Glycolic acid and collagen peptide: keep them apart

Keep them apart

Use them at different times of day, applying glycolic acid in the morning and collagen peptide at night, because the acid is too harsh. The strong acid breaks down the peptide and stops it from working properly. You can easily fix this by using them in separate routines or waiting longer between steps.
