Adult Acne: Causes and Treatment Options

Acne is not only a teenage problem. Many adults develop breakouts for the first time in their twenties, thirties or later, or find that acne returns after years of clear skin. It is driven by the same basic process as teenage acne, often with hormones, products, stress and medications playing a larger role, and it usually responds to a combination of consistent skincare and medical treatment.

What is happening inside a breakout

Acne develops in hair follicles, the tiny openings commonly called pores. Four main factors are involved:

• Oil glands producing more sebum than usual
• Skin cells shedding unevenly and plugging the follicle
• Bacteria that normally live on the skin multiplying in the blocked pore
• Inflammation, which turns a plug into a red, tender spot

Blackheads and whiteheads are non-inflamed plugs. Red bumps, pustules and deeper, painful nodules or cysts reflect more inflammation and are more likely to leave dark marks or scars.

Why acne shows up in adulthood

Adult acne often has a different pattern from teenage acne. In women it frequently appears along the jawline, chin and neck and may flare around the menstrual cycle. Common contributors include:

• Hormones: androgen hormones stimulate oil glands. Fluctuations around periods, pregnancy, perimenopause, stopping or starting hormonal contraception, and conditions such as polycystic ovary syndrome (PCOS) can all trigger breakouts.
• Stress and sleep: stress hormones may increase oil production and inflammation, and many people notice flares during demanding periods.
• Products: heavy creams, some hair products and oily makeup can block pores. Look for "non-comedogenic" on labels.
• Friction and pressure: masks, helmets, phones and tight straps can cause breakouts where they rub.
• Medications: some medicines, including certain corticosteroids, lithium and some hormonal treatments, can cause or worsen acne. Do not stop any medication on your own; speak with your prescriber.
• Family history: a tendency to acne often runs in families.

Adult acne can also be frustrating because skin may be dry or sensitive at the same time as it breaks out. Strong products designed for oily teenage skin can leave adult skin irritated without clearing spots, so a gentler routine is often a better starting point.

The role of diet is still being studied. Some research suggests high-glycemic foods and dairy may affect acne in some people, but the evidence is mixed and no single diet works for everyone.

When to see your family doctor

It is worth seeing your family doctor or a dermatologist if acne is painful, leaving scars, affecting your mood or not improving after a few months of over-the-counter care. Sudden severe acne, or acne along with irregular periods, unusual hair growth or scalp hair thinning, may point to a hormonal condition that needs investigation.

It is also important to make sure the problem is acne. Rosacea, perioral dermatitis and folliculitis can look similar but are treated differently, and some acne products make rosacea worse.

Topical treatments

Treatments applied to the skin are the foundation of care for most mild to moderate acne. Common options include:

• Benzoyl peroxide, which reduces acne bacteria and can bleach towels and fabric
• Salicylic acid, which helps unclog pores
• Adapalene and other topical retinoids, which normalise cell shedding and prevent new plugs
• Azelaic acid, which helps with acne and dark marks and is often gentler
• Topical antibiotics, available by prescription and usually combined with benzoyl peroxide to reduce resistance

These products can cause dryness, redness and peeling at first. Using a gentle cleanser and moisturiser, and introducing one product at a time, improves tolerance. Our article on retinoids covers how to start them slowly. Most treatments take about two to three months to show their full effect.

Simple daily habits that help

Alongside treatment, a few everyday habits can reduce flares. Cleanse gently morning and night, use a light non-comedogenic moisturiser and wear daily sunscreen, since sun exposure can deepen the dark marks acne leaves behind. Change pillowcases regularly, clean your phone screen, and keep hair products away from the forehead where possible. Avoid picking, which prolongs healing.

Prescription medical options

When acne is moderate to severe, or topical treatment is not enough, your doctor may discuss oral options. These can include certain oral antibiotics for a limited period, hormonal contraceptives for some women, spironolactone (a medication that blocks some androgen effects), or oral isotretinoin for severe or scarring acne.

These medications are effective for many people but have important side effects and precautions. Isotretinoin and spironolactone in particular are not used in pregnancy, and isotretinoin requires reliable contraception and monitoring. Decisions about these medicines belong with your family doctor or dermatologist.

How peels and laser can support treatment

In-clinic treatments can complement, but not replace, medical acne care. Superficial chemical peels with salicylic or glycolic acid may help clear clogged pores and improve the look of mild breakouts and dark marks; see chemical peels explained. Some laser and light treatments may reduce inflammation or improve texture and redness left behind by acne.

Once acne is well controlled, laser resurfacing may be considered for scarring. Peels and laser are usually postponed during active, inflamed or infected breakouts and for a period after oral isotretinoin, as advised by your doctor. Risks include irritation, temporary flares, pigment changes and, rarely, scarring.

Frequently asked questions

Should I squeeze my spots?

Try to leave them alone. Squeezing pushes debris deeper, increases inflammation and raises the risk of dark marks and scars. A spot treatment and patience are safer.

Does washing more often help?

Not usually. Washing twice a day with a gentle cleanser is enough. Over-washing or scrubbing can irritate the skin and make acne look worse.

Will acne go away on its own?

Some adult acne settles with time, but much of it is persistent or comes and goes. Treating it early reduces the chance of lasting marks and scars.

Can I wear makeup with acne?

Yes. Choose non-comedogenic, oil-free products and remove makeup gently every night.

Getting acne under control

Adult acne is common and treatable, but it often takes a combination of patience, the right products and, sometimes, prescription treatment. Starting with your family doctor makes sense if acne is persistent, painful or scarring.
