Definitely wouldn’t advise either. I know for sure that they ask not to use the fake tan before surgery, and re – sun bed, I personally wouldn’t advice as it dries your skin and add unnecessary stress especially as yous king will be stretching after the implants have been inserted.
P.s. – I do love sunbeams in general, just wouldn’t recommend before surgery to give your skin the best chances to adapt and recover without extra discomfort or even stretch marks.
Good luck on your surgery! x
