Pharos Excimer Laser for Psoriasis Treatment

At OC Skin Institute, our team of professionals and board-certified dermatologist Dr. Tony Nakhla routinely use the Pharos Excimer Laser to treat psoriasis. During this therapy, a laser penetrates the skin to break up the cells that form plaque. The laser transmits an ultraviolet light to treat psoriasis lesions. Since the Pharos Excimer Laser device is small, we perform this treatment in our office. Those who undergo this laser treatment often have long periods of remission between outbreaks.

How is Pharos Excimer Laser Therapy Beneficial?

Each laser therapy session only takes a few minutes to complete. Dr. Nakhla targets specific regions of the skin, which means that patients do not need to worry about the laser affecting or spreading to other areas of the skin. Pharos Excimer Laser therapy can treat psoriasis spots faster than artificial UV light. The laser is even effective on areas that are difficult to treat. For example, it is commonly used to treat psoriasis on the knees, elbows and scalp.

Are There Any Side Effects?

The side effects are usually minimal. Those who undergo this form of laser therapy may experience redness, blistering and itching. Some patients may also experience a burning sensation or an increase in pigmentation.

What are the Risks?

Researchers have yet to identify any medical risks. With that said, doctors do not recommend this treatment for those who have lupus or a history of skin cancer. Those who are pregnant should wait until their baby is born before undergoing Pharos Excimer Laser therapy. Some patients are highly sensitive to light. In these cases, the dermatologist can use a lower dose to treat the patient.

The Treatment Process

Treatment time varies based on each patient’s skin type and the severity of skin lesions. Some patients may need to undergo multiple treatment sessions. According to the American Academy of Dermatology, most patients need two to three treatments per week. Doctors prefer waiting at least 48 hours between each therapy session. Most patients need 10 to 12 treatment sessions to clear their psoriasis. Some patients notice results after a single session.
