Is self-tanner harmful in anyway?

my swag (scientific wild as guess) is not that i am aware of. is use this gun type thing from walgreens (havent been able to but it anywhere else but there) its called Salon Bronze as an veteran tanner who uses suncreen in the actual sun most days at Cocoa Beach or Daytona, this works pretty well for a nice glow. vaseline intensive care makes a tanning lotion too. that works well occasionally. tanning beds are better for you then the sun. over using and putting burn on top of burn from a bed is how people get the misconception that beds are just as bad as sun. the bulbs in a bed block out the harmful UV-A. and as the latest book i have read Survival of the Sickest, we need some sun to produce vitamins for our kidneys and liver. i learned one other thing from this book that some folks may not know, is that wait a few minutes before reentering the sun before putting on your sunglsses.you eyes tell you brain to tell your skin to up the melanin in your skin so you tan instead of burn. makes sence to me. im sorry i went above your question, but maybe this may help others with a few bed and sun topics.
