Comedonal Acne (Mild)
Blackheads and whiteheads without inflammation. While it doesn’t scar, unmanaged comedonal acne frequently progresses to inflammatory forms. Treatment focuses on regulating sebum and preventing pore blockage.

Acne vulgaris is a chronic inflammatory skin condition affecting the pilosebaceous unit: the hair follicle and its attached oil (sebaceous) gland. When excess sebum, dead skin cells, and bacteria accumulate within a follicle, the result is the spectrum of lesions we know as acne: from surface-level blackheads and whiteheads, through to red papules, pus-filled pustules, and deep, painful cystic nodules.
In Singapore, acne affects up to 85% of people aged 12–25 at some point, and adult acne (particularly in women) remains a common and undertreated concern well into the 30s and 40s. Singapore’s year-round heat and humidity amplify sebum production and create an environment where acne-causing bacteria thrive on the skin surface.
Androgen hormones, particularly during puberty, the menstrual cycle, or periods of high stress, stimulate sebaceous glands to overproduce oil. In Singapore’s humid climate, excess sebum sits on the skin surface and mixes with environmental pollutants, creating ideal conditions for pore blockage.
Excess sebum traps dead skin cells inside the follicle. If the pore opening remains closed, a whitehead (closed comedone) form. If it stays open, oxidation turns the trapped material dark; this is a blackhead (open comedone). Neither type causes scarring at this stage.
The blocked follicle becomes an oxygen-depleted environment where Cutibacterium acnes (C. acnes) bacteria multiply rapidly. This bacterial overgrowth triggers the immune system’s inflammatory response.
The immune response produces the visible signs of inflammatory acne: red papules, painful pustules, and, in severe cases, deep, fluctuant cysts and nodules. It is at this stage that dermal collagen damage and permanent scarring become a real risk without medical intervention.
Not all acne looks or behaves the same way. Critically, not all acne is treated the same way. Dr Wong diagnoses and manages the full spectrum of acne presentations:
Blackheads and whiteheads without inflammation. While it doesn’t scar, unmanaged comedonal acne frequently progresses to inflammatory forms. Treatment focuses on regulating sebum and preventing pore blockage.
Red papules and pus-filled pustules due to bacterial proliferation within comedonal acne. It has high PIH risk in Asian skin if managed incorrectly. However, these types of lesions often respond well to prescription topicals and light-based treatments.
Deep, painful cysts and nodules extending into the dermis. Dr Wong manages this with oral isotretinoin, antibiotics, or intralesional corticosteroid injections alongside acne blue light or laser therapy.
Cyclical breakouts along the chin and jawline, often linked to menstrual cycles, PCOS, or hormonal transitions. Frequently resistant to standard topicals without addressing the underlying trigger. Dr Wong assesses hormonal root causes and coordinates with a gynaecologist or endocrinologist where needed.
Ranges from mild comedonal breakouts to severe nodulo-cystic acne. Early intervention matters: the psychological impact on self-esteem during adolescence is clinically significant.
Influenced by sweat, friction and Singapore’s humidity. Thicker truncal skin requires different treatment protocols. Dr Wong prescribes both topical and oral therapies where indicated.
Frequently misdiagnosed as bacterial acne. Presents as small, uniform, itchy papules that don’t respond to standard acne treatments. Some antibiotics can worsen it. Dr Wong often corrected misdiagnosed acne with prescribes antifungal therapy.
PIH (red or brown marks post-breakout) is common in Asian skin and can persist for months without treatment. True acne scars, such as ice pick, boxcar, rolling, or keloidal, require dedicated scar revision. Dr Wong addresses both.
The primary driver across all ages. Androgens stimulate sebaceous glands to enlarge and produce more sebum. Puberty, menstrual cycles, pregnancy and PCOS, are all common triggers.
Year-round heat and humidity increase sweat and sebum production, promote bacterial proliferation on the skin surface, and cause follicular swelling that traps dead skin cells more readily.
Elevated cortisol levels from work, academic, or lifestyle stress stimulate androgen production, triggering or worsening breakouts. Stress also impairs skin barrier function and delays wound healing.
Heavy moisturisers, occlusive sunscreens, and pore-blocking makeup worsen acne.
Popping, squeezing, or picking lesions pushes bacteria deeper, worsens inflammation, and significantly increases the risk of permanent scarring; this is one of the most common reasons patients come to Dr Wong after months of self-treatment.
A family history of severe acne significantly increases your own risk of developing cystic or nodular acne that requires specialist management.

Most people attempt to manage acne with over-the-counter products, facial treatments, or general prescriptions before seeking specialist care. The problem: by the time they see Dr Wong, many have already developed scarring or PIH that could have been prevented with earlier specialist intervention.

