1. Psoriasis is a chronic autoimmune skin condition that affects the life cycle of skin cells, causing them to build up rapidly on the surface of the skin. The exact cause of psoriasis is not fully understood, but it is believed to involve a combination of genetic and environmental factors. It is not contagious and cannot be passed from person to person.

The appearance of psoriasis varies from person to person, but common signs and symptoms include:

- Red patches of skin covered with silvery scales: These patches, also known as plaques, are usually raised and can appear on any part of the body, but are most commonly found on the elbows, knees, scalp, and lower back.
- Dry, cracked skin: The affected skin may become dry, itchy, and prone to cracking or bleeding.
- Thickened, pitted, or ridged nails: Psoriasis can also affect the nails, causing them to become discolored, thickened, pitted, or ridged.
- Swollen and stiff joints: In some cases, psoriasis can also cause joint pain and inflammation, a condition known as psoriatic arthritis.

Psoriasis cannot be cured, but various treatment options are available to help manage the symptoms and reduce flare-ups. These treatments may include topical creams or ointments, phototherapy (light therapy), systemic medications, and lifestyle modifications such as stress reduction and avoiding triggers that worsen the symptoms.
