Choose copper peptides if…
- Your skin is sensitive, or retinol has irritated you before.
- Your main goal is firmer-looking, bouncier skin.
- You want something you can use twice a day with no adjustment period.
- Your skin barrier feels compromised.
Choose retinol if…
- Texture and breakouts are your biggest concern.
- Your skin tolerates strong actives well.
- You're happy to use it at night only and be strict with SPF.
Using copper peptides and retinol together
You don't have to choose. A popular approach is DOSE morning and night, and retinol a few nights a week after DOSE has absorbed. If your skin gets irritated, alternate nights: DOSE one night, retinol the next.
Many people find that copper peptides make a retinol routine more comfortable, because they help skin look and feel calmer.
FAQ
Is copper peptide better than retinol?

Yes. Apply the copper peptide serum first, let it absorb, then apply retinol. If you get irritated, alternate nights instead.
Can copper peptides replace retinol?
For people who can't tolerate retinol, a copper peptide serum is a common alternative for supporting the look of firmer, smoother skin.
