BOTOX® was designed to treat the wrinkles and deep creases that appear around the eyes, between the eyebrows, and the forehead. By reducing the appearance of these wrinkles, patients tend to look more youthful and refreshed.


Acne alone can be a very distressing, physically unattractive condition. Even worse, acne can leave behind scarring that is much more difficult to treat than the acne itself. Acne scars are scars that remain to blemish the skin even after the active acne has been treated and removed.


Juvéderm® is able to smooth and soften facial lines, wrinkles, and acne scars by plumping up the targeted areas. During treatment, hyaluronic acid will be injected under depressions or crevices on the skin’s surface.
