The development of acne is multifactorial. It involves follicular hyperkeratinization (exfoliating or shedding skin cells from a plug within a pore,) hormonal influences (androgens or sex hormones that signal sebum or oil production,) and inflammation related to bacteria. To put it simply, acne symptoms, like red, raised lesions can occur when too much oil and dead skin cells or bacteria clog a pore, which initiates an inflammatory response from the body, resulting in breakouts. More detail, below:
Excess sebum
Sebaceous glands, which are located at the end of a hair follicle, or pore, produce sebum, which is an oily substance designed to keep the skin healthy by hydrating it and protecting it from external stressors. Sometimes, these glands can go into overdrive and produce too much oil, which can result in clogged pores, and eventually, breakouts.
Hormones
Those sebaceous glands become triggered mainly by hormones. Acne tends to be hormonally driven. The same hormones that drive acne also tend to promote more oily skin. Which hormones are mostly responsible for increased oil production? Androgens are the main drivers of acne. Androgen levels tend to rise in adolescence and, especially in women, in early adulthood.
Dead skin cells
It’s not just oily skin that leads to acne symptoms—debris like dead skin cells can contribute to clogged pores, causing breakouts.
Diet
While highly disputed as an official cause, many believe that what they eat has a direct impact on the condition of their skin. A high glycemic index diet is thought to be related to acne. These types of foods cause large increases in blood sugar levels, which leads to the release of hormones that may promote acne formation. Some examples of high-glycemic foods include white bread and sugar.
