What the pattern can and cannot tell you

The AAD describes predictable period-related breakouts and persistent lower-face acne as clues that hormones may play a role. Other causes can look similar, and a photograph cannot confirm hormone levels or rule out another skin condition. Keep a simple note of when flares occur and what treatments you have tried before a consultation.

Acne is not a hygiene failure. Scrubbing, repeatedly switching products and layering many acids can make irritation worse without treating the underlying process. A gentle routine is a better base for judging whether an active is helping.

Evidence-informed options

The AAD acne guideline supports topical benzoyl peroxide and retinoids strongly, with conditional support for salicylic and azelaic acids in appropriate situations. These ingredients do different jobs and do not need to be piled on at once. Follow local directions and allow time for a treatment to work.

For some adults with stubborn hormonal acne, a dermatologist may consider prescription options such as combined oral contraceptives or spironolactone after reviewing medical history and pregnancy considerations. Those decisions require a clinician; an app should never recommend or dose them from a selfie.

When to get help sooner

Deep painful nodules, scarring, widespread inflammation, sudden severe changes or major distress are reasons to seek professional care. If pregnancy is possible, discuss treatment choices before starting a retinoid or prescription medicine. An ingredient scan can help you understand a product, but it cannot establish the cause of acne.

Project Glow's planned beta will connect concerns, ingredient evidence and product labels with uncertainty visible. It is a learning tool, not a replacement for medical assessment.

Frequently asked questions

Is jawline acne always hormonal?

No. It can be a clue, but location alone cannot diagnose a hormonal cause.

Can over-the-counter skincare fix hormonal acne?

Some evidence-supported acne treatments may help, but persistent or severe cases can need prescription care.

Should I stop all moisturiser if I break out?

No. A suitable moisturiser can help support tolerance of acne treatment; choose a texture that suits your skin.
