Two good quality tools, stainless steel which can be therefore disinfected before and after use. I will not lie to you, it's pretty bad so use the evening after clean the skin and open the pores. After washed again, disinfected instruments and ESPECIALLY a good cream is put. My problem is not blackheads and pimples so I am used primarily follows the instrument that looks like a spatula. I, unwanted every 2 weeks in alternation with a conventional anti-buttons black patch. For now I see no big changes but will have to see over time.
