Lactic acid and collagen peptide: keep them apart

Keep them apart

Use lactic acid in the morning and collagen peptide at night, because the acid is too harsh for the peptide. The acidic product breaks down the peptide and stops it from working properly. You can avoid this by using them at different times of day.
