DUA Copper Peptide Serum — 2% GHK-Cu

Cleanse your face and gently pat it dry. Applying serum to clean skin helps it absorb properly and work more effectively. You can use it on slightly damp skin to boost absorption if you prefer.

Dispense 3 to 4 drops into your hands or directly onto your face. Gently press and pat it into the skin rather than rubbing — this helps the copper peptides absorb without wasting product. Use it both morning and night for best results.

Follow with your moisturiser to seal everything in. In the morning, always finish with an SPF, as this is the single most important step for protecting your skin and maintaining results over time.

Consistency is key

Copper peptides work gradually by supporting your skin's natural renewal process. This isn't an overnight fix — most people start noticing firmer, more radiant-looking skin around the 8 to 12 week mark with daily use. Stick with it.

What to avoid

Don't layer copper peptides directly with Vitamin C or strong exfoliating acids, as they can cancel each other out. Use them at opposite times of day — for example, Vitamin C in the morning and copper peptides at night.

FAQ

How long until I see results?

Copper peptides work gradually rather than instantly. They support your skin's natural collagen and repair processes, which take time. With consistent daily use, most people begin to notice firmer, smoother and more radiant-looking skin somewhere between 8 and 12 weeks. The key is using it every day without skipping — think of it as a long-term investment in your skin rather than a quick fix.

Does it feel sticky or greasy?

Not at all. This was one of the biggest issues we wanted to get right. Many copper peptide serums sit heavy or tacky on the skin, but ours is lightweight and water-light, absorbing within seconds. It leaves no residue and layers cleanly under moisturiser, SPF and makeup without any pilling.

Does it have a strong or unpleasant smell?

No. A lot of copper peptide serums have an off, metallic or fishy scent that puts people off using them. Ours is fragrance-free with no unpleasant odour, so it's easy and pleasant to use every day.

What skin type is this suitable for?

All skin types, including sensitive skin. The formula is designed to be gentle enough for daily morning and night use. If you have very reactive skin or any concerns, we always recommend patch testing first and introducing any new product gradually.

Can I use it alongside retinol or Vitamin C?

Yes, but timing matters. Copper peptides and Vitamin C can reduce each other's effectiveness if applied together, so it's best to separate them — many people use Vitamin C in the morning and copper peptides at night. The same goes for strong acids and retinol; alternate them rather than layering all at once.

How should I store it?

Keep it in a cool, dry place away from direct sunlight, which helps preserve the potency of the active ingredients. There's no need to refrigerate it, but avoid leaving it somewhere hot like a sunny windowsill.

Is it cruelty-free?

Yes, always. Our products are never tested on animals.
