I popped mine and no scars left. Only you have to press really hard. If you don't see anything then keep pressing anyway, eventually they pop and there's green stuff coming out of them.Blackheads, how to get rid of them...?
try to apply lemon juice mix with water be careful don't use pure it will irritate your skin but once or twice a week would be good. i do it with mine but i know the dose so i do everyday with care, otherwise i mash avocado make a paste out of it and apply on my face, keep it for at least 45 minutes to 1hour if i am not in hurry. eggs is good too. yoghurt as well.
Make sure you wash your face everyday with a cleanser that contains salicylic acid. I also recommend Biore Pore Strips once a week to keep blackheads under control.
use Biore pore Strips. They work great and you can buy them at any drug store.
