Repost Need advice: microdermabrasion/glycolic peels

Please girls I need your advice if you have had either one of these treatments before.

Does it hurt?
Would you recommend it?
What are some possible bad side effects?
Did you see a difference?

Any other information you can give I would greatly appreciate it.

I really do not have bad skin. I just keep breaking out in my chin area and the doctor suggested I do both of these like 3 times each. I just would like some more information before I do it.

TIA
