It doesnt necessarily work VERY well- I tried various timing and methods of how I used it and surprisingly I found that when i used it directly after my 10 hour work shift (before washing my face) I got the most gunk out. In fact, when I use it after I shower and clean my face and my skin softens up, I dont get as much. It definitely doesnt solve my issue of blackheads at all (no pore strip will) but its still addicting to see a few come out for fun. I will say, as someone with super sensitive skin, this product did not irritate my skin AT ALL or make me break out which is surprising to me because I was a little worried about how it smells like glue/paint. Also, I my mom accidentally threw away the rest of the paper it comes with and using a single sheet of toilet paper gave me the same exact effect even though I look silly af. Even though it doesnt take as many blackheads out, I still prefer this over the biore strips because its a lot more uses for less money. I usually put this stuff all over my face, whereas the biore strips only have specific precut shapes they give you. Overall, I definitely recommend trying it!!
