(Question) Is Agnes effective for blackheads?

I am worried because I have severe blackheads and whiteheads. I use sebum softeners regularly, but they only remove the sebum while the blackheads remain in my pores, which looks terrible. Agnes treatment is usually recommended for blackhead removal, so I am curious to hear reviews from people who have actually received it. Does the Agnes treatment actually remove blackheads? Does it not include pore-shrinking benefits? How painful is it? I am also curious about the duration of the results and the number of treatments required.
