Psoriasis is a condition in which skin cells build up and form scales and itchy, dry patches. It is usually found on the elbows, knees, and scalp but can often affect the legs, trunk, and nails. While primarily seen in adults, it can occur in all age groups.
The most common form, affecting about 80-90 percent of psoriasis patients, is plaque psoriasis. It is characterized by patches of raised, reddish skin covered with silvery-white scales. Psoriasis flare-ups can last for weeks or months and can go away and then return.
There are many treatments for psoriasis including topicals, safe light treatments (NB-UVB), oral medication, and safe systemic biologic medications to significantly improve this chronic inflammatory skin condition.
