Acne Vulgaris — Conditions

What is Acne Vulgaris?

The most common form of acne, presenting with a combination of comedones, papules, and pustules

Triggered by increased sebum production due to puberty-related hormonal changes, which leads to clogged pores and bacterial proliferation.

Main causes & characteristics

The core mechanism is thought to involve increased androgen hormone levels during puberty stimulating the sebaceous glands, leading to excess sebum production. This is compounded by the excessive buildup and blockage of keratinocytes at the pore opening, within which Cutibacterium acnes proliferates and triggers inflammation — giving rise to a combination of comedones, papules, and pustules. Genetics, stress, and insufficient sleep are also cited as aggravating factors.

How to manage

It is recommended to cleanse gently twice daily with a mildly acidic cleanser and to manage sebum and dead skin cells using products labeled non-comedogenic. Squeezing blemishes by hand is best avoided, as this may lead to scarring or post-inflammatory hyperpigmentation. If papules or pustules spread widely or become painful and recurrent, consulting a dermatologist is recommended.

Good to know alongside

Commonly associated topics include comedones (blackheads and whiteheads), sebaceous glands, hair follicles, post-inflammatory hyperpigmentation (PIH), and acne scars. Adult acne is known to differ from adolescent acne in terms of location and presentation.

Everyday care tips

Keeping pillowcases and phone screens clean regularly, reducing intake of highly processed foods and excessive dairy, and maintaining consistent sleep habits may all help.
