Tretinoin and hexapeptide: keep them apart

Keep them apart

Use them at different times of day by applying your peptide product in the morning and tretinoin at night to prevent skin irritation. Using both active ingredients at the same time can overwhelm your skin and cause redness or irritation. You can easily fix this by giving your skin more time between applications or using a gentler formula.
