Blistering is more likely when removing tattoos with cover-ups so it is important to tell your laser operator if you have cover-ups.
The ink underneath may react differently. There is a higher chance that there may be blistering in that area if the underlying ink absorbs the energy and cant release the heat as fast as normal.
How can that be you ask. Say you had black ink and the tattoo artist put white on top and then put red on top of that. Now you have 3 or more layers of different colors of ink in the same area. Each area may have more that one layer of ink. So potentially there can be a large amount of ink in the area. Those multiple layers of ink may hold heat in and slow down the release of heat. That can increase the chances of blistering in that area.
The ink underneath is not visible, if you don’t tell the operator won’t know.
What are your options. If you don’t want to blister then you should discuss this with the doctor and or laser technician who is about to treat you – BEFORE they begin. The laser power can be set lower that otherwise generating less energy less heat and smaller amount of ink fragmented. So it would take more laser sessions.
If you do blister never ever pop a blister. Protect it and let it take its time naturally. Some people use Aquaphor on blisters. Its always more comfortable to not get a blister.
Cover ups can blister more easily unless the power is lowered. Discuss the pros and cons.
Best advice keep a picture of your tattoos before you get cover-ups so you can bring them with you before doing laser tattoo removal. The more information you provide the more accurate the evaluation can be.
