You’re supposed to wait a year, but a lot of girls go back sooner, remember that the high uv can cause you to tan blotchy, and your incisions to become red and raised.
If you are to go back on, use a uv blocker on your incisions (not normal sunscreen, as it isn’t made to use against the high uv a bed produces) and cover your whole boobs for at least the first three months (don’t go on before your six week check hunny)
If you need to tan, you can use a build up moisturiser, but keep it off your incisions (having it, or any type of tan that requires washing off can stain your incisions, leaving then oddly coloured) xx
