle). Its unique phytochemicals — arenariumosides I–IV (species-specific TNF-alpha inhibitors), isosalipurposide (dominant chalcone), and flavones (apigenin, galangin, kaempferol) — deliver potent anti-inflammatory activity comparable to indomethacin in vivo, antioxidant and UV photoprotection, and documented anti-sebum effects (EU CosIng REF 34242, CAS 85665-35-6). A protected species in some European countries; verify sustainably sourced material.

A signaling peptide that supports skin repair 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 branched polysaccharide of α-D-glucose units primarily linked α(1→6), produced by fermentation of Leuconostoc mesenteroides. Distinct from dextrin (a partially hydrolyzed starch). In cosmetics, dextran forms a hydrophilic film on skin surfaces, providing temporary plumping, hydration retention, and a silky skin feel. Used in premium serums and masks for its biopolymer moisturizing and film-forming properties.

Trifluoroacetyl Tripeptide-2 (sequence TFA-Val-Tyr-Val; trade name Progeline™, Lucas Meyer Cosmetics/IFF; CAS 64577-63-5) is an anti-senescence signal peptide that targets progerin — a truncated lamin A splice variant that accumulates in aging fibroblasts and drives cellular senescence. Reducing progerin slows the molecular aging program while simultaneously inhibiting MMP-1/-3/-9 and elastase, upregulating syndecan-1, and activating the Nrf2 antioxidant pathway. Clinical trials at 4 ppm (8 weeks) showed +20% firmness and +20.9% elasticity with measurable reduction in jawline sagging. Used at extremely low concentrations (0.0004–0.002%) in premium anti-aging serums and ampoules.

Glucosylrutin is rutin (a flavonoid glycoside: quercetin-3-rutinoside) with one or more glucose units attached via enzymatic transglucosylation, producing a more water-soluble derivative. The modification preserves the antioxidant and vascular-protective activity of rutin while enabling its use in aqueous cosmetic formulas where native rutin is poorly soluble. Used in K-beauty serums as a gentle antioxidant and anti-redness active.

A biomimetic signal peptide of palmitic acid and lysine-valine that stimulates collagen and elastin synthesis through the TGF-beta pathway, improving firmness and reducing the appearance of wrinkles.

Tetradecylaminobutyroylvalylaminobutyric Urea Trifluoroacetate (Inyline, Lipotec/BASF) is a long-chain lipopeptide derivative that mimics the acetylcholine receptor-blocking activity of waglerin-1, a peptide from the temple pit viper (Tropidolaemus wagleri). By competitively antagonizing the muscular nicotinic acetylcholine receptor (nAChR), it reduces the force of facial muscle contraction and thereby softens dynamic expression wrinkles. Its mechanism complements SNARE-targeting peptides (e.g., Acetyl Hexapeptide-8) and collagen-stimulating signal peptides, making it a frequent component of comprehensive anti-aging peptide ampoules.