Dr Wong creates every treatment plan around the patient’s specific acne type, severity, skin tone, and lifestyle. The following treatments are available individually or in combination:
This is first-line treatment for mild to moderate acne. Topical prescriptions from Dr Wong work at the follicular level, targeting the four drivers of acne simultaneously. Commonly used topical medicines include Tretinoin (Retinoids), topical antibiotics (Clindamycin, Erythromycin), Benzoyl Peroxide (often combined with topical antibiotics), Azelaic Acid and Clascoterone.
For moderate to severe inflammatory acne, oral medications work systemically to address the biological drivers that topical therapies cannot reach. Common ones include oral antibiotics (Doxycycline, Azithromycin); Oral Contraceptives (for women) and Spironolactone (an anti-androgen medication) and Isotretinoin (Oral).
This is a soft acne laser peel to remove dead skin cells and deeply cleanse the pores to control outbreaks. In addition to controlling the outbreak, the heat generated from the laser also improves the skin pores and rejuvenates the skin.
M22 OPT Blue Light delivers a powerful and targeted blue light beam to kill the bacteria in the acne. It is especially ideal for pregnant ladies, patients with multiple antibiotic allergies, and patients with sensitive facial skin intolerant to topical medications.
A quick injection directly into a painful cyst or nodule that reduces swelling and shrinks the lesion within 24–48 hours. It also significantly lowers the risk of scarring from that spot.
A gentle laser treatment designed specifically for Asian skin tones to safely fade the red and brown marks left behind by acne. It targets pigmentation without triggering further skin darkening.
Medical-grade peels exfoliate the skin, clear blocked pores, and speed up the fading of post-acne marks. Modified TCA peels are especially effective for acne-prone skin as they penetrate deep into pores to dissolve oil and debris.

Dr Wong is an accredited Dermatologist with 30 years of specialist experience. Many acne patients have benefited from his vast experience and sound experience to treat all kinds of acne.
Not every breakout is acne. Dr Wong identifies the exact condition by distinguishing acne vulgaris from rosacea, fungal folliculitis, perioral dermatitis, and other acne mimics that require different treatments entirely.
Asian skin is uniquely susceptible to PIH from incorrect laser settings or over-aggressive treatment. All protocols at Assurance Skin are calibrated specifically for our local patient population.
We treat active acne and its consequences, PIH and scarring, concurrently following proper international guidelines. Prescription medications and laser technology are used together, not as separate courses.
All medical laser and light-based devices at Assurance Skin are fully HSA-registered and FDA-cleared. Patients can be confident in the safety profile and clinical evidence base for every device used.

Note: Acne treatments are generally not claimable under personal or corporate insurance (with some exception). Dr Wong provides full, transparent pricing during your consultation. You can consider carefully before taking up the treatment.
A dermatologist provides a medical diagnosis by identifying whether you have acne vulgaris or a condition that mimics it and can prescribe treatments unavailable over the counter. Personnel at Facial spas or beauty salons are not trained to diagnose medical conditions and they cannot prescribe medications.
Several conditions are commonly mistaken for acne and require entirely different treatments, including rosacea, fungal folliculitis, perioral dermatitis, and hidradenitis suppurativa. Getting the diagnosis right before treating is the most important first step.
A temporary purging phase is possible when starting prescription retinoids (typically lasting 2–4 weeks) as deeper-seated comedones surface more quickly than usual. This is an expected part of the process, not a sign that treatment is failing.
Yes; the same treatments are available to both age groups but are prescribed differently based on the underlying cause.
Yes, treating active acne and early scarring concurrently is often the most efficient approach. More intensive scar revision procedures are typically introduced once active acne is well controlled, usually around 2–3 months into treatment.
Acne recurs when the underlying trigger is not fully addressed or when maintenance is not sustained; common reasons include untreated hormonal drivers, discontinuing topical retinoids too soon, or continued use of comedogenic products. A consultation can help identify the root cause of recurrence rather than treating symptoms alone.
Isotretinoin is a clinically well-established option when prescribed by a qualified specialist with appropriate monitoring, and is indicated for severe or scarring acne that has not responded to other treatments. Side effects are real and require management, including mandatory blood tests and, for women of childbearing potential, strict contraceptive requirements due to teratogenic risk.
Over-the-counter products work at the skin surface and are appropriate for mild, early-stage acne, whilst prescription topicals penetrate deeper and address the biological drivers of acne at the follicular level. Prescription treatment is based on a clinical assessment of your specific condition, not a generic product selection.
Acne treatments are generally not claimable under private or corporate insurance (with some exception). Full, itemised pricing is provided during your consultation.
Acne is a medical condition, not a hygiene problem, and not something you simply have to live with. With accurate diagnosis, the right prescription treatment, and specialist oversight from Dr Wong Soon Tee, most acne cases (including severe cystic and hormonal acne) can be effectively managed.
