Salicylic acid and collagen peptide: keep them apart

Keep them apart

Use them at different times of day by applying salicylic acid first and collagen peptide later, because mixing them makes the peptide useless. The strong acid in salicylic acid breaks down the peptide structure so the skin does not get any of the firming benefits. The shopper can fix this by using the salicylic acid in the morning and the peptide at night.
