Can you use Vitamin C with Copper Peptides?
Yes, with timing. Use vitamin C and copper peptides at different times of day.
Why
Direct evidence is limited. A commonly cited concern is that low-pH vitamin C may interact with copper complexes, so many experts suggest separating them.
How to use them together
- AM: vitamin C, sunscreen. PM: copper peptides.
Who should be careful
People with very sensitive skin, rosacea or eczema should patch test new products first.
