Adult Acne: When Skincare Is Not Enough and What Your GP Can Actually Prescribe

Last updated: 2 November 2026

Nobody warns you that you can leave your teens, build a career, perhaps have children, and still be hiding a chin full of spots behind your hand on a Zoom call. Adult acne is common, it is under treated, and it is surrounded by two unhelpful ideas: that it is caused by poor hygiene, and that the right cleanser will fix it. As an NHS GP I see women every week who have spent hundreds of pounds on skincare for acne that needed a prescription, and as an aesthetic doctor in Hale I see the marks and scars that months of delay leave behind.

This article is the conversation I would like to have with each of them. It covers why adults get acne, how to tell when skincare is not enough, exactly what your GP can prescribe (according to the national guideline), when you should be referred to a dermatologist, and where a skin clinic fits, which is afterwards, for the marks and scars, not instead. The order matters more than almost anything else in acne, because scars are permanent and spots are not.

How common is adult acne?

Far more common than the teenage stereotype suggests, and far more common in women. A study of 1,013 adults aged 20 and over, published in the Journal of the American Academy of Dermatology, asked people simply whether they had acne.

Age group Women with acne Men with acne
20 to 2950.9%42.5%
30 to 3935.2%20.1%
40 to 4926.3%12.0%
50 and over15.3%7.3%
"Our findings demonstrate that acne is a persistent problem for people of all ages." Dr Julie Harper, lead author, Journal of the American Academy of Dermatology, 2008.

So if you are 38 and still breaking out, you are one of roughly a third of women your age. That matters because adult acne is a medical condition with effective, evidence based treatment on the NHS, not a personal failing to be managed quietly with concealer.

Why do adults get acne?

The mechanics are the same at any age: oil glands over produce, the pore lining sheds abnormally and blocks, bacteria multiply in the trapped oil, and the follicle inflames. What differs in adults is what drives it, and the driver decides the treatment.

Driver How it tends to look What it means for treatment
Hormonal fluctuationDeep, tender spots on the jaw, chin and neck that flare in the week before a periodTopicals help; hormonal treatment from your GP often helps more
PCOS (now PMOS)The same pattern plus irregular periods, excess hair or thinning, dark neck patchesNeeds diagnosing; treating the condition treats the acne. See my guide to PCOS and your skin
Stopping or changing contraceptionAcne appearing three to six months after coming off the combined pill, or starting a progestogen only method, implant or hormonal coilOften settles within a year; your GP can discuss options if it does not
PerimenopauseBreakouts in the forties alongside dryness and sensitivity, as oestrogen falls faster than androgensGentle regimes matter; HRT sometimes helps, sometimes not; a GP conversation
Stress and poor sleepFlares in bad weeks; cortisol increases oil and inflammationReal but rarely the whole story; treat the acne while you work on the rest
Products and habitsSmall bumps and blackheads on cheeks and hairline from heavy creams, oils, hair products, pillowcases, phones, pickingThe one cause skincare changes really do fix
DietWorse with high glycaemic eating and, for some, whey protein and skimmed milkWorth adjusting; see how your diet could be causing breakouts
Medicines and supplementsSteroids, some epilepsy and mood medicines, high dose B12 and biotin, testosterone, some protein powdersTell your GP everything you take; never stop a prescribed medicine for your skin without advice
Not acne at allUniform itchy bumps on forehead and chest (fungal folliculitis), or redness with bumps but no blackheads (rosacea), or spots only around the mouth (perioral dermatitis)Each needs different treatment, and acne products make two of them worse; a GP can tell them apart

How to get the most from a GP appointment about acne

Ten minutes goes quickly, and acne appointments often end with the first cream on the list. This is how to make yours count.

Do this Why
Bring photographs of your skin at its worst, including any scarsAcne is always better on the day of the appointment; photos show severity and scarring, which drives referral
Write down everything you have tried, for how long, and what happenedTwo failed 12 week courses is a referral criterion; your GP cannot count courses you do not mention
Describe the pattern: where, when in your cycle, how long marks lastA hormonal pattern changes the treatment choice
Mention periods, hair, weight change and family historyPCOS is diagnosed from exactly these details, and treating it treats the acne
Say how it is affecting youPsychological impact is a referral criterion in its own right; GPs cannot act on what you do not say
Ask for the 12 week review to be booked before you leaveThe guideline runs on reviews; the commonest failure is a prescription that is never followed up

What should your skincare look like during treatment?

Prescription treatment works best on calm, uninflamed skin, and the main job of skincare during acne treatment is to make the prescription tolerable rather than to treat the acne itself.

Step Do Avoid
CleanseTwice a day with a gentle, non foaming or low foam cleanser; lukewarm water; pat dryScrubs, brushes, hot water, "squeaky clean"; stripped skin makes more oil and tolerates treatment worse
TreatYour prescribed treatment exactly as directed, to the whole area, not just spots; a pea sized amount for the faceLayering shop bought acids, retinols or benzoyl peroxide on top; one active at a time
MoisturiseA light, non comedogenic moisturiser every day, and more if the retinoid dries you; niacinamide and ceramides are usefulHeavy oils, coconut oil, rich balms; "oily skin does not need moisturiser" is a myth that worsens retinoid irritation
ProtectBroad spectrum SPF 30 to 50 every morning, light gel or fluid texturesSkipping it; retinoids and antibiotics increase sun sensitivity, and UV is what turns a red mark into a brown one that lasts a year
Make upNon comedogenic, mineral or light fluid foundations; clean brushes weeklySleeping in it; thick, long wear formulas during a flare
HandsOff. A hydrocolloid patch overnight on a spot you cannot leave aloneSqueezing deep spots; it is the single commonest cause of the scars I later see

Medical grade skincare has a role here, chosen for the stage you are at: barrier support and SPF during treatment, then pigment control and a maintenance retinoid afterwards. What it is not is a replacement for the prescription ladder above. I will say that to anyone who asks me to "fix" active inflammatory acne with a product.

