Article in English: Contact a doctor immediately if your skin is blistering from sunburn. This is a sign of severe sunburn that should be treated with personal medical advice, and the blisters put you at risk of infection. While waiting for an appointment, or if your doctor does not recommend any specific treatment, follow the precautions and general advice below. If your sunburn is serious, blistering "bubbles" of the skin may form. Do not attempt to pop them, and try to avoid rubbing or scraping them. Popped blisters can lead to infection and scarring. If you absolutely cannot function with the blisters intact, visit a doctor and ask to have them popped in a safe, sterile context. Wash your hands with soap and water before adding or changing dressings to prevent infection. Small blisters can be covered with an adhesive bandage (plaster), while larger ones can be covered with a gauze pad or surgical dressing, taped gently into place with medical tape. Change the dressing daily until the blister has gone. Consider using an antibiotic ointment (such as polymyxin B or bacitracin) on your blisters if you suspect infection. Infection might manifest as a foul smell, yellow pus, or extra redness and irritation around the skin. Ideally, visit a doctor to receive a diagnosis and advice specific to your symptoms. Note that some people are allergic to these ointments, so do a "patch test" on an unaffected area first and make sure you don't have a bad reaction. Do not tear off the flaps of skin left over from broken blisters. You'll shed them soon enough; don't risk irritating your skin even more now.
