532nm KTP Laser Treatment for Facial Veins, Facial Telangiectasia

What are Facial Telangiectasias?

Facial Telangiectasias are broken or dilated blood vessels or capillaries that are commonly found on the face, nose, chin, and cheek. Telangiectasias can also be found on the other parts of the body such as the legs, chest, back, arms, legs, and lower extremities. These facial vessels are typically smaller than a millimeter in diameter and are red to bluish in color.  They are superficially located underneath the skin and are considered vascular lesions that are usually benign.  However, there are some underlying autoimmune diseases that are associated with telengiectasias,  so please consult with a board certified dermatologist to further diagnose any underlying conditions.

What causes facial telangiectasias?
There are several factors which contribute to the development of facial vessels. The most common factors for telangiectasias are the following: genetics, prolonged sun and wind exposure, medications that can dilate vessels, pregnancy, excessive alcohol use, trauma to the skin, surgical incisions, and acne.

Historically, the only surgical treatment available to treat vascular lesions such as facial telangiectasia was electrosurgical desication of the vessel.  This is a sharp needle that delivers an electrical surge of energy that burns through the skin and coagulates the vascular structure underneath the skin.  Though this is effective to remove the lesion, it also can scar the skin surrounding the telangiectsia. As a result of this undesirable scarring of the skin, the VersaPulse laser has proven to be the gold standard to safely treat vascular lesions of the face while minimizing damage to any surrounding tissue.

The 532nm laser is designed to treat various types facial vessels and vascular lesions called facial telangectasia.  One of the specific wavelengths of light to target oxyhemoglobin is the 532nm which is a wavelength offered by the 532nm laser.  This 532nm wavelength precisely targets these vessels with heat- energy.  The targeted oxyhemoglobin (red blood cells) inside the visibly broken capillaries absorb the laser’s energy and are heated up, coagulated, or closed down.  This process is called photothermolysis.

As a result of this light-based energy exchange between the laser and capillary, many patients will experience  clearance of the telangiectasias on the face, nose, chin, and forehead within hours of the initial treatment.  In addition, the thermal effect of the VersaPulse laser on the skin causes the body’s immune response to send scavenger cells, macrophages, to the treatment site.  Therefore, over a period of 3 to 6 weeks, these macrophages work to absorb the treated capillaries, reducing the vascular lesions or facial telangiectasia.  Depending on the severity of these broken vessels, a series of 3 to 4 VersaPulse treatments are recommended.
