When asking "can copper peptides cause skin irritation," the answer is that it depends on your routine. I have found that:
1. Avoid Layering Conflicts: Copper is highly reactive. I personally avoid using strong acids or high-strength Vitamin C at the same time as my copper serum to prevent oxidation and potential sensitivity.
2. Start Slow: Copper peptides are non-comedogenic, but as with any active, your skin needs time to adjust.
3. Consistency is Key: They help in reducing hyperpigmentation, but this is a cumulative process. You won't see results overnight; it requires long-term, consistent application.
