The causes of acne are multifactorial. The exact cause of acne has never been identified, and it is thought that several interrelated factors can cause acne. It's perhaps because we are often unable to determine the root cause of acne in individuals that statistics of this skin condition are so shocking.
The causes of adult acne and the causes of cystic acne are particularly difficult to determine. 17 million people in America alone have acne.
If you are between 12 and 25 years old, you are among the 85% of people who suffer from acne.
25% of men and 50% of women suffer from acne during their adult life
Here are some of the external and internal factors that have been linked to acne in any way or from another.
External Contributors to Acne  Make-up and Skin Care Products
Comedogenic skin care products may cause irritation or break out. These include all the products that clog the oil ducts. Look for non-comedogenic or non acneic products, but be aware that these products can still make you break out.
Depending on where you work, it is possible that your work environment may cause acne. Such environments include manufacturing or construction facilities where you can come in contact with chemicals or pollutants that cling to the skin.
Too much sun
Evidence shows that another exposure to the sun's rays is one of the many causes of acne. This can even cause acne a few months after exposure
Moisture can cause the follicular cells to swell moisture. On the other hand, dry air can create thick sebum inside the follicular cells. Both extremes can ultimately cause acne.
Picking and Squeezing Pimples
Touching your face or using your fingers to pick or press buttons is one of the simplest causes of acne that are more common. Picking pushes bacteria deeper into the skin cells or spreads bacteria already beneath the surface of the skin
The sweat trapped by your clothes creates an ideal breeding ground for bacteria. Friction caused by pressing or rubbing on the skin or the pressure of bicycle helmets, backpacks or tight collars can contribute to the worsening of acne.
In-house contributors to acne
a contributor to acne. The bacteria known as Propionibacterium acnes are responsible for the appearance of acne. These bacteria create enzymes that dissolve oil in the skin and irritate the skin causing inflammation.
In general, there is a relationship between the amount of sebum produced and the severity of acne. The largest sebaceous glands are located on the face, neck, chest, upper back and upper arms.
Sometimes the walls of follicles grow abnormally and can cause acne. In addition, increased cell growth can interfere with the follicles and form a plug. This plug grows up to burst and spread the bacteria to the surface of the skin.
Many causes of acne come from a hormonal change or imbalance. There are hormonal changes during stress, menstruation, pregnancy, stop / start of contraceptive pills, menopause and hormonal disorders
Androgens: Androgens are produced by the adrenal glands, one of the internal causes of acne that boosts oil production. . The increase in androgen levels leads to more acne.
Stress: Although stress does not directly cause acne, it will aggravate it. This is because stress leads to increased levels of androgens, which then affect your sebaceous glands.
Dermatologists are still not 100% sure if what we eat affects acne. There is an ongoing debate among experts on the role of food.
Prescription Drugs and Steroids
Certain medications, including lithium, barbiturates and steroids such as bodybuilding (androgens), are known to cause acne. Genetics
If your parents had acne, or any of them, there is a chance that you will inherit their complexion. It is now believed that acne can work in the family, but the specific genetic factor has not been discovered.
As you can see, there are many causes of acne that can be both independent or interdependent. It is almost impossible to separate the interconnection activities that contribute to acne. Being aware of these causes of acne can help you minimize rashes.
