Just my 2 cents, my artist puts on plastic film and says keep it on for 4 hours, then take it off and give it a good wash, but do NOT put any cream on for 48hours, only wash it every couple of hours. The cream he recommends to me is bepanthene, it’s a nappy rash cream, and apply it 3 times a day with a very thin layer, what I keep forgetting to ask him is for how long should I use it, but I kinda use it for three or even four weeks just to keep the skin moisturized. What do people think of that aftercare. I have had 4 tats with that artist and im happy with the out come of the tattoo. BTW I have thick skin because I got a tattoo with a different tattoo artist recently(much to my regret) and he said that I have skin like a rhino, and I have never got a skin infection either.
