Vitamin C and collagen peptide: keep them apart

Keep them apart

Apply vitamin C in the morning and collagen peptides at night, because combining them directly causes the vitamin C to break down and become less effective. Vitamin C can oxidize when it mixes with copper and peptides, which lowers the results you see on your skin. To fix this, simply use them at different times of the day or wait longer between applications.
