Hydroxypinacolone retinoate and hexapeptide-9: keep them apart

Keep them apart

Use them at different times of day by applying hexapeptide-9 in the morning and hydroxypinacolone retinoate at night, to avoid extra skin irritation. Both ingredients work hard to smooth the skin, and using them together can cause redness and irritation. The shopper can prevent this by using them in separate routines or switching to a gentler formula.
