I am a paramedical tattoo artist. We use a saline solution in place of pigment when we are touching up areas and need the pigment to lighten. This is sterile and medical grade saline from the medical supplier. We also use this when the patient has an adverse reaction to a pigment such as; itching, edema or any other discomfort. This method irrigates the area by depositing the saline into the healed tattoo. The saline then flushes out the pigment during the healing process. It can take as many as three sessions. It is the same discomfort of a tattoo. The same procedure. The only difference is saline solution is being used in place of pigment. The healing process is the same as well. It works well. Topical numbing can be used to avoid discomfort. Applied 45 minutes prior and wiped off during prep. It lasts 90 mins from the time you wipe it. Standard procedure for going on 10 years now.
