This powder is essential for filling in pores on the nose. I bought it after seeing it recommended by Hiro Odagiri. After applying sunscreen, I apply this powder with a brush to areas where I have pores, but before applying my foundation. I also apply Canmake's Poreless Primer to my nose to thoroughly fill in the pores. Given my age, I think it would be difficult to do without laser treatment or something, as my pores are sunken, but this powder primer is extremely excellent and gives me the best finish of all the ones I've tried.
