Benzoyl peroxide and collagen peptide: keep them apart

Keep them apart

Use them at different times of day, applying collagen peptides in the morning and benzoyl peroxide at night, because heat and harsh chemicals break down peptides. Benzoyl peroxide can cancel out the firming benefits of collagen peptides by breaking down their delicate structures. The shopper can separate application times or switch to a gentler spot treatment to avoid losing results.
