The Cutera LimeLight is a non-invasive light treatment which can be used anywhere on the body to remove unwanted pigment or brown spots. The emitted light heats up the pigment cells, which damages them. Spots initially darken. Over one to three weeks the pigment flakes off and fades. The number of treatments required depends on the depth and colour of the pigmented area. One to three treatments spaced three to four weeks apart are usually sufficient to achieve desired results.
Patients experience a mild pinching or stinging sensation each time the light emits its pulse. Treatment times vary depending on the area treated, ranging from 5 minutes for individual spots to 45 minutes for an entire face. Skin may appear slightly red and swollen, lasting a few hours and possibly a few days. Clients can return to normal activities right away. The use of sunscreen is necessary on any treated areas that are exposed to sun.
