Ace fell off the ugly tree and hit every branch on the way down.
I had the displeasure of meeting Ace about ten years ago. He is even uglier in person.

His makeup breaks him out
I dont need a disclaimer to get into heaven. I know Ive made mistakes, I dont need to be saved. -MIW

He had bad acne as well from the 70's.
A combination of that and age.
He had plastic surgery before the 95 reunion concert.
"We're all afraid of the dark inside ourselves."

1. Drinking/Partying
2. Bad aging
3. Broken face bones (from a looong time ago)
   But mainly the drinking for sure. However, he has grown a beard lately.
   "Is that you crawling up my stairs?"

I was wondering the sameprobably this is the result of years of hard partying+
bad plastic surgery (he had 2 bad car accidents due to his drinking problems)+
make up allergy.
