My artist told me to keep it out of direct sunlight for almost two months, but I don't know what your artist told you. If u do have to get it in direct sunlight u should put sunscreen on it. The sun makes the ink fade really really badly
It should not be exposed to sun while it is healing (2 - 4 wks), until it feels like regular skin, and does not hurt when u bump it. After it is completely and totally healed, u can go in the sun with high SPF sunblock (no less than 50 SPF) Do not use sunblock while it is healing because it will pull the color out. If u do not do this, it will fade. There is nothing worse for a tattoo, than the sun.
