The rising ingredient is making its way back into our routines, one peptide-packed product at a time.
I’ll admit it: I had completely forgotten about copper peptides.
Not forgotten forgotten, but in the way that happens when you’re constantly testing the next buzzy skincare ingredient. Retinal! PDRN! Exosomes! Peptides! Suddenly, the ingredient you were obsessed with six months ago is sitting somewhere in the back of your bathroom cabinet.
Then I rediscovered copper peptides at Dr.Reju-All’s recent pop-up at The Grove in Los Angeles.
The K-pharmacy brand built the experience around personalized skin analysis, and after getting my skin assessed, I was guided toward the brand’s Advanced PDRN Copper Peptide Serum. The formula combines 1% multi-peptides and copper peptides with 1,200 ppm PDRN and is designed around a firmer-looking, more conditioned complexion.
And suddenly I was reminded: wait, why aren’t we talking about copper peptides more?
So, What Exactly Are Copper Peptides?
Copper peptides are a skincare ingredient known for supporting the skin’s natural repair processes and helping promote the look of firmer, smoother, more resilient skin. They’re often used to support collagen and elastin, improve the appearance of fine lines and texture, and help maintain a healthy-looking skin barrier. As a peptide-based ingredient, they’re also an appealing option for those looking to add targeted anti-aging benefits without relying solely on more intensive actives.
The appeal is pretty easy to understand.
So I went down the rabbit hole and found a few copper peptide formulas worth knowing about.
Dr.Reju-All Advanced PDRN Copper Peptide Serum
This is the one that restarted my copper peptide obsession.
The formula combines copper peptides, multiple peptides, PDRN, niacinamide, panthenol, hyaluronic acid, and beta-glucan, making it more of a multitasking formula than a one-ingredient serum. The brand says its copper peptides are housed in tiny blue capsules designed to help protect the ingredient until application.
Best for: Anyone curious about the K-beauty/K-pharmacy approach to copper peptides.
