CUSTOM - GHKcu + SNAP8

A versatile multi-peptide serum that brings the best of both worlds into a single bottle.

$65

1 oz / 30 ml

GHK-Cu (3%) supports the appearance of firmer, more resilient skin — the foundational copper peptide behind Renew. SNAP-8 (3%) targets the look of expression lines around the forehead, eyes, and mouth — the peptide that defines Freezer. Together, in a clean hyaluronic acid base, they deliver structural support and expression-line work in one step. The do-it-all formula for those who want one serum, used morning and night, across the entire face.

II. The Actives

What’s inside, and why.

GHK-Cu (Copper Tripeptide-1), 3%
—
Naturally occurring copper-bound peptide that supports the appearance of firmer, more resilient skin. The foundational peptide behind Renew.
SNAP-8 (Acetyl Octapeptide-3), 3%
—
An eight-amino-acid peptide developed to support the appearance of smoother, more relaxed skin in expression-prone areas. The targeted peptide behind Freezer.
Palmitoyl Tripeptide-1
—
A fatty-acid-modified peptide that carries actives through the skin's lipid barrier for layered delivery.
Sodium Hyaluronate
—
A low-molecular-weight humectant that carries the actives and supports moisture retention in the upper layers of the skin.

Use morning and night. Apply two to three drops to clean, toned skin across the full face and neck, pressing gently into the skin. In the morning, follow with sunscreen. In the evening, finish with moisturizer. Custom is designed as a do-it-all serum — one bottle, the full face, twice daily. GHK-Cu for foundational support, SNAP-8 for expression-prone areas, in a single layered step. Allow four to six weeks of consistent use for visible results.
