Laser treatments target areas of mild to moderate skin psoriasis. You'll need several sessions and may have some bruising or burning. Psoriasis can also be treated with ointments, lotions, creams, foams, shampoos, prescription pills, shots, and IV infusions.
Another option is phototherapy (light therapy), where you expose your skin to ultraviolet light. The UV light can slow the growth of affected cells. You first have treatments at a doctor's office. Your doctor might have you follow up with a portable light at home.
