    Dose it like the
    clinical.

    Peptide skincare lives or dies on dose, pairing, and packaging compatibility. We formulate at clinically meaningful percentages, stability-test in your exact pump or jar, and pair peptides with the cofactors that make them actually perform on skin.

    Clinically Dosed Peptides

    Copper peptides (GHK-Cu), Matrixyl 3000, Argireline, hexapeptide-9, and growth-factor stacks at efficacy thresholds.

    Stability-Safe Bases

    pH-buffered, low-water, and airless-compatible bases that preserve peptide activity over a 24-month shelf life.

    Sensitive-Skin Sensorial

    Slip, cushion, and finish tuned for post-procedure and clinical positioning β€” never sticky, never greasy.

    Serums, Eye & Treatment Creams

    Airless pumps, frosted droppers, and metal eye tubes β€” the formats that protect peptide activity and signal clinical positioning on shelf.

    Peptide skincare that earns the re-order.

    The Topical Peptide Library

    Every cosmetic peptide we formulate with.

    Peptides are now the #1 fastest-growing active in prestige skincare. From GHK-Cu to Matrixyl, Argireline to growth-factor systems β€” here's the full library we build with, and where each one earns its place on the INCI.

    GHK-Cu (Copper Peptide)

    Copper Tripeptide-1

    Regeneration

    The legendary blue copper peptide. Signals fibroblasts to remodel collagen, elastin, and glycosaminoglycans β€” the closest topical analog to a true post-procedure repair peptide. Anchors longevity, scalp, and post-laser SKUs.

    Matrixyl 3000

    Palmitoyl Tripeptide-1 + Tetrapeptide-7

    Anti-Aging

    The peptide duo that built modern anti-aging skincare. Signals collagen synthesis while quieting inflammatory glycation. The strongest 'wrinkle' peptide claim in mainstream prestige.

    Matrixyl synthe'6

    Palmitoyl Tripeptide-38

    Anti-Aging

    Newer-generation Matrixyl stimulating six skin-matrix components including collagen I, III, IV, fibronectin, and hyaluronic acid. The premium upgrade over classic Matrixyl 3000.

    Argireline

    Acetyl Hexapeptide-8

    Expression Lines

    The 'topical botulinum' peptide. Softens the appearance of expression lines by interrupting muscle-contraction signaling at the synapse. The defining peptide for forehead, crow's-feet, and under-eye serums.

    SNAP-8

    Acetyl Octapeptide-3

    Expression Lines

    Extension of the Argireline mechanism with longer peptide chain β€” often paired with Argireline for stacked expression-line claims. Standard inclusion in injectable-alternative serums.

    Syn-Ake

    Dipeptide Diaminobutyroyl Benzylamide Diacetate

    Expression Lines

    Snake-venom-mimicking peptide that relaxes facial muscles via the nicotinic acetylcholine receptor. The 'third pillar' of the modern injectable-alternative trio with Argireline and SNAP-8.

    Syn-Coll

    Palmitoyl Tripeptide-5

    Firming

    Mimics thrombospondin-1 to activate TGF-Ξ² and drive collagen synthesis. The peptide of choice when a brand wants a single firming hero rather than a Matrixyl-style cocktail.

    Leuphasyl

    Pentapeptide-18

    Expression Lines

    Enkephalin-mimicking peptide that reduces muscle-contraction frequency. Stacks cleanly with Argireline for a multi-pathway expression-line claim.

    Vialox

    Pentapeptide-3

    Expression Lines

    Curare-inspired peptide that blocks post-synaptic acetylcholine receptors for rapid 'smoothing' claims. Useful for instant-effect serums and pre-event spot treatments.

    Decorinyl

    Tripeptide-10 Citrulline

    Skin Architecture

    Regulates collagen fibrillogenesis to organize collagen bundles for smoother, more uniform skin texture. A premium addition to anti-aging and post-procedure SKUs.

    Biotinoyl Tripeptide-1

    Procapil family

    Hair & Scalp

    The flagship peptide in modern hair-density and scalp-health serums. Signals follicle anchoring and improves microcirculation β€” the move when launching a peptide-led hair line.

    Hexapeptide-11

    Yeast-derived

    Longevity

    Studied to reduce senescent-cell markers β€” the 'cellular longevity' peptide. Increasingly used in next-gen prestige and longevity-positioned skincare hero serums.

    Tripeptide-1 / Tetrapeptide-3

    Signal peptides

    Anti-Aging Base

    Workhorse signal peptides used to drive collagen and elastin synthesis claims in everyday SKUs at accessible cost. The base layer beneath premium peptide systems.

    Growth Factor Systems

    EGF Β· FGF Β· TGF analogs

    Regeneration

    Bio-identical growth factor analogs for post-procedure repair, scarring, and barrier restoration. The premium tier for medspa, telehealth derm, and longevity skincare.

    The Peptide Toolbox

    The actives, the bases, and the proof β€” handled.

    Clinically meaningful percentages, stability-tested in your final pump or jar, paired with cofactors that make peptides actually perform on skin.
