Serums and creams are a wonderful way to begin to keep lines and wrinkles at bay. However, over time, wrinkles can become more and more prominent, especially those that are caused by repeated muscle contractions. These expression lines often show up as forehead lines that run horizontally across the forehead and worry lines or the “elevens” that show up between the eyebrows. Other lines that are caused by repeated muscular movements are called laugh lines, lip lines, and marionette lines. Due to the fact that these lines are caused by repetitive muscular movements, it is harder to combat them with just serums. For these tough lines, Botox is the treatment of choice!
