Redness, slight blistering, tenderness, and swelling are some of the most common side effects of laser tattoo removal. All patients experience these side effects to various degrees. Your skin will feel sensitive and tender for a few days, but these side effects should gradually dissipate over two weeks. You might also experience a “frosting” effect, which makes the treated tattoo look white and chalky, indicative of the release of carbon dioxide from the skin. This frosting effect should last for a maximum of 30 minutes — if it lasts longer, please contact your service provider.
