What is Acne Vulgaris?
While acne is often seen as a cosmetic issue, its effects go beyond just the appearance of the skin. For many people, acne can cause emotional distress and impact self-confidence, especially if left untreated.
The severity of acne can vary, with some individuals experiencing only mild breakouts, while others may deal with persistent and painful flare-ups that affect both their skin and their quality of life.
Medical Definition
Acne vulgaris is a chronic inflammatory skin condition that occurs when hair follicles become clogged with oil (sebum) and dead skin cells, leading to the formation of comedones, papules, pustules, and in severe cases, nodules and cysts.
- Affects the pilosebaceous unit (hair follicle and sebaceous gland)
- Involves four main pathogenic factors: sebum production, follicular hyperkeratinization, bacterial colonization, and inflammation
- Most commonly appears on face, chest, and back where sebaceous glands are most active
- Can range from mild comedonal acne to severe nodulocystic acne
- Often begins during puberty but can persist into adulthood
