The rocker fell asleep while using the artificial tanning machine and severely damaged his skin leaving him barely able to move.
Ozzy said: "I once went to a tanning salon, turned the machine straight up to 10 and passed out on the bed. I woke up a few hours later looking like I'd been hit by an atomic bomb! I was furious with myself for months because I could hardly walk - never mind smile, bend over or do anything that involved creasing even the tiniest part of my skin. I might as well have paid someone to throw me in a bath of acid."
The 61-year-old singer - who is married to TV star Sharon Osbourne - believes no one should succumb to the lure of tanning booths and should instead just be happy to be pale.
He added: "It ages you by decades, too. A few doses of the hard stuff and you'll end up with a face like an antique football. I recommend avoiding anything with UV rays and settling for the pale and interesting look."
