As we age, gravity begins to take its toll. The “parentheses” around our mouths may slowly become more prominent, and some people develop deep lines on the sides of the chin, known as marionette lines. Gravity causes the fat pads below the skin level to migrate toward the lower face. This causes deep lines to form around the mouth and on the sides of the chin. Many women and some men become bothered by these signs of aging, and elect to do something about them. Although there are many options for treating facial lines, fillers are the most efficacious for these problem areas.
