Skin problems refer to a wide range of conditions that affect the skin, the body’s largest organ, which serves as a protective barrier and regulates temperature and hydration. These conditions can include rashes, infections, acne, eczema, psoriasis, dermatitis, allergic reactions, fungal infections, warts, skin growths, or injuries such as cuts and burns. Symptoms vary depending on the specific problem and may include redness, itching, swelling, pain, flaking, blistering, discoloration, or lesions. Causes can range from infections, allergies, autoimmune responses, environmental exposures, genetic factors, or trauma. While many skin problems are mild and self-limiting, persistent, widespread, or severe symptoms may require medical evaluation to identify the underlying cause and prevent complications.
