Acne is a very common skin condition, but its familiarity should not make it easy to dismiss. Spots can be uncomfortable, leave lasting marks and affect confidence well beyond the teenage years. The condition develops when hair follicles become blocked by oil and dead skin cells. Changes in the activity of skin bacteria and the local inflammatory response then contribute to blackheads, whiteheads, inflamed spots, nodules or cysts.
Acne most often affects the face, chest and upper back, where there are many oil-producing glands. Hormonal changes during puberty are a frequent trigger, although acne can begin or persist in adulthood. Family history, some medicines, pregnancy and hormonal conditions can also influence it. It is not caused by dirty skin, and repeated scrubbing is more likely to irritate than to help.
Recognising acne and seeking help
Mild acne generally consists of blackheads, whiteheads and a limited number of inflamed spots. Moderate acne is more widespread, while severe acne can include painful nodules or cysts and carries a greater risk of scarring. A pharmacist can advise on mild acne. A GP should assess acne that is moderate or severe, is causing scarring, has not improved with pharmacy treatment, or is having a significant effect on emotional wellbeing.
Sudden acne in an adult woman can occasionally be associated with a hormonal imbalance, particularly when it occurs alongside irregular periods or increased facial or body hair. These features deserve medical assessment rather than dietary self-treatment.
Everyday skin care
A gentle routine is usually the most useful starting point. Wash acne-prone skin no more than twice daily with lukewarm water and a mild cleanser. Choose moisturisers, cosmetics and sunscreens labelled non-comedogenic or oil-free, and remove make-up before bed. Picking or squeezing lesions can deepen inflammation and increase the likelihood of scarring.
Exercise does not treat acne directly, but it supports general health and mood. Shower after vigorous activity because sweat and friction can aggravate sensitive skin. Keep oily hair products away from the face and clean items that regularly touch the skin, such as make-up brushes, glasses and mobile phones, without turning hygiene into an anxious or excessive routine.
Evidence does not support a single prescriptive “acne diet”. NICE advises that there is currently insufficient evidence to recommend a specific diet as a treatment. A varied, balanced eating pattern remains sensible for overall health. Some people notice that particular foods coincide with flare-ups, but an isolated episode does not establish cause and effect. A short record of food, menstrual cycle, stress, sleep, medicines and skin changes can be more informative than removing several food groups at once.
If a dietary pattern is very high in sugary drinks, confectionery and highly refined carbohydrates, improving its overall quality is reasonable. Build meals around vegetables, fruit, pulses, whole grains where tolerated, good-quality protein and unsaturated fats. This supports general nutritional adequacy without promising that food alone will clear the skin.
Treatment takes time
Effective acne treatment often requires patience. Pharmacy treatments may include benzoyl peroxide. Prescription options include topical retinoids, azelaic acid, antibiotics and, for some women, hormonal treatment. Severe or treatment-resistant acne may need referral to a dermatologist. Several treatments take two or three months to show a worthwhile effect, so using them consistently and following professional instructions matters.
Some acne medicines increase sensitivity to sunlight or are unsuitable during pregnancy. Oral isotretinoin is a specialist treatment with important safety and monitoring requirements. Supplements should never be used as a substitute for prescribed treatment or to counteract side effects without checking with the treating clinician or pharmacist.
A balanced perspective
Acne is a genuine inflammatory skin condition, not a sign of poor cleanliness or personal failure. Good nutrition can support general health and help someone maintain a stable routine, but it should sit alongside appropriate skin care and evidence-based medical treatment. Early advice is particularly valuable when painful nodules, scarring or low mood are developing.
