Hi. I've had oily skin type since my puberty that I have lots of pores on my face nowdays. But I have no money as I'm a student so my choice is just microneedling 1. How long should I adjust the needle size for my pores?(When I used 0.8mm, there happened some red spot, blood.) 2. How long should it take?(Detailed methods, plz.) 3. I have torn scar below my eye. In this case, I wanna ask the same question(No. 2, 3) 4. Can the pores filled even if there're black heads in it by MTS?
