I found a coupon for a Microdermabrasion in my current city. I got kind of nervous because it was at a spa instead of a Dr's office. I read online to be careful with microdermabrasion and suggested going to a place w doctor supervision but I went along with it anyway. It said certain places don't recycle crystals as they should and there's a risk for HIV and HEP C. Here's the worst part, the young girl (who later told me she had just started working there) was very clumsy and at one point rubbed the crystal apparatus against herself bc she said the machine gets jammed sometimes and then immediately started using the apparatus on my face again. I researched later that the crystals kind of shoot out and then get sucked back in to the apparatus. During the procedure, the apparatus in essence sandblasts your skin. I feel that most likely there are tiny cuts created especially when your skin has pimples, etc, and I had a few cuts on my face from shaving just an hour earlier as well that could've easily been re irritated (kind of like when you scratch a scab). So, if there are warnings for making sure equipment is sanitized and the "specialist" and I essentially shared the equipment, am I at risk for HIV or HEP C? I am really nervous after sleeping on it and maybe I should've spoken up while I was there. I have no idea what her status is but that's still a huge risk for me. Assuming she had HIV or HEP C, am I at a great risk? Please help because I am extremely worried! Should I take PEP? I also don't want to put my wife or family at risk!
