How to get rid of acne?

Tell me if you know how to get rid of acne, I have got so acne all over my face. I washed my face often and apply the lotion and moisturizer but the acne still growing. Why is that?

I seldom eat fried food and spicy food and the acne is not going away. Tell me is acne your problem too?

The type of acne I am having is blackheads and whiteheads. The blackheads can turn to dark sport.
