Cold Laser Therapy for the Removal of Vascular lesions & Pigmentations

Dr. Barnett can treat Telangiectasis, Cherry Angiomas, Spider Angiomas, Rosacea, Lentigines, Keratoses, Dermatosis Papulosis Nigra, Brown Spots, Freckles as well as facial and leg Spider Veins.

Laser technologies are commonly used in medicine today, but each system is designed for specific purposes. Dr. Barnett’s laser is “surgical” because it uses just a pinpoint of light that traces over the problem veins and pigmentations rather than using a broader application of laser light as most other laser clinics. This allows for more precision, and less potential for unwanted skin interactions with the laser. The sensation is most often described as like a rubber band snap.

The procedure is FDA approved.

How does the laser work?
A intense beam of light produced by the laser is absorbed by the melanin/pigment (dark colors) causing that tissue to die and either be absorbed or gradually exfoliate.

It may take 10-14 days to see the full results for pigmented lesions and two or three weeks for vascular problems.  Redness initially, followed by itchiness are the usually side effects from treatment

What conditions are treated with the laser? Vascular Lesions

Telangiectasia are usually called  “spider veins” and are caused by a dilation of capillaries and arterioles.
Angioma is a benign that arise from the walls of of small vessels. They are usually tiny and red colored.

Rosacea is a red-ish lesions, usually on the face, that looks like a sunburn.
Pigmented Lesions:

Lentigines are flat, brown spots associated with frequent sun exposure, and are often referred to as “liver spots”.

Keratoses are elevated and often pigmented spots often found on the back and hands

Freckles are a brownish spot on the skin common on people with fair skin.
Dermatosis Papulosis Nigra are usually tiny black marks seen primarily on people of Asian or African descent.


Dr. Barnett also performs Non-surgical reduction of skin tags and moles using TCA (a chemical applied which causes the tissue to die an slough off in time). No injections required for this procedure. A numbing agent is offered to reduce a mild to moderate stinging sensation associated with treatment.
