GHK-Cu

The cosmetic-peptide canonical

Copper Tripeptide-1

INCI Copper Tripeptide-1·Use level 0.5–2 %·pH 5.5–7.0

Isolated from human plasma in 1973 and the textbook example of an endogenous copper-peptide complex, GHK-Cu is widely used in cosmetic formulation research. Ask sales for the matching batch COA and scope any copper-content or carrier-stability evidence required for the project.

AHK-Cu

The hair-follicle copper variant

Copper Tripeptide-3

INCI Copper Tripeptide-3·Use level 0.1–1.0 %·pH 5.0–6.5

The Ala-His-Lys structural analog of GHK-Cu, with the N-terminal glycine swapped for alanine. The substitution shifts the molecule's tissue-distribution preference toward the scalp and follicle, which is why AHK-Cu lives in hair-regrowth serums rather than dermal-repair creams. Mutually compatible with GHK-Cu in combined scalp-plus-skin programmes.

SNAP-8

The expression-line wrinkle reducer

Acetyl Octapeptide-3

INCI Acetyl Octapeptide-3·Use level 3–10 %·pH 5.5–7.0

An 8-amino-acid acetylated peptide mimetic of the SNAP-25 N-terminus, designed as an extension of the classic Argireline molecule. SNAP-8 lives in topical formulations targeting forehead, glabellar, and periocular expression lines. Typical use levels settle at 5–8 % of the finished product; we stock it kilo-scale for OEM finished-product runs.

View Active

Matrixyl

The collagen-mimetic anti-aging peptide

Palmitoyl Pentapeptide-4

INCI Palmitoyl Pentapeptide-4·Use level 3–8 %·pH 5.0–7.0

A palmitic-acid-conjugated pentapeptide based on the KTTKS fragment of human procollagen type I — the palmitoyl group is a delivery vehicle that lets the peptide cross the stratum corneum and reach dermal fibroblasts. Mechanistically complementary with GHK-Cu and SNAP-8, the three peptides stack cleanly in a multi-active anti-aging serum.

The supporting diluent is clearly separated from the cosmetic-active specifications; every featured peptide retains its full INCI documentation and formulation-stability data.
