Acne treatment in Singapore where to start, matched to the type and severity of your acne

Acne treatment in Singapore: how to use this guide

Acne starts in the hair follicle and its oil gland. Four things usually work together: oil glands making more sebum under the influence of hormones, dead skin cells plugging the pore, acne bacteria multiplying in the blocked space, and inflammation. Effective treatments act on one or more of these, which is why combining treatments that work in different ways tends to do better than a single product.

Acne is very common here. A local study found that 88% of adolescents aged 13 to 19 reported having acne, and in a Singapore study of adults seeking treatment, 41% had had acne since adolescence. Heat, humidity, sweat, masks and helmets add to it, and many adults, especially women in their twenties to forties, find breakouts persist.

This page is the starting point. It helps you judge how severe your acne is, explains which treatments fit which stage and what a facial can and cannot do, and points you to the detailed guide for your type of acne. Not every bumpy rash is acne, so the common look-alikes are covered too.

Severity

How to judge acne severity at home

Doctors grade acne by the type of spots and how much skin is involved. Singapore primary care guidance uses the Comprehensive Acne Severity Scale and adds that how severe the acne feels to you should also count. The self-check below, done in daylight on clean skin, is a guide to where to start, not a diagnosis.

• Mild: mostly blackheads and whiteheads (comedones), with a few small red bumps or pus spots and no deep lumps.
• Moderate: many red bumps and pustules on the face, chest or back, perhaps with an occasional deeper, tender lump.
• Severe: many deep, painful nodules or cysts, spots that merge, or acne spreading widely over the trunk.
• Scarring at any level: new dents, pits or raised scars mean the acne needs a doctor, even if the spots are few.
• Distress at any level: acne that affects your mood, work or social life is reason enough to see a doctor.
• Not sure it is acne: itchy, same-sized bumps, a rash around the mouth or bumps centred on hairs point to look-alikes, covered below.

Severity to treatment

Matching acne treatment to severity

The main guidelines agree closely. The 2024 American Academy of Dermatology guideline strongly recommends benzoyl peroxide, topical retinoids, topical antibiotics and oral doxycycline, and strongly recommends isotretinoin for acne that is severe, scarring, distressing or not responding to standard treatment. A South-East Asian consensus panel that included Singapore dermatologists matches treatments to severity in the same way, and warns against using topical antibiotics alone or together with oral antibiotics, to slow antibiotic resistance.

Over the counter

Over-the-counter acne treatments that work

For mild acne, pharmacy products can be enough if they are used steadily. Most need 8 to 12 weeks before you can judge them, because a new pore plug takes weeks to form and clear; switching products every fortnight is a common reason acne seems not to respond.

Start with one active at a time, at night, alongside a gentle cleanser, a light non-comedogenic moisturiser and daily sunscreen. Some dryness in the first weeks is normal; burning, swelling or a spreading rash is not, and needs a pharmacist's or doctor's advice.

• Benzoyl peroxide: kills acne bacteria, which are not known to become resistant to it, and helps unblock pores; 2.5% to 5% is usually enough, and it bleaches fabric.
• Salicylic acid: an oil-soluble exfoliant that works inside the pore; useful for blackheads and whiteheads.
• Azelaic acid at around 10% in skincare: calms inflammation and helps fade post-acne dark marks; the 20% cream is prescription-only.
• Niacinamide: a supportive ingredient for oiliness and redness, gentle enough to pair with other actives.
• Retinol: a cosmetic vitamin A ingredient, far gentler and slower than prescription retinoids and not a substitute for them in acne.

Prescription

Prescription acne treatments, by generic name

When acne is moderate or worse, scarring, or not improving after about three months of steady over-the-counter care, prescription treatment reaches the causes in ways skincare cannot. These are prescription-only medicines in Singapore. At IN Eternity Clinic, Dr Sin Yong prescribes them after a consultation when appropriate and reviews the plan at follow-up; SkinRev Lab does not prescribe or inject.

• Topical retinoids, such as adapalene and tretinoin: unblock pores and prevent new ones; the backbone of most plans and of maintenance.
• Combination gels, such as benzoyl peroxide with clindamycin or with adapalene: two mechanisms in one product.
• Oral antibiotics, such as doxycycline or erythromycin: a limited course, always with benzoyl peroxide or a retinoid, because antibiotic resistance in acne bacteria is growing in Singapore.
• Hormonal treatment for suitable women: the combined oral contraceptive pill or spironolactone, after checking for reasons not to use them.
• Isotretinoin: an oral retinoid for severe, nodular, scarring or stubborn acne, with strict pregnancy prevention and monitoring; many people have long remissions after a course.
• Cortisone (triamcinolone) injection: a tiny, diluted dose into a single large, painful cyst to settle it quickly; it does not stop new spots forming.

