One of my friends asked me what blackhead treatment she should be using. So far I suggested many creams for her but none of them works. So I asked her about the kind of food she eats and from her diet, I already know that blackheads would never leave her. Then after hearing about her diet, I told her to shun foods that as so high in carbohydrates and fats. She should switch to eating fresh fruits, vegetables and raw fats such as avocadoes, olives, etc.) Being selective in the food you eat can reduce sebum production that clogs the pores thus causing blackheads. I also told her to wash her face always to keep her face clean and fresh from sebum always.
