(Excerpt) Every so often there’s a new skin-care ingredient that seems to seep its way into our vocabulary. (Remember Bakuchiol? Squalane? Snail mucin?) Today that ingredient is copper peptides—and beauty influencers love to tout its benefits.
“If you haven’t tried this skin-care product, you will after watching this video,” says baby-faced TikToker Abbey Yung. She’s talking about a product by Canadian beauty brand The Ordinary featuring copper peptides that she says “took [her] skin to the next level.” What does the ingredient do exactly? According to influencers like Yung, it stimulates collagen and elastin production, to help you recapture a youthful glow.
Today, the copper peptide hashtag on TikTok has raked in over 31 million views and a slew of products spotlighting the ingredient are popping up on store shelves—so what do the pros think?
What are copper peptides?
“They’re found in the skin as well as being exogenous,” says dermatologist at DLK on Avenue Dr. Lisa Kellett, which means they occur naturally but can also be manufactured synthetically and added to skin care products. “They play a role as an antioxidant, but there’s not a lot of evidence-based medicine that supports their use,” she says.
Does that mean we don’t know for sure what their benefits are?
While there’s evidence of the effectiveness of antioxidants like vitamin C, says Kellett, copper peptides are lacking the research needed to make factual claims on its effectiveness. But, she says, “there’s been some data to suggest they’re important in collagen remodelling and regeneration.”
What types of skin-care products are they typically found in?
They’re most commonly in serums, says Kellett, but can also be found in moisturizers.
