GHK-Cu SNAP-8 Niacinamide Serum
Stacks three actives in a lightweight serum. GHK-Cu drives collagen synthesis and ECM remodeling. SNAP-8 inhibits SNARE-complex assembly (same target as botulinum toxin) to soften expression lines. Niacinamide reinforces the skin barrier and reduces redness.

What It Is
A compounded prescription serum at 3% GHK-Cu, 1% SNAP-8 (acetyl octapeptide-3), and 3% niacinamide in an aqueous vehicle. SNAP-8 inhibits SNARE complex assembly extracellularly, the same protein complex botulinum toxin disables intracellularly. Effects accumulate over 4 to 12 weeks.
How It Works
Applied to clean face once or twice daily. Penetration is rapid because the vehicle is aqueous and lightweight. Layer Cashmere Cream or another moisturizer on top.
Who It's For
Patients targeting expression lines (forehead, between brows, around eyes) who want a topical alternative or adjunct to injectable Botox. Suitable for all skin types.
Who Should Avoid It
Known allergy to copper or any ingredient. Discontinue if persistent irritation. Patch test before full-face application.