Acne facials

Acne facials and extraction at SkinRev Lab: what they can and cannot do

A facial cannot reduce oil gland activity, change hormones or reach deep inflammation, but it can clear congestion and calm irritated skin alongside your home routine or a doctor's treatment. In a small 12-week study of 20 adults with mild to moderate acne, six HydraFacial clarifying treatments two weeks apart, which included blue LED light, raised the share with clear or almost-clear skin from 20% to 65% on investigators' grading; there was no control group, so it is encouraging rather than proof.

At SkinRev Lab, a non-invasive aesthetic centre at CityLink Mall, the options for acne-prone skin are in the table, with prices before GST. For congestion, a HydraFacial every four to six weeks is a common rhythm. SkinRev Lab does not offer standalone chemical peels, LED facials or body acne sessions, and does not extract deep, painful or cystic spots. If you are taking isotretinoin, or stopped recently, exfoliating facials are usually postponed because the skin stays fragile for months; ask your doctor when it is safe.

Adult acne

Adult acne treatment: why acne persists after your teens

Acne is not only a teenage problem. Singapore primary care doctors note that blackheads and whiteheads are more typical in adolescents and cystic acne more typical in adults, and many adult women see breakouts along the jaw and chin that flare before a period. All acne is influenced by hormones; hormonal acne describes the cases where that influence is most visible.

Adult acne usually responds to the same first-line treatments as teenage acne, but adult skin can be more easily irritated by strong actives, so gentler strengths and a moisturiser matter more, and women may be offered hormonal treatment. Irregular periods, extra facial or body hair or scalp thinning alongside acne should be checked for polycystic ovary syndrome (PCOS).

For men, shaving, helmets and sports kit add friction and sweat, and acne on the chest and back is common. Pregnancy changes the rules: oral isotretinoin and topical retinoids are avoided, and any treatment should be agreed with your obstetrician.

Look-alikes and body acne

Not all breakouts are acne: look-alikes and body acne

Several common rashes look like acne but need different treatment, and acne products can make some of them worse. If your breakouts do not match the descriptions in the severity check, read the matching guide and consider a doctor's diagnosis before trying more acne products.

• Fungal acne (Malassezia folliculitis): itchy, same-sized small bumps on the forehead, chest and back, worse with heat and sweat; it needs antifungal treatment.
• Folliculitis: red bumps or pustules each centred on a hair, often after shaving, sweating or tight gym wear.
• Perioral dermatitis: small red bumps and flaking around the mouth and nose, often triggered by steroid creams; avoid extraction and peels during a flare.
• Back, chest and shoulder acne: common, often missed and sometimes mixed with fungal folliculitis; the trunk scars easily.
• Pimples on the buttocks: usually folliculitis or keratosis pilaris rather than true acne.
• Rosacea: flushing and redness with bumps but no blackheads; a separate condition with its own treatment.

See a doctor

When to see a GP or dermatologist about acne

A GP can start most prescription treatment and refer you on, and a dermatologist manages severe, stubborn or complicated acne. Singapore primary care guidance recommends dermatology referral for severe or stubborn acne, severe scarring, psychological distress, intolerance of first-line treatment, and suspected underlying disease. See a doctor if any of the following apply.

• Deep, painful lumps or cysts, or acne that is leaving dents, pits or raised scars.
• No clear improvement after about three months of steady over-the-counter care.
• Acne that starts suddenly in adulthood with irregular periods, extra hair growth or scalp thinning.
• Breakouts that began after a new medicine, such as steroid tablets or creams.
• Acne that affects your mood, sleep, work or social life.
• Sudden, severe, painful acne with fever or aching joints: seek medical care promptly.
• Itchy, uniform bumps, a rash around the mouth, or redness with flushing, which may not be acne at all.

Preventing scars

Preventing acne scars, and where to go in our network

The surest way to limit scars is to control acne early. In a study of 1,972 people consulting dermatologists, 43% had acne scars, 69% of those had only mild or moderate acne at the visit, and the time between acne starting and the first effective treatment was a key risk factor that can be changed. Do not squeeze deep spots, and see a doctor promptly for lumps that linger.

Red and brown marks after spots are not true scars and usually fade over months with sun protection and an end to picking. Dents and raised scars are structural; they are treated once active acne is under control, often with lasers, subcision or TCA CROSS. The guides below explain the difference and the options.

At IN Eternity Clinic, 9 Scotts Road, #12-01 Pacific Plaza, beside Orchard MRT, Dr Sin Yong grades acne, rules out look-alikes and prescribes treatment where suitable, then treats marks and scars as a separate step, priced at consultation; WhatsApp +65 8815 3008. SkinRev Lab, at #B1-28 CityLink Mall, linked underground to City Hall and Esplanade MRT, provides congestion and calming care and passes medical enquiries to the clinic; WhatsApp +65 8266 9585.
