hi tests,
yes, some of those white gunk lurking on my nose can be easily rub off. But the majority of them are embedded deeply inside my pores and these requires a lot more strength to rub them out. And I often rub to the point where my nose turns Red before they are willing to come out...
The scissor-tweeze is just 1 alternative for me to pull them out gently (It's surprising that some of these gunks have pretty long roots inside the pores

). Anyways, I have also read that salicylic acid is good at dissolving these gunks but I havent try it yet
