Frequently Asked Questions

What is eye cream dark circles peptides caffeine?

The better-studied actives - Matrixyl-type signal peptides and GHK-Cu - show modest improvements in wrinkle depth and firmness in small controlled trials over 4-12 weeks. Effects are real but smaller than retinoids or vitamin C.

What does copper peptide do for skin?

GHK-Cu carries copper into skin where it supports enzymatic repair and crosslinking pathways; published work shows improved firmness, elasticity and wound-repair markers. It is the cosmetic peptide with the deepest literature.

Can I mix eye cream dark circles peptides caffeine with retinol or vitamin C?

Peptides generally layer well with other actives; apply strong acids or vitamin C at a different step to avoid peptide stability issues at very low pH. Consistency over months matters more than perfect layering order.
