Retinal and palmitoyl pentapeptide-4: keep them apart

Keep them apart

Use them at different times of day by applying retinal at night and palmitoyl pentapeptide-4 in the morning. Using both strong ingredients at the same time can cause extra skin irritation and redness. You can switch to a gentler retinal strength or leave more time between applying them.
