Can You Use Vitamin C With Copper Peptides and Tretinoin?
Yes, but timing matters. You can use vitamin C whenever you like, but it doesn’t play well with copper peptides. If you use both, leave 2 hours between them so your skin’s pH can rebalance.
The products
- Vitamin C Serum: 15% L-ascorbic acid.
- GHK-Cu Copper Peptides Cream: custom-compounded in 2%, 3% or 4% strength.

Sandra, I used it last night all over my face, all over my body after I exfoliated, and then I put my retinoic acid on. Fantastic. You can use your vitamin C whenever you like, but it does not play well with copper peptides. So use it whenever you like, but if you’re going to use it with copper peptides, you must leave 2 hours for the pH of your skin to rebalance.
