The blister will probably remain intact, although some burns units at hospitals follow a policy of deroofing blisters. Deroofing means removing the top layer of skin from the blister. This is known as aspiration and may be carried out on large blisters or blisters that are likely to burst. Your healthcare professional will advise you about the best way to care for your blister and what type of dressing you should use.
During the first few years after a burn, you should try to avoid exposing the damaged skin to direct sunlight as this may cause it to blister. It's especially sensitive during the first year after the injury. This also applies to a new area of skin after a skin graft. It's important to keep the area covered with cotton clothing. If the burn or scald is on your face, wear a peaked cap or wide-brimmed hat when you're out in the sun.
Total sun block for example, one with a sun protection factor, SPF, of 50 should be used on all affected areas. Apply cool compresses to burns on the face or body. Do not use ice or ice water, which can cause tissue damage. Take off any jewelry, rings, or clothing that could be in the way or that would become too tight if the skin swells.
Clean the burn Wash your hands before cleaning a burn. Do not touch the burn with your hands or anything dirty, because open blisters can easily be infected. Do not break the blisters. Gently wash the burn area with clean water. Some of the burned skin might come off with washing. Pat the area dry with a clean cloth or gauze. Do not put sprays or butter on burns, because this traps the heat inside the burn. Bandaging the burn If the burned skin or blisters have not broken open, a bandage may not be needed.
If the burned skin or unbroken blisters are likely to become dirty or be irritated by clothing, apply a bandage. Our Housecall e-newsletter will keep you up-to-date on the latest health information.

You may choose to cover small blisters with a plaster. Larger blisters can be covered with a gauze pad or dressing that can be taped in place. Painful blisters, or those in positions where they're likely to burst, such as on the sole of your foot, can be covered with a soft dressing to cushion and protect them.
It may help to cut the dressing into a 'doughnut' shape to fit around the blister and avoid placing pressure directly on it. If a blister has burst, don't peel off the dead skin on top of the blister. Allow the fluid inside to drain and wash it with mild soap and water. Cover the blister and the area around it with a dry, sterile dressing to protect it from infection until it heals.
Hydrocolloid dressings, available over the counter from pharmacies, have been shown to help prevent discomfort and encourage healing. If the top layer of dead skin from a burst blister has already rubbed off, don't pick at the edges of the remaining skin. Follow the advice above to protect it from infection. Blood blisters should be left to heal naturally. If a blood blister bursts, keep the area clean and dry. Protect it with a sterile dressing to prevent infection.
Blood blisters are often painful. Applying an ice pack to the affected area immediately after the injury can help relieve the pain a bag of frozen vegetables works just as well. Between 10 and 30 minutes should help. To stop the ice touching your skin directly, place a towel over the affected area before applying the ice pack. Blisters are more likely to develop on moist skin. If you have sweaty feet, wearing moisture-absorbing socks or changing your socks twice a day can help prevent them.
If you play sport or exercise regularly, wearing sports socks or thicker wool socks can help keep your feet dry and reduce your risk of getting a blister. Dusting the inside of your socks with talcum powder may also help.
If you're going for a long walk, wear comfortable shoes that fit properly. Brand new shoes that aren't broken in may not be comfortable and may rub. Stop immediately if you feel a hot area on your foot while walking, exercising or playing sport. If possible, tape some padding over the area. Wear protective gloves when using tools such as shovels or pickaxes, and when doing manual work such as gardening.
