Vitamin C and copper

Vitamin C and copper: keep them apart

Keep them apart

Apply vitamin C in the morning and copper peptides at night, because combining them directly makes both ingredients less effective on skin. Copper can break down vitamin C and make it less potent, meaning a shopper might not get the full glow and anti-aging benefits. The shopper can easily fix this by using one in the morning and the other at night, or by waiting longer between applying them.
