Why does it keep coming back?
Androgens, hormones including testosterone, stimulate oil production. Excess oil mixes with dead skin cells and bacteria inside pores, triggering swelling and pain. Hormonal acne often appears as inflamed or deep bumps on the chin, jawline and lower cheeks, particularly before a period. A cycle related flare can last days or weeks.345
Hormone changes during pregnancy, the transition to menopause, and menopause can also trigger adult acne. Starting or stopping birth control can change the pattern. Family history matters too, so a persistent problem is not necessarily something your skincare routine caused.6
What could be making it worse?
- Stress and lack of sleep can contribute to hormonal breakouts.
- Greasy skincare and haircare products can contribute to blocked pores.
- Picking, squeezing and scrubbing can worsen acne or cause scars.
- Some medicines, including steroids, can contribute. If you suspect a prescription, keep taking it and speak to the prescriber about alternatives.
Look for skincare and haircare labels such as "oil free" or "noncomedogenic", meaning formulated not to clog pores. Those are more useful shopping criteria than a small novel about transformation.6
Could there be an underlying hormonal condition?
Polyendocrine metabolic ovarian syndrome, or PMOS, can increase androgen levels, causing more oil production and slower skin cell turnover. Acne that persists despite standard treatment, especially alongside increased facial or body hair or scalp hair thinning, is worth discussing with a clinician. Acne's appearance alone cannot diagnose PMOS; assessment can include hormone tests or an ultrasound.2
What should I do now?
- 1Note when breakouts flare, including their relationship to your period, medication changes, stress and sleep. Bring those details to an appointment.
- 2Wash morning and evening with a gentle cleanser, remove makeup at night and use a moisturizer alongside acne treatment. Avoid scrubbing.
- 3For mild acne, ask a pharmacist about benzoyl peroxide or salicylic acid. Benzoyl peroxide reduces acne associated bacteria; salicylic acid helps clear dead skin cells from pores. Lower strength benzoyl peroxide and wash formulas are less irritating.
- 4If topical treatment is not enough, discuss prescription options. These include retinoids, antibiotics, hormonal treatment and, for appropriate severe cases, isotretinoin.
Do I need hormonal treatment?
Combined birth control pills containing estrogen and progestin can reduce hormonal acne. Spironolactone reduces the effects of hormones on excess oil production. Neither is suitable for everyone: estrogen containing contraception needs a medical suitability check, and spironolactone must not be taken during pregnancy. If you are pregnant or planning pregnancy, get treatment advice before choosing acne medicines; topical retinoids and isotretinoin should be avoided during pregnancy.1245
Choose acne treatments by their active ingredients, rather than marketing vocabulary, which has never been short of ambition.5
How long should I wait, and when should I get help?
Initial improvement can take four to six weeks; retinoids often need several months. Apply a prescribed acne retinoid across the affected area, not just individual spots. If birth control has not started helping after about six months, discuss other options.134
Do not wait through a treatment trial if you have deep, painful lumps, scarring or acne affecting your mental health. Seek medical assessment for hot, swollen, red skin suggesting infection, or sudden severe adult acne. A dermatologist can also help when acne keeps worsening or does not respond to treatment.37
