Hi thank you for your question! Having facial hair will not interfere with having a microdermabrasion done in anyway. Make sure you go to someone who is qualified such as a Licensed Aesthetician.
Microdermabrasion is a procedure done by our skin care expert in our skin care clinic. I have seen lots of very good results and you can consult with your local skin care expert.
I would wait 2 weeks before having microdermabrasion, as this is the healing time after microneedling. If your skin still feels sensitive then wait a full 4 weeks.
