Acne, including the adult and hormonal kind

Acne, including the adult and hormonal kind: this guide covers comedonal, inflammatory, nodulocystic, adult jawline acne in women, back and chest, acne…

This guide is general education, not a diagnosis or an individual treatment plan. Urgent, severe or worsening symptoms belong with the local emergency service or a qualified clinician.

What this guide covers

This guide covers comedonal, inflammatory, nodulocystic, adult jawline acne in women, back and chest, acne after stopping the pill, PCOS-linked acne, acne scars and post-inflammatory marks (which fade and which do not), plus a plain ladder of what has trial evidence — benzoyl peroxide, adapalene, azelaic acid, topical and oral antibiotics with the resistance rule, combined pill, isotretinoin and what the monitoring involves — and an evidence-graded page on dairy and high-glycaemic diets.

One focused section asks: "Jawline acne in your thirties: what it usually is". Nothing is diagnosed; Each section names when a dermatologist or GP is the next step.

How to use it

Start with the description that most closely matches your question about Acne, including the adult and hormonal kind. Use the evidence section to understand what is known, then use the boundary section to decide when self-education should stop and clinical care should begin.

The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.

Search vocabulary in four languages

Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.

Evidence and provenance

The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.

Source: European evidence-based (S3) guideline for the treatment of acne (Nast et al., JEADV, open access), Cochrane acne reviews (cited), glycaemic values from the apex glycaemic-load hub. · checked 2026-09-09

Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.
