Skin conditions can range from mild irritations to severe infections. Common causes include allergies, infections, and chronic conditions like eczema or psoriasis. Symptoms vary but often include redness, itching, swelling, and sometimes pain. Diagnosis typically involves a physical examination and may include skin tests or biopsies. Treatment depends on the cause and can include topical creams, oral medications, and lifestyle changes. Good skin care practices, such as moisturizing and avoiding irritants, can help prevent many skin issues. If you experience persistent or severe symptoms, it's important to consult a healthcare professional for proper diagnosis and treatment.
