GHK-Cu Copper Peptides Duo
FIRM, HYDRATE & RENEW
Two steps. One powerhouse peptide. The Peptides Edit Bundle pairs our bestselling Copper Peptides Serum with the new Copper Peptides Booster Cream for a complete copper peptide routine — treat, then lock it in.
GHK-Cu (Copper Tripeptide-1) is one of skincare's most-researched peptides, and here it works in two textures: a lightweight serum that visibly firms and smooths the look of skin, and a richer booster cream that seals in moisture and helps skin look calmer, smoother, and more resilient. Every Asterwood formula starts with Hyaluronic Acid — a natural polysaccharide that draws in and holds moisture — so skin stays plump and every active works harder.
Copper Peptides Serum (the treatment step)
A minimalist 6-ingredient serum built around GHK-Cu copper peptides and 1.5% Hyaluronic Acid to visibly firm, smooth, and refine the look of fine lines and uneven texture. The signature blue-green color is the natural sign of active copper peptides in the formula.
Copper Peptides Booster Cream (the lock-in step)
A lightweight peptide cream that builds on the serum with GHK-Cu, Ectoin, Shea Butter, and Hyaluronic Acid to seal in hydration, support the look and feel of the skin's moisture barrier, and help skin look smoother and more even over time.
