Blisters are a normal reaction to tattoo removal, as is redness, especially in the Summer (although you will blister all year round)!
Blistering is a positive indication that the healing process is going as planned, and that the ink is being removed from your body. It is also normal for the blisters to burst, and means that the skin will heal faster.
Some patients may experience bruising or swelling, and many clients develop blisters, crusts or scabs within 8-72 hours, lasting for up to 2 weeks or more. The treated areas may be pale or pink after the scabs separate, and loss of pigment in the treated area may occur temporarily.
It is best to keep the dressing with ointment on and apply Ice packs to help keep cool.