Where does a skin clinic fit? Marks, scars and the order of things

I run a skin clinic, so you might expect me to put it higher up this article. It belongs here, after the medical treatment, for a simple reason: treating marks and scars while new spots are still forming is painting a wall that is still being knocked down. Once acne has been quiet for a few months, this is what I can do.

What is left behind What helps Timing and expectations
Red marks (post inflammatory erythema)Time, SPF, azelaic acid or a retinoid; they fade over three to twelve months on their ownPatience is the main treatment; I do not offer laser, which is the clinic option for stubborn redness
Brown marks (post inflammatory hyperpigmentation)Daily SPF, prescription strength retinoids and pigment regulators, superficial peels such as the Obagi Blue Peel Radiance; the Obagi Nu-Derm programme following consultation for extensive marksMonths, not weeks; darker skin tones need gentler, slower approaches to avoid making it worse. See marks left after spots
Rolling and boxcar scarsA course of medical microneedling, with exosomes where appropriate, usually three sessions four to six weeks apartImprovement, not erasure; acne must be quiet and oral isotretinoin finished for at least six months first
Ice pick scarsThe hardest type; microneedling helps a little, and some need specialist techniques I do not offerI will say so at consultation rather than sell a course that will disappoint
Texture, pores and dullness after years of acneRetinoids, peels, polynucleotides for skin qualityOften the most satisfying stage, because the skin is finally allowed to be well

The whole of this article comes down to a sequence. GP first, for the diagnosis and the guideline treatment. Gentle skincare alongside, to make the treatment tolerable and protect against marks. Dermatology if you scar or do not respond. A skin clinic last, for what the acne left behind. Done in that order, most adult acne can be controlled and most of its marks improved. Done in reverse, with peels on active acne and prescriptions never requested, it costs more and scars more. At my clinic in Hale I would rather tell you to see your GP first and treat your scars properly in six months than take your money now.

Takeaway: scars are permanent and spots are not. Get the prescription early, protect the skin while it works, and bring me the marks afterwards.

Frequently asked questions about adult acne

Why do I have acne at 35 when I never had it as a teenager?

Adult onset acne is common in women and is usually hormonal: cyclical fluctuations, PCOS, stopping the pill, a progestogen only contraceptive or early perimenopause. A GP can help work out which, and treat accordingly.

Is adult acne caused by poor hygiene?

No. Acne is driven by oil production, pore blockage, bacteria and inflammation, all influenced by hormones and genetics. Over washing makes it worse by stripping the barrier and increasing oil.

What is the best over the counter treatment for adult acne?

Adapalene 0.1% gel, a retinoid now available from pharmacies, and benzoyl peroxide are the two with real evidence. Give them twelve weeks with a gentle cleanser, moisturiser and SPF. If that has not worked, or you are scarring, see your GP rather than buying more products.

Can my GP prescribe tretinoin for acne?

Yes, usually as a fixed combination gel with clindamycin, or adapalene combined with benzoyl peroxide, as part of a 12 week course under the NICE guideline. These are prescribed for acne by your GP; at my clinic prescription retinoids are used for skin quality and pigmentation following consultation, not as acne treatment.

Why has my GP only given me antibiotics?

Oral antibiotics alone are not recommended by NICE; they should always be combined with a topical treatment, reviewed at three months and rarely continued beyond six. It is reasonable to go back and ask for the guideline combination.

Does the pill help adult acne?

Often, yes, particularly for jawline acne that flares before a period. Some combined pills are licensed for acne. Suitability depends on your medical history, which is why it is a GP decision; allow three to six months to judge.

When should I be referred to a dermatologist?

If your acne is scarring, leaving persistent pigmentation, causing persistent distress, if the diagnosis is uncertain, or if two 12 week courses have failed. Severe nodular acne should be referred early. Use the word "scarring" and ask directly about referral criteria.

Is isotretinoin dangerous?

It is a powerful medicine with real side effects, including dryness, mood effects that need monitoring and absolute pregnancy prevention, which is why only a consultant dermatologist led team can prescribe it. It is also the most effective treatment for severe or scarring acne, and under proper supervision most people complete it safely.

Does diet cause adult acne?

Diet does not cause acne on its own, but high glycaemic eating and, for some people, whey protein and skimmed milk make it worse. Lower glycaemic eating helps the insulin pathway that drives oil production, especially in PCOS.

Can I have a chemical peel or microneedling while I have active acne?

Superficial peels can help mild congestion, but inflamed acne should be treated medically first, and microneedling should never be done through active spots because it spreads inflammation. I treat marks and scars once the acne has been quiet for a few months.

How long after isotretinoin can I have microneedling or peels?

Most guidance is to wait at least six months after finishing, as the skin heals differently in that time. Your dermatologist's advice takes precedence, and I check before treating anyone who has had it.

Next steps

If your acne is active, start with your GP; take this article with you if it helps. If it has settled and you are left with marks, scars or skin that feels tired after years of breakouts, I would be glad to see you for a consultation at the clinic in Hale and plan the next stage properly.
