After your tattoo removal procedure, keep the treated area clean and dry. Use soap and pat the area dray. Blistering can occur 8 hours after treatment, this is not a cause for concern and actually indicates that your immune system is working to heal the area.
Cool compresses can be used after 24 hours to reduce discomfort and inflammation. The skin should not be scraped because this can lead to scarring or infection. You can resume showering 2 hours after treatment.
