I mean, when you think about it, it makes sense that ingesting chemicals can’t be good for you, but I had always opted for the spray tan thinking I was saving myself from skin cancer. While the risk from sun baking and tanning beds is no doubt much higher, this is a lesson that natural is always the healthiest alternative.
