Vitamin C and peptide-rich plasma: keep them apart

Keep them apart

Apply vitamin C in the morning and peptide serum at night, because mixing them together makes the vitamin C less effective. Vitamin C and copper peptides clash on your skin, which cancels out their anti-aging benefits and can cause irritation. To fix this, simply use them in separate routines or wait longer between applications.
