The Copper-Peptide Anti-Ageing Mask: Everything You Need to Know
The short answer
A copper-peptide anti-ageing mask delivers a concentrated dose of peptides to firm and smooth the look of skin. An overnight treatment like the PRIME Sleep Tight Mask renews and firms skin while you sleep.
Masks are usually about a quick hit of hydration or a deep clean — but a copper-peptide anti-ageing mask is different. It delivers a concentrated dose of firming actives in one relaxing step, making it an intensive boost to a copper-peptide routine.
What a copper-peptide mask does
By holding a high concentration of copper peptides against the skin, an anti-ageing mask supports collagen and firmness while it works — helping smooth and firm the look of skin. It's a treatment, not just a pamper.
How and when to use it
Use it as a weekly boost or overnight treatment, layered over hyaluronic acid. It complements — rather than replaces — your daily copper-peptide cream.
