Let me make you very clear from the beginning that blackheads do not occur due to dust or pollution. Annoying and stubborn blackheads are caused due to the blocking of pores by excess sebum and dead skin. As the sebum and dead skin are exposed to the air, they start to oxidize and turn into black color.
Scrubbing face regularly to get rid of blackheads is not a good option. There are many more ways to get rid of them according to your skin type. Use some of the ways discussed below twice or thrice a week and get a blackhead free face.
People with darker skin should avoid this tip as it can discolor your skin.
