Copper peptide and squalene: work well together

Work well together

Use them together in the same routine, applying the squalene after the copper peptide. The squalene helps the copper peptide sink in better while keeping the skin barrier strong and moisturized. You can space them out by a few minutes or switch to a gentler formula if your skin feels sensitive.
