It's like a cat's tongue touching your face. This is how my aesthetician explained what I was about to experience with Microdermabrasion.
I would say that at first it was a bit shocking. Not painful, but not like a cat licking my face. That is kind of a cool feeling. The areas that I had some acne scarring on my chin were a bit sensitive and then on the sides of my face it felt kind of nice. She did a bit on my chest and when I got out of the shower and looked in the mirror I could see the red lines where my skin was sloughed off. She said that she did it on the lowest setting till I get used to the feeling and to see how my skin responded to the first treatment.
Overall, I enjoyed the experience. My skin feels great and I will go back to get a few more treatments to lighten the hyperpigmentation on my chin and some new "freckles" cause I don't want to call them age spots on the side of my face
