Retinol and palmitoyl pentapeptide-4: depends on the strength

Depends on the strength

Use them at different times of day, applying the peptide cream in the morning and the retinol at night, because strong retinoids can clash. Retinol speeds up cell turnover while peptides help firm the skin, and they work best when you give your skin a break. You can switch to a gentler retinol strength or wait a little longer between steps if your skin feels irritated.
