Vitamin C and copper complex: keep them apart

Keep them apart

Apply vitamin C in the morning and copper peptides at night, because mixing them makes both ingredients less effective. Copper reacts with vitamin C and causes it to break down before it can brighten the skin. You can easily fix this by using them at different times of the day.
