Here are the most common causes of acne that we have gathered for you.

Hormones- the number one cause of acne is the production of sex hormones called androgen that begins at puberty.   This is why majority of acne sufferers are adolescents and teens.  Hormones are responsible for then acne flare-ups during menstruation and pregnancy.

 When the sebaceous gland is stimulated by androgens, it produces extra sebum. In its journey up the follicle toward the surface, the sebum mixes with common skin bacteria and dead skin cells that have been shed from the lining of the follicle. While this process is normal, the presence of extra sebum in the follicle increases the chances of clogging — and acne.

Oily or heavy make up- Heavy make-up clogs the pores and oily make-ups add more oil, this only adds to the problem if oily skin already exists.  Cosmetics especially certain moisturizers, foundation and pomades (watch out for lanolin, petrolatum, vegetable oils, butyl stearate, lauryl alcohol and oleic acid).  

Certain medications and steroids. Vitamins are good for your body, But an excess of vitamins B1, B6 and B12 can cause acne flare-ups. These vitamins are good for the skin, but avoid overuse.

Diet- For some people, a diet that is high in refined carbohydrates and sugars can actually aggravate their acne. 

Over abrasive cleansing- Harsh exfoliators can damage skin and spread infections. 

Picking and squeezing- This can actually send the infection deeper into the skin and can cause scarring.
