How to Use Copper Peptides in Your Skincare Routine
Copper peptides are one of the most potent and science-backed active ingredients in modern skincare. Known for their ability to support collagen production, skin repair, and elasticity, they work best when applied correctly within a skincare routine. This guide walks you through the ideal application steps, what not to layer with copper peptides, how often to use them, and tips for radiant, firmer skin.
What Are Copper Peptides?
Copper peptides are small amino acid fragments bound to copper ions — most notably Glycyl-L-Histidyl-L-Lysine Copper (GHK-Cu). These molecules have been shown to support collagen formation, skin renewal, and barrier health, making them a standout in advanced routines.
Benefits of Copper Peptides
- Stimulate collagen and elastin production for firmer, more resilient skin.
- Support skin repair and regeneration over time.
- Provide antioxidant protection and defense against environmental stressors.
- Improve skin barrier health and hydration when used in synergy with other actives.
Step-by-Step: How to Apply Copper Peptides
To maximize absorption and performance, follow this trusted order:
- Cleanse: Remove impurities with a gentle, non-stripping cleanser.
- Toner (optional): Apply a mild, hydrating toner — avoid strong acids when using peptides.
- Copper peptide serum: Apply your copper peptide product on clean, slightly damp skin.
- Hydrators / serums: Layer hydrating serums like hyaluronic acid or niacinamide next.
- Moisturizer: Seal everything in with a nourishing cream.
- SPF (AM only): Protect your skin with broad-spectrum sunscreen every morning.
What Not to Layer With Copper Peptides
Certain active ingredients can interfere with peptide stability or cause irritation when used at the same time as copper peptides. The most common ones to avoid layering directly include:
- Strong acids: AHAs and BHAs may affect peptide performance.
- Vitamin C (ascorbic acid): Can alter skin pH and reduce peptide effectiveness when layered simultaneously.
- Retinoids / retinol: May increase irritation and reduce peptide effectiveness when layered directly.
If you use vitamin C, acids, or retinoids, consider applying them at different times — for example, vitamin C in the morning and copper peptides in the evening — to avoid potential conflicts.
How Often Should I Use Copper Peptides?
Copper peptides are generally well-tolerated and can be used daily — once or twice depending on your skin sensitivity and routine. If you’re new to active ingredients, start with a few times per week and gradually increase frequency as your skin adjusts.
Do You Moisturize After Copper Peptides?
Yes — after applying a copper peptide serum, follow with a moisturizer to lock in hydration and support barrier health. Moisturizing helps the active peptides work more comfortably and effectively.

What should you not layer with copper peptides?
Avoid strong exfoliating acids (AHAs/BHAs), vitamin C (ascorbic acid), and retinoids when using copper peptides simultaneously to prevent irritation or reduced effectiveness.
How often should I use copper peptides on my face?
Copper peptides can be used daily — once or twice — depending on your skin’s tolerance. Start gradually if you’re new to actives.
Do you moisturize after copper peptides?
Yes — after applying a copper peptide serum, follow with a moisturizer to lock in hydration and support your skin barrier.
