Copper and palmitoyl pentapeptide-4

Rated by Lovi · Unbiased, science-based skincare AI trained on real user outcomes · How the Fit score works

Keep them apart

Use them on alternate nights, applying copper peptides on even days and palmitoyl pentapeptide-4 on odd days, because they cancel each other out. Mixing these two powerful ingredients causes them to break down and stop working, giving you less results from your skincare routine. You can fix this by waiting a few minutes between steps or using one in the morning and the other at night.
