Different categories

Tretinoin is a prescription retinoid, so it's used under the guidance of a healthcare provider. Copper peptides are cosmetic ingredients you can buy over the counter. They're not substitutes for each other; they do different jobs.

A simple way to combine them

Always check with your prescriber before adding new actives to a prescription routine.

  • Morning: cleanse, DOSE, moisturiser, SPF.
  • Evening: cleanse, tretinoin as prescribed, moisturiser.
  • On tretinoin 'off' nights, use DOSE in the evening too.
