I used to use a Sunbed when I was in my early 20's and I still had acne/spots on my face and the Sunbed treatment helped dry them up and go away.
It is good for that.
We used to have our own Sunbed, so that saves money
But today, I wouldn't use one, as I am not into sunbathing anymore and that is a bit risky, when you hear about the cracks in the ozone layer and skin cancers.
Obviously, the ozone layer doesn't apply to sunbeds. But for those who enjoy tanning themselves like that, they usually like the real sun as well.
