i picked this up less than a week ago and have used it twice and can see a markable difference in my skin tone and quality.
it's not broken me out nor is it scary to use like some of those other systems are. there's no tool or anything to scrub your face; you use your fingers and i like that a lot better. seems safer on my skin.
i tend to have combination skin and have large pores on my cheeks and my skin has balanced out and the pores are visually smaller.
here's to hoping this keeps up!
