We sell both a Copper Peptides Serum and a Matrixyl 3000 serum, so we get this from people building a fuller routine: do these two compete, or do they work together? Short version — they're a great pair, and using both is one of the strongest ways to support firmer, smoother-looking skin.
Why these two peptides work so well together
Matrixyl 3000 and copper peptides (GHK-Cu) both support the look of firmer, smoother skin — in different ways, so they complement each other instead of competing. Matrixyl 3000 is a dual-peptide complex for firmness and fine lines; GHK-Cu, in Asterwood's Copper Peptides Serum, is one of skincare's most-researched single peptides for firmness and texture. Different actives, one shared goal, no known conflict.
How to build a routine with both
- Cleanse.
- Apply Copper Peptides Serum first — it's thinner and faster-absorbing. Wait about a minute.
- Apply Matrixyl 3000 + Argireline Serum.
- Follow with moisturizer, then SPF in the morning.
What to keep in mind
Keep either serum in its own step, apart from strong AHAs/BHAs or high-dose Vitamin C (see our Copper Peptides + Retinol compatibility guide). If your skin feels sensitive after adding a second serum, that's usually just two new products at once rather than a peptide conflict — so add one at a time when you're starting both, and you'll settle into the routine quickly.
