Peeling skin is a condition where the outer layer of the skin starts to replace itself, often as a result of damage from environmental elements, skin conditions, allergies, infections, or certain diseases and treatments. It can also be a sign that your skin is healing from some type of damage, such as sunburns, allergies, skin diseases, or treatments for cancer, acne, and aging. Some of the common causes of peeling skin include:

• Sunburns, wind, heat, dryness, and high humidity
• Allergies and skin-to-skin contact with something you are allergic to
• Skin diseases, such as eczema, rosacea, and psoriasis
• Infections, including some types of staph and fungal infections, scarlet fever, and impetigo
• Immune system disorders
• Cancer and cancer treatment

Peeling skin can also be a symptom of more serious conditions, such as genetic diseases, Kawasaki disease, and acral peeling skin syndrome. It is important to see a healthcare provider to evaluate your symptoms and perform tests (if needed) to determine the underlying cause of peeling skin. This ensures you start the right treatment to stop your skin from peeling.
