Laser Treatment for Psoriasis

Lasers Are An Effective Option For Treating Psoriasis

Many people suffer from a skin disease that causes swelling, pain, redness as well as scaling. This is known as psoriasis. It’s normal for a person’s skin cells to go deep into their skin and then slowly come to the surface. Under normal circumstances, this process takes approximately 30 days. When a person has Psoriasis, this process occurs within a few days. This results in too many cells being on the surface of the skin at the same time. These patches of skin are sore and itch. Psoriasis can show up on a person’s knees, elbows as well as legs, scalp, lower back and more. There are many different options for treating this condition including medicated creams, oral medication and more. One of the most effective is laser treatment.

Laser Treatment for Psoriasis

Laser Treatment

Treating psoriasis with lasers involves sending beams of light to specific areas on a person’s skin. This type of treatment provides focused doses of light to manage mild to moderate psoriasis. It is able to be done without causing any damage to the healthy skin around the affected areas. Laser treatment is even more effective than traditional light therapy. It can reach deeper and produce more positive results in fewer sessions. Some people may be treated with a handheld laser wand. This is an effective way to treat psoriasis in areas that are difficult to reach. This includes the soles of the feet, scalp, elbows and more. There are currently two different types of lasers commonly used during psoriasis treatment. They are excimer laser as well as pulsed dye laser (PDL).

Pulsed Dye Laser (PDL)

This treatment utilizes an organic dye combined with a solvent that is delivered using a laser. These dyes could be coumarin, tetracene, rhodamine and more. The solvents could be ethanol, methanol as well as cyclodextrin and more. The laser is able to place the liquid into the affected areas. The light will excite the dye molecules and cause them to cover the affected area. The laser is a way for the dye to be transmitted, reflected as well as absorbed. The laser light is absorbed only by the targeted area.

PDL Procedure

PDL treatments involve putting a hand piece on the surface of psoriasis. It is then activated. It is common for patients to feel each pulse of light as if it were a rubber band being snapped against their skin. An anesthetic may be applied when the procedure is complete. When the PDL treatment is over, individuals will be recommended to avoid wearing loose clothing. It is good not to have clothing rub against the treated area. Things such as contact sports, hot baths as well as saunas should be avoided.

Excimer Laser

This type of laser is able to deliver a high intense dose of ultraviolet B (UVB) light to a very focuses area. This laser light will not touch any of the surrounding skin. This decreases the chances of radiation exposure. This procedure is also able to be used with mild as well as moderate cases of psoriasis. Desired results can be obtained with as little as two treatments lasting up to 30 minutes for a few weeks. A physician will determine the amount of ultraviolet light required based on the thickness of a person’s psoriasis plaque.


With this type of treatment, people could develop purple-colored spots on their skin. Blistering could occur. It’s even possible for a person to temporarily experience stinging, itching, redness as well as a burning sensation.


Many studies have shown that individuals with psoriasis experience significant improvements from being treated with lasers. The results can last up to twelve months. Noticeable benefits may be experienced after only eight sessions.
