It does depend......If you are a hard drinker, your body parts start to deteriate, ex: skin. If its like a champagne glass once in two months, then probably not.....Maybe a body's way of showing damadge is through spots. But, maybe its a skin condition and you should talk to your doctor about it:)
It's possible it could for you, if that's what you're experiencing. People have varying reactions to different things, and some things will cause some people acne and it won't in others. You'll probably be able to figure it out for yourself eventually.
Alcohol can cause bad skin not sure about spots, it normally effects you as you get older. But there could be a load of reasons causing bad skin.
I haven't heard anything confirming it...
Not that I know of.
