What is Psoriasis?
Psoriasis is an autoimmune disease characterized by patches of abnormal scaly skin. These patches are typically red, dry and itchy. Most people find them irritating and they can be a cosmetic concern.
Patches usually appear on the scalp, elbows, knees, or nails and are more apparent during winters when heat and humidity increase (imagine flaky dandruff). It mainly occurs due to malfunctioning of the immune system, which causes rapid production of skin cells leading to an irregular build-up of dead skin cells in these areas where they pile up, forming the thick patches/scales.
