In most cases, no. The intact skin over a blood blister acts as a natural barrier against infection. Popping it increases the risk of bacteria entering the wound and can slow healing.

If a blood blister bursts on its own:

Gently clean the area with soap and water

Apply an antiseptic

Cover with a sterile bandage

Keep the area clean and dry
