It gives a glow to the face in the following days of application and a smoother texture to the skin as if you have done exfoliation. Until there, satisfactory. It does absolutely nothing for wrinkles. I don't know if something more expensive would do what it promises.

Very good! A friend recommended me to get it and I mainly use it on my face, with slightly gentler pressure. It does the job... :-)

Very good. I believe that the 1.00mm is good for the body as it doesn't hurt almost at all and doesn't require numbing cream, something that might be necessary for rollers with longer needles. I chose this because I didn't want to risk injuring my skin. It leaves a redness for 2-3 days and I don't use any cosmetic lotion during this time. Just an antiseptic. I use it once a week (4 times so far) and I noticed a noticeable difference in the texture of my skin. It needs more time and patience though! I hope I helped.
