Treated vascular lesions blanch briefly when exposed to the yellow light. A single session rarely exceeds 40 minutes, depending on the extent of the skin problem. The treated skin appears quite red for a few hours. The green light causes the surface of pigmented lesions to go grey and then form a dark scab. After a couple of weeks the skin peels off leaving a paler lesion.
Combined light acts like electrocautery and destroys lesions that can be scraped off easily.
For best results, most patients require two to four treatments , usually at intervals of at least six weeks. If you have any concerns with your skin or its treatment, see a dermatologist for advice.
