It works great!
Satisfying and disgusting to see all the funk it pulls out and all the little newly emptied pores. It's a mini vacuum cleaner.
And your face! Treat it accordingly! Of course, it can do damage. I used the silicone tip on low to learn how and what to do (and not to do). I used a hot wet towel repeatedly! Many many times every session! Heat opens pores up, cold closes them. It doesn't take long for that to happen.
Do not expect magic or miracles. Some things will take more than one session to work it out. Don't use it every day!
I love it!
