Psoriasis is a chronic autoimmune skin condition that causes the rapid buildup of skin cells, resulting in scaling, redness, and inflammation. It can affect people of all ages and typically appears on the skin's surface. Here are some key points about psoriasis:

1. Types: There are several types of psoriasis, including:
   - Plaque Psoriasis: The most common form, characterized by raised, red patches covered with silvery-white scales.
   - Guttate Psoriasis: Presents as small, red, scaly spots, often triggered by infections like strep throat.
   - Inverse Psoriasis: Occurs in skin folds, such as under the breasts, in the groin, and in armpits, appearing as smooth, red lesions.
   - Pustular Psoriasis: Characterized by pus-filled blisters surrounded by red skin.
   - Erythrodermic Psoriasis: A rare but severe form that causes widespread redness, scaling, and shedding of the skin.

2. Causes: Psoriasis is an autoimmune condition, and its exact cause is not fully understood. It is believed to involve a combination of genetic and environmental factors, as well as an overactive immune system.

3. Triggers: Psoriasis symptoms can be triggered or worsened by factors such as stress, infections, certain medications, and injury to the skin.

4. Treatment: Psoriasis is a chronic condition without a cure, but it can be managed effectively. Treatment options include topical creams, phototherapy (light therapy), oral medications, and biologic drugs. The choice of treatment depends on the type and severity of psoriasis.
