oily skin is mainly caused by bad food. Meat [greasy; barbecue] or sweets like chocolate, or ice cream.





i get rid of blackheads by washing my face with Clearasil Ultra [3 days] with warm water,


dry my face,


and apply a layer [not to thin, not to thick] of Elmers Glue on the area that has the most blackheads. it works a bit because it


sticks the dirt and stuff.What causes oily skin? i have some blackheads?
The best thing for you is to control your diet. If you eat a lot of oily staff and chocolate etc.. you should reduce and try to eat more vegetable and fruits. Good luck
