Blisters heal on their own within 1 to 2 weeks.
Blisters take roughly 7-10 days to heal and usually leave no scar.
However, they can become infected if exposed to bacteria.
So avoid popping the blister as it could spread bacteria and make it worse and take longer.
If you don't pop a blister, it remains a sterile environment, virtually eliminating any risks of infection.
Blisters develop to protect damaged skin and help it heal.
They're mostly caused by friction, burns and skin reactions, such as an allergic reaction.
Blood blisters appear when blood vessels in the skin have also been damaged.
Some ways to get rid of a blister and help the blister heal faster are.
Wash your hands and the blister with soap and warm water.
Swab the blister with iodine.
Sterilize a clean, sharp needle by wiping it with rubbing alcohol.
Use the needle to puncture the blister.
Apply an ointment such as petroleum jelly to the blister and cover it with a nonstick gauze bandage.
Blisters are fluid-filled sacs on the outer layer of your skin.
They form because of rubbing, heat, or diseases of the skin.
They are most common on your hands and feet.
Other names for blisters are vesicles (usually for smaller blisters) and bulla (for larger blisters).
