Dr. Green opines, “If the fine lines and wrinkles are caused by dehydration, drinking plenty of water and applying a hydrating moisturizer can soften their appearance. Using retinol or Retin-A may also help diminish fine lines and wrinkles as they stimulate collagen synthesis and increase skin cell turnover. However, dynamic wrinkles caused by repetitive muscle movement (for example, furrowing and raising your eyebrows) likely will not go away on their own as the muscle movements break down collagen in the creases.”
