Botox works by relaxing muscle contraction, after which the overlying skin becomes smoother and less wrinkled. The effect of frowns and smile lines are dramatically reduced, as the movement of the muscle is restricted. The treatment lasts four months or more, and will leave you with a look and feel that you will love. While “dynamic” lines can be treated with Botox alone, when the wrinkle lines are visible even when the muscles are at rest, these “static” lines are best treated using a combination of Botox and dermal fillers. Dermal filler is a non-animal, natural substance that exists as a structural element in your skin. It works by pushing up under the wrinkles or scar, thereby restoring a smoother, flatter skin contour. The dermal filler is naturally integrated into the skin and will in time re-absorb. Typical wrinkle improvement is between 50% and 90%, depending on the location and severity. Dermal fillers can be used to soften smile lines, crow’s feet (corner of the eyes), frown lines (between the brows), worry lines (across forehead), marionette lines (corner of mouth), smoker’s lines, deep neck lines, wrinkles, acne scars, and depressed scars. Dermal fillers that Dr. Kang usually recommends are either Juvederm or Radiesse. There is almost no downtime with usually only temporary swelling and rarely bruising or transient redness to the injected site, to a point where most patients are usually able to go back to work on the same day or following day.
