What is the best way to heal a blister?

Protective Mechanism: When there is injury to our skin, inflammation occurs which means the area becomes red, warm, tender and with swelling. The swelling occurs under the skin layers and causes them to bulge creating a protective fluid cushion we call a blister. As the area heals, the fluid will be resorbed or when no longer needed, the blister opens and the fluid drains. This should take about a week.

Protect it: An unpopped blister represents a closed sterile environment. Yes on occasion one can become infected then it is time to open it, however the risk of infection in a dressed open wound is still higher than that of an intact blister. The blister will gradually resolve with time.
