Autoimmune skin diseases occur when the immune system mistakenly attacks healthy skin cells, leading to inflammation, rashes, or other skin abnormalities. These conditions include psoriasis, which causes scaly patches; vitiligo, where pigment-producing cells are destroyed, resulting in white patches; and lupus, which can cause a characteristic butterfly-shaped rash. Some autoimmune skin disorders, like pemphigus, involve painful blistering, while others, like scleroderma, cause the skin to harden and tighten. While there is no cure, treatments like immunosuppressive medications, topical therapies, and lifestyle changes can help manage symptoms and prevent flare-ups. Regular monitoring by a dermatologist is essential for long-term care.
