Psoriasis is a life-long immunologic condition where skin grows new cells too fast, and shedding does not occur, thereby forming a buildup of scaly lesions. According to the PsoriasisNet website, there is no cure.
Types
Lasers offer a unique treatment option called “targeted phototherapy," sparing healthy skin from ultraviolet light. The excimer laser concentrates the light only on the psoriasis lesion, allowing high doses of laser light for rapid clearing. Another type of laser, called the pulsed dye laser, penetrates the skin and kills the blood vessels that help psoriasis form, notes PsoriasisNet.
Mechanism
The excimer laser causes breakage of DNA strands in T lymphocytes, causing a decrease in epidermal, or skin proliferation.
Benefits
The article, "Guidelines of Care for the Management of Psoriasis and Psoriatic Arthritis", by Alan Mentor, MD, claims that experts feel the excimer laser is safe in the pregnant and pediatric populations.
Side Effects
Adverse effects are limited to the treated area. Side effects of laser treatment include erythema, or redness, burning, hyperpigmentation and blistering on higher doses, claims the American Academy of Dermatology article.
Warning
Many states currently do not regulate who can perform laser treatments. Treatments should be administered by a board certified dermatologist or a person under the direction of the dermatologist, claims the PsoriasisNet website.
