Frown lines occur as furrows between your eyes. As you age and the skin loses elasticity, formerly fine frown lines can become deep and prominent wrinkles. Some people feel their frown lines give them a sad or angry appearance. At Dr. Umed Cosmetics, you can smooth wrinkles and lines on the forehead with anti-wrinkle injections. For an enhanced correction, you can also use dermal fillers to completely soften those creases.
