Aloe Vera
Aloe vera gel contains numerous antioxidants that help reduce inflammation and thus reduce the redness, swelling and pain linked with blood blisters. These antioxidants can also help repair the damaged skin and make the blisters heal faster. Also, aloe gel has potent antimicrobial activities that can keep infections at bay. Cut a fresh aloe vera leaf to remove its gel. Apply the gel over the blister 2-3 times a day.
