Honestly speaking acne is very common, very few people did not experience having acne at one point of his or her life. Acne is primarily hormones driven. Acne are most prevalent when a person is on puberty. But some person does not experience it while on puberty but experience later in their adult life.
Washing face frequently does not guarantee you to be acne free. If you got hormonal imbalance, there is a greater chance that you will have acne. According to ABB, acne differs from person to person some experience mild acne with just few bumps, blackheads and whiteheads. Some experience medium acne with a little bit more acne and some swelling ones. And there are severe ones, this type is like a cocktail of swelling and non-swelling bumps together with blackheads and whiteheads. These things grow everywhere face acne, mouth acne, even back acne.
There are so many factors that affects the blossoming of your acne. One is stress, when a person is under stress the body releases some hormones and, in this release, may in turn affect your acne. But this not entirely true for all people. Some may be affected, and some may not. Another one is food, if you eat too much oily food this will affect your acne. Some food is known to make acne worse like peanuts and other nuts.
