I have done many microdermabrasion treatments in the past. I have never had bruises after the treatment. I have visible bruises on my checks, nose and chin. When I asked the lady after the treatment, I have been told that this is normal. In my opinion, the treatment might have been done aggressively and perhaps more training is needed. It is annoying for me because now I need to cover up when I go out next few days until they are healed otherwise people will start questioning what happens.
