- Question: Hi there, I am about to incorporate a serum into my routine that contains copper peptides. I had read somewhere that you shouldn’t use copper peptides with AHAs or BHAs. I was curious if there’s any truth to this? In addition, I do use a PHA serum a few times a week, and I was wondering if I could still layer the peptide serum over it, or if I need to alternate days in which I use each serum? Thanks!
Thank you for contacting us, I would recommend that you alternate the usage of those products either nightly or use one in the morning and one in the evening. It could cause sensitivity and irritation when layering actives with peptides and it’s not recommended.
