There are many types of peptides, each with a unique efficacy and function; for instance, some peptides are known for reducing inflammation, while others are superb at barrier support. You can read all about the different types here, but just know that copper peptides are A+ for collagen production.
See, “The skin does naturally contain copper,” says board-certified dermatologist Dhaval Bhanusali, M.D., FAAD, founder of Hudson Dermatology and Laser Surgery, and it’s essential for fibroblast proliferation, upregulating collagen and elastin fiber components, and wound healing. By applying copper peptides topically on the skin, he says you can stimulate collagen production and slow down wrinkle formation.
“They have specifically been shown2 to stimulate fibroblast production in vitro and are used to increase collagen and elastin production, which helps plump the skin to reduce the appearance of fine lines,” Bhanusali continues. “It’s also thought to have anti-inflammatory properties, which is great for calming the skin.”
