Skin disease refers to a variety of conditions that affect the skin, which is the body's largest organ. These diseases can cause symptoms like rashes, itching, redness, and swelling. Common types include eczema, psoriasis, and acne. While some skin diseases are temporary and can be treated easily, others may require ongoing management and care. Many factors can contribute to skin diseases, including genetics, allergies, and environmental influences. Proper skincare, a healthy diet, and avoiding irritants can help maintain skin health. If someone experiences persistent skin issues, it's important to consult a healthcare professional for diagnosis and treatment options.
