First of all, let me clarify that it contains a roller from 0.5 - 2mm as in the title, and not 0.2 as stated in the description. It is a typographical error.
I mistakenly asked for information about a similar product from the same supplier, thinking that I was addressing the store, so I never received a response.
If someone wants to buy any similar product, they should be aware that the 2mm is NOT for household use, no matter how daring they are.
The 0.5mm is ideal for the face (with 300 needles), for the body, if it is less than 750 needles, it is small and a pure hassle. No pain, no marks.
The 1mm is only for the body. BE CAREFUL, it doesn't seem to hurt during use, but shortly after application, the tingling starts, which lasts for 24 hours, and the marks remain for about 4 days (I have overly sensitive skin). Surely my movements were rather abrupt because I didn't feel any pain to notice, but regardless, I have read from experienced people that it only leaves marks for a maximum of 4 days.
A new machine every 6 months due to wear and tear.
I do not recommend, UNDER ANY CIRCUMSTANCES, using a needle larger than 1mm for household use.
I don't know if it does what it promises, but with all this sterilization hassle, it might be good to have reviews for the corresponding RF machines since they come at the same price and promise the same results but more comfortably.
Even on your vacations, you steal time and take care of yourself without sterilization and marks.
As for the ice roller, at least I didn't find it necessary and I don't use it.
Derma pen is not for beginners.
I hope I helped.
