There are many factors that tend to cause acne.
Hormones and Sebum
It’s a fact that acne tends to be associated with teens. It affects over 85% of us during those years. It’s at that stage of life when hormone levels increase sharply.
Among other effects, those stimulate the sebaceous glands that produce sebum, the natural oil found in hair follicles. Increased oil or sebum isn’t generally a problem if it reaches the surface. It’s spread around, and often washed off with alcohol or soap and water by those who take good care of their skin. Still, blackheads may form as a result of the excess oil.
Stress itself doesn’t produce acne, but it can make it worse by increasing hormones. It also contributes to weakening the immune system, thus leading a less effective defense against invading bacteria. But it’s not a main factor.
Drugs
Certain drugs can promote the development of acne. Barbituates and tetracycline are known to be among the culprits. Anabolic steroids are broadly recognized by professional dermatologists to be a main contributor among those who take them. Forgoing these, except for specific medical purposes, helps reduce the odds.
Diet & Skin Care
Poor eating habits often go hand in hand with poor skin care practices. And, any food that tends to increase the production of sebum (oil) or certain hormones will have an effect.
But no study confirms that the common culprits – soft drinks, chocolate and greasy cheeseburgers, among others – play a large role in producing acne.
Poor cleansing habits play some role, because bacteria that lie near the surface sometimes remain ‘unmolested’. Regular use of a good cleanser can help. Take care that the skin doesn’t become excessively dry, however. That causes other problems.
Heavy dirt or even makeup can contribute to a problem by blocking the pore, especially if they block oil ducts.
Heredity
Genetics can cause acne as well. The area is one of active research, and therefore the exact mechanism isn’t detailed. But, statistics show that acne does tend to run in families. That may be partly due to diet or other common family circumstances.
