Five myths about acne

Acne is one of the commonest skin conditions — up to 85% of adolescents have some degree of it — and one of the most myth-ridden. Here are five widespread beliefs, checked against the page on acne vulgaris.

1. "Acne means you don't wash enough"

False, and it is the myth that does the most harm. Acne is a medical condition, not a hygiene problem. It arises from four factors together: excess sebum, follicular hyperkeratinisation, colonisation by Cutibacterium acnes, and inflammation.

Washing more makes it worse, because it irritates the skin and damages its barrier.

2. "Acne is a teenage thing"

False. It usually starts at puberty (12–18), but adult acne is increasingly recognised, particularly in women between 25 and 45. In adolescence boys tend to have more severe forms; in adulthood women are more often affected.

3. "Just be patient, it goes away"

Partly true, but risky. Many cases do improve with time — but treating early can prevent scarring, and acne scars are far harder to treat than the acne itself.

If over-the-counter products have not worked after 2 to 3 months, see a dermatologist.

4. "If it hasn't worked in two weeks, it doesn't work"

False. Results usually take 6 to 12 weeks. Consistency matters more than the product: a treatment applied irregularly cannot work.

5. "Isotretinoin is dangerous"

It's more nuanced. Isotretinoin needs careful monitoring and is reserved for severe or treatment-resistant acne — but it can give long-lasting remission. It is not a last resort to be avoided at all costs; it is a serious treatment with clear indications.

The details are on the isotretinoin page.
