Psoriasis is a chronic immune-mediated skin condition that causes the skin to produce new cells much faster than normal. Instead of developing over weeks, skin cells form within days and build up on the surface, creating thick, inflamed patches called plaques.
At OC MedDerm Dermatology in Irvine, CA, psoriasis is diagnosed and treated by Dr. Parvin Shafa, an experienced dermatologist specializing in medical and immune-based skin conditions.
