Acne Causes – What Causes Acne?

Acne, more commonly referred to as blackheads or pimples, affects the skin in various ways. It typically manifests itself by plugging pores which contain hair follicles and oil glands causing blockages within them.

Sebum production leads to inflammation and the formation of acne lesions such as papules, papules topped with pus, or cysts (nodulocystic acne). Unfortunately, its cause remains elusive but appears to involve several factors.


Many assume acne is simply a rite of passage during teenagehood and expect it to go away when braces and school dances have ended, yet many find their acne persisting into adulthood, or even appearing for the first time as adults. Unfortunately, it can still present itself at this age!

Acne is caused by overproduction of sebum (oil produced in hair follicles), combined with accumulation of dead skin cells in pores. When this happens, pores become blocked with debris and an infection occurs; leading to papules, nodules and cysts that lead to inflammation.

Teenagers frequently experience hormonal fluctuations that contribute to acne, such as androgens which increase during puberty in both boys and girls and cause sebaceous glands to produce more oil. Once hormone levels stabilize in adulthood, acne may still occur due to factors like diet, stress and medications – anything which applies prolonged pressure such as helmet chin straps can worsen acne symptoms further.


Acne is a hormonal condition caused by changes in hormones. Androgen hormones increase during teenage years and cause sebaceous glands to produce too much oil (sebum), leading to overproduction which in combination with dead skin cell build-up leads to pores becoming blocked and acne flare-ups.

C. acnes is a normal bacteria on your skin that thrives under these circumstances and quickly multiplies. This results in red bumps known as pimples or lesions forming; typically blackheads, whiteheads and papules; though in rare instances cysts and pustules may form too.

Hormonal acne typically appears on the face, neck, shoulders, chest and upper back due to high concentrations of hair follicles and oil glands in these areas. Diet, hair care products that clog pore or promote oil production such as heavy makeup and some steroid drugs may worsen this form of acne while stress, menstrual cycles or oral contraceptives may also contribute.


Many people with acne believe diet has an enormous effect on their condition. Making changes to one’s diet could help clear existing breakouts as well as prevent future ones, and keeping a food diary will allow them to identify which foods trigger or worsen their acne before consulting with a registered dietitian for personalized advice.

Studies have linked a diet high in Glycemic Index (GI) and Glycemic Load (GL), such as processed foods or sweet beverages with increased acne severity. This could be because such foods cause blood sugar spikes which in turn causes insulin production and oil production increases, thus exacerbating acne symptoms.

Dairy-based diets may also contribute to acne, though this could be more about their glycemic index (GI) rather than fat content. People suffering from acne should look for foods like fish and nuts with lower glycemic index ratings to reduce their acne risk and consume more omega 3 fatty acids which contain anti-inflammatory benefits while drinking green tea which contains polyphenols which have antibacterial properties.


One generation ago, many believed that eating greasy or sugary foods would contribute to acne breakouts. While greasy food may make your skin oilier, acne itself is caused by clogged hair follicles due to excess sebum production and accumulation of dead skin cells; hormonal fluctuations or medications may further aggravate symptoms.

Your diet could play a vital role in combatting acne by including more low-glycemic foods like fresh fruits and vegetables along with whole grains – while avoiding high-glycemic processed food such as corn flakes, white bread, donuts and milkshakes which contribute to high levels of sugar intake.

Avoid applying greasy makeup, skincare products and sunscreens on acne-prone skin as this will clog pores and worsen acne symptoms. Cleanse twice a day using mild soap or cleanser in warm water with two rounds of facial washing using mild soap as this may increase scarring risk; alternatively wear loose fitting headbands/hats when sweating heavily to prevent further staining along hairlines.
