Dear reader, you’ll find the video just a bit further down the page.
Acne, medically termed acne vulgaris, is a persistent skin disorder that develops when excess oil from the skin and dead skin cells block hair follicles.
Common characteristics of this condition include the appearance of blackheads or whiteheads, pustules, greasy skin, and the potential for scarring. It predominantly impacts areas of the skin with a higher concentration of oil glands, such as the face, upper chest, and back.
The visible effects of acne can contribute to feelings of self-consciousness, nervousness, diminished confidence, and, in severe instances, emotional distress.
The predisposition to acne is largely hereditary, with genetics playing a role in approximately 80% of cases.
The influence of diet and tobacco use on this condition remains uncertain, and neither hygiene practices nor sunlight exposure are linked to acne development. In both men and women, hormones known as androgens are a key factor in the condition’s underlying cause, as they trigger increased sebum production.
Another contributing element is the overgrowth of the bacterium Cutibacterium acnes, which naturally resides on the skin.
