Top Five Astonishing Facts about Blood Blisters You Absolutely Need to Know

Blood blisters are common occurrences that, despite their unsettling appearance, aren't usually cause for concern. A blood blister, unlike your typical blister, is filled with blood rather than a clear fluid. They generally develop after a skin trauma, when blood vessels and the epidermis layer of the skin are damaged, but not ruptured. Blood then accumulates beneath the skin's surface, resulting in the distinctive"bubble" appearance. But, beyond these basics, what are some astonishing facts about these odd skin occurrences?

Vulnerable Locations for Blood Blisters

One isn't completely random in where they can expect a blood blister to form. They tend to arise on skin that experiences regular friction or pressure, most commonly on the hands and feet. For example, if you've ever worn a tight pair of shoes for too long, you might have seen one or two on your feet. Surprisingly, the mouth is also a susceptible location, due to frequent exposure to hot food and accidental biting. Therefore, being mindful of these vulnerable locations can help prevent blood blisters.
