What is psoriasis?

Psoriasis is a condition in which you produce too many skin cells, and they accumulate on your skin surface. There are many different types of psoriasis, and they can all cause frustrating and embarrassing skin problems. 

What kind of psoriasis do I have?

Each type of psoriasis has its own distinct symptoms.

Plaque psoriasis

Plaque psoriasis affects 80-90% of all psoriasis sufferers. If you have plaque psoriasis, you'll typically have thick, dry, and inflamed skin patches called plaques. Often, plaques are covered by scaly while or silver skin. Usually, plaque psoriasis occurs on your elbows, knees, lower back area, and scalp. 

Guttate psoriasis

Guttate psoriasis causes small red spots that usually appear on your torso, arms, and legs. This type of psoriasis can turn into plaque psoriasis sometimes. Guttate psoriasis usually occurs because of a specific triggering event, like a bout of strep throat or some other kind of infection. 

Inverse psoriasis

Inverse psoriasis usually occurs in the places where your skin touches frequently, like under your arms, below your breasts, or in the groin. Inverse psoriasis is shinier and smoother than other types of psoriasis. Inverse psoriasis sufferers often have another kind of psoriasis, too.

Pustular psoriasis

Pustular psoriasis causes small pus-filled circles on the palms of your hands, heels, fingers, or toes. The pustules can grow together, and they might then develop scales that look more like other forms of psoriasis.

Psoriatic arthritis

Psoriatic arthritis is an autoimmune disease that causes painful joints. You may have significantly swollen skin, especially in your hands and feet, and your nails may flake or develop pits.

Erythrodermic psoriasis

This rare form of psoriasis causes your skin to grow inflamed in large areas, and it can peel off in sheets. It causes intense redness and can be dangerous or even life-threatening.

Dr. Feinsod examines your skin and considers your symptoms to determine which type of psoriasis you have so he can design the ideal treatment solution.

How is psoriasis treated?

Psoriasis treatment depends on your symptoms and how it’s affecting you. For many patients, the XTRAC laser is very effective for psoriasis. The single-band ultraviolet B light prevents your skin cells from replicating further to stop new plaques from forming. 

Treatments are only a few minutes each, and the laser doesn’t damage your healthy skin, either. 

XTRAC laser treatment can also be a great solution for vitiligo, in which your skin loses pigmentation in blotches.
