Capillary laser (Diolite laser)

Capillary ModelOur office utilizes the Diolite 532 laser for treatment of vascular and pigmented lesions. This laser allows for non-traumatic treatment of facial capillaries, age spots, moles or freckles that may be very noticeable. The mild and precise treatment characteristics of this laser provide consistent, targeted results without the need for anesthesia.

The lesions that are best treated by this procedure are: 1) Vascular lesions caused by abnormally large or numerous blood vessels located directly under the surface of the skin causing a reddened appearance. Spider veins (telangiectasia) are the most common vascular lesions; 2) Pigmented lesions are dark areas occurring when an abundance of melanocytes are found in the skin. These cells when overstimulated produce melanin, the culprit causing the formation of freckles, brown spots and moles.

The laser works by generating an intense beam of light. This beam brings energy to a specific site, through a small handpiece connected to the laser. The laser light is absorbed by oxyhemoglobin (bright red blood cells carrying oxygen) and melanin/pigment (black or brown pigment found in the skin). The light causes decomposition or destruction by heat of the unwanted cells while leaving the healthy cells intact.

Dr. Hand performs the Diolite laser treatment at our accredited outpatient surgical facility as an office procedure. Treatment times and intensity will vary dependent on the characteristics of the lesions and size of the areas being treated. Most treatments last less than 30 minutes. A film of cool gel will be applied to the affected area. A pencil thin hand piece will be used to direct the beam of laser light to the lesion(s). No other topical anesthesia is necessary. Most patients report discomfort similar to being "snapped with a rubber band". The patient may experience a slight redness that disappears after 2 to 4 hours and occasionally minor swelling that resolves quickly. Rarely does bruising occur and normal activities may be resumed immediately.

The final results of the treatment by the Diolite laser are apparent within 10 to 14 days for vascular lesions and 2 to 3 weeks for pigmented lesions. Although lesions will often be corrected, new areas of capillary formation or darkness usually occur for most patients because of further aging changes. Touchup treatments may be performed at 6 week or longer intervals to correct new lesions.
