Psoriasis is a chronic autoimmune skin condition that causes rapid skin cell proliferation, leading to thick, red, scaly patches on the skin. It is often characterized by flare-ups that can occur in the same areas over time, influenced by genetic and environmental factors.
Autoimmune diseases occur when the immune system mistakenly attacks the body's own cells and tissues. This can lead to a variety of health issues, and treatments often focus on suppressing the immune response.
