What They Are
Growth factors are proteins that “regulate cell growth and cell division in the skin,” says celebrity aesthetician Gina Mari. “We have synthesized growth factors to heal injuries and wounds and stimulate the immune system.” When skin is damaged, the production of growth factors slows and the skin can look weathered.

How They Work
Growth factors are absorbed by cells in the epidermis and dermis, “signaling surrounding tissues and cells to incite wound-healing,” says St. Augustine, FL, facial plastic surgeon Patrick Angelos, MD. Products with growth factors stimulate tissue regeneration and create collagen and elastin.

What You’ll Notice
According to High Point, NC, dermatologist Zoe Draelos, MD, many products with growth factors hydrate because of the carrier vehicle they are packaged in. New York dermatologist Patricia Wexler, MD says growth factors can facilitate pathways for peptides and antioxidants, which drive repair. This is why they are often in skin-care products, too.
