My parents bought this for me on a whim because I was complaining about blackheads. At first, I was highly skeptical as the DermaSuction seems super gimmicky, but it totally works! The first time I used it was in the middle of the day without anything done to my skin beforehand. The instructions say to be careful and not leave it in one spot for too long, but I thought "what's the worst that can happen" and jumped right into it. I used the highest suction, left it in place for a few seconds, and went over the same areas multiple times (like the box said NOT to do...) and ended up with hickeys on my face. Bad times.
After a few days, the bruising from my stupidity was gone, and I decided to try it again. After taking a hot shower to open up my pores, I followed the instructions (not leaving it in one spot longer than 1-2 seconds) and got quite a bit of nasty sebaceous oil and gunk out of my skin! It did leave my skin slightly red for about 10 minutes following the suction, but that went away and my skin was back to normal.
It does take a few uses until you get noticeable results, but as long as you follow the instructions it actually works!
Bottom Line: Yes, I would recommend this to a friend
