You may experience some lingering warmth, redness or tightness in the area that was treated. This fades within a few hours. Because so much of the skin is unaffected by the light pulses, there is a quick healing process. Generally, you can have a treatment and return to work or anything else without any recovery time. A series of treatments at regular intervals may be required to achieve the desired result of smoother, tighter skin in the face, arms, abdomen, and other areas.
