Psoriasis Q & A

What is psoriasis?

Psoriasis affects about 2.2% of Americans, and it's the most common autoimmune disease in the US today. Psoriasis is a chronic inflammatory condition that causes:

  • Itchy skin
  • Red raised patches
  • Silver-white scales


The most common areas for psoriasis to develop are the scalp, elbows, knees, and lower back. However, it can appear nearly anywhere on your skin or nails. If you have nail psoriasis, you may have pits on your nails. Eventually, your nails may thicken and turn yellow as they separate from the nail beds.

Psoriasis symptoms may be worse when it's cold and dry but improve in warmer weather.

How is psoriasis treated?

The skin experts at Z-ROC Dermatology offer a variety of psoriasis treatments, depending on your individual case. Your treatment typically starts with the most conservative option first: topical ointments.

Although topical treatment alone may be enough for many psoriasis sufferers, some patients need extra help in the form of oral biologic medication, oral retinoid medication, light therapy, or a combination of these approaches.


Biologics come from a living organism like a plant or animal cell. They’re often made through recombinant DNA technology. Biologics target the cells causing your body’s immune response, and in the case of psoriasis, this means disabling the cells causing the excessive cell growth.


Retinoids are oral or topical medications that work by helping your skin shed dead cells at a normal and healthy rate. Retinoids are most effective when combined with light therapy.

Light therapy

In light therapy, your dermatologist treats your psoriasis patches with controlled doses of UVB light. Although light therapy can help with psoriasis on its own, it usually works best in combination with biologics or retinoids.

Can my psoriasis go away permanently?
