There are many hygienic measures that tattoo artists have to watch. You must be welcomed in a very clean lounge where very few people are traveling. The tattooist must clean his work environment, his hands and the tattooed area. He must use disposable equipment (needles, gloves) and sterilize the non-disposable material.
After this antiseptic wash, the tattooist must touch only the necessary to tattoo. A tattooist in full realization should not be able to pause his performance to make an appointment.
Ask your tattooist the hygiene precautions he applies in his living room and if you hesitate, ask him to see how he sterilizes his equipment.
First of all, even if it seems difficult for some, you should not touch the tattoo during the first day. Put a sterile compress on your skin to prevent it from coming into contact with anything. From the second day you can apply ointment on your tattoo over a period of eight days. Remember to wash, rinse and dry the tattooed area before each operation. Do not scratch the crusts formed on your tattoo. The ink could leave with them. Let them fall on their own. Finally avoid UV exposure and have your tattoo checked two weeks after completion.
Afterwards if you protect your tattoo when you are in the sun the color and the black hold as well as the other.
