Ive used it 3 times up to now and it removed most of my blackheads.The result is fast & amazing! Works phenomenally well on black heads, pimples, even the difficult and deep set blackheads. I consider my skin fairly clean to begin with, and I use face masks/exfoliants weekly. My first time using this tool i saw some disgusting things come out from my facial pores. That means it works. A bit too well unless you’re careful what you’re doing...my daughter didn’t listen and ended up bruising her face by leaving the device too long on her skin ... it’s quite addictive... my other half always suffers with the odd pimple on his back... not any more tho
