When I first integrated The Ordinary into my routine, I was fascinated by the "blue serum"—officially known as the Multi-Peptide + Copper Peptides 1%. It promised a comprehensive approach to skin health, utilizing advanced peptide technologies to target multiple signs of aging. However, the world of ingredient compatibility can be complex. If you are wondering, "Does copper peptides conflict with any ingredients?" you are not alone. Through my own experiences and research, I have learned how to manage these conflicts to ensure I get the most out of my skincare investment.

The Core Conflicts: What to Avoid
The most critical rule I follow is to avoid peptides with Resveratrol & Ferulic Acid. While these are excellent antioxidants, they can potentially interact with the copper molecules, rendering them less effective.
Furthermore, Copper Peptides are the ones that cannot be used with other actives like direct acids (AHA, BHA) or strong Vitamin C derivatives.

Integrating into Your Routine
To help you avoid common mistakes, here is how I structure my day:
* The "Buffet" Strategy: I reserve my Buffet (the original formula) for times when I want to layer with other potent serums.
* The Blue Serum Rule: When using the Copper Peptides version, I keep my routine simple. I cleanse, apply the blue serum, and finish with a simple moisturizer.
* Active Management: Since Copper peptides are known for their ability to combat the visible signs of aging, I don't want to waste them. I never apply them at the same time as my retinol or exfoliating acids.
