9 Best Growth Factor Serums for 2024 (Tested and Reviewed)
If your goal is smoother, tighter, firmer skin, then yes, growth factors really do work. "Growth factors stimulate fibroblasts, the cells responsible for collagen production, leading to improved skin texture and firmness and a reduction in fine lines and wrinkles," says Dr. Rogers. Growth factors are also able to improve your skin's wound healing process and help repair damaged skin.
Some growth factors can even help calm the skin by turning off inflammation pathways, improving skin barrier function, and decreasing redness, adds Dr. Rogers.
Dr. Chang says it typically takes six to eight weeks of consistent use to see any of the above changes in your skin, so remember that patience is key when adding a growth factor serum to your routine.
