You should be able to buy professional scar removal products in pharmacies or hospitals. Your scar hasn't hurt your pores yet, but it will cost some money. Don't use scar-removing facial cleanser, it's bad for your skin. You should use a mild facial cleanser. If you wear makeup often in the future, you should prepare a bottle of cleansing oil. If you are still alive, you should spend some money. You'd better go to the hospital.
