Where they practise
- Clinic / practice: APAX Medical & Aesthetics Clinic — Woodlands (Junction 10) and Kovan/Hougang
Getting to the clinic
APAX Medical & Aesthetics Clinic operates in Woodlands at Junction 10 and in the Kovan/Hougang area. Junction 10 is a mall in the Woodlands area near Bukit Panjang and the wider north-west; it is served by buses along Woodlands Road and Bukit Timah Expressway access, with the mall’s own carpark for those driving, and Bukit Panjang MRT/LRT and Cashew MRT (DT) on the Downtown Line within the broader district. The Kovan/Hougang clinic is close to Kovan MRT (NE13) on the North-East Line, with Hougang MRT (NE14) nearby and bus services along Upper Serangoon Road; taxi and ride-hailing drop-off is straightforward, and there are HDB and mall carparks in the vicinity. When booking, check which branch your appointment is at, as the two locations are on different sides of the island and the journeys differ considerably.
What acne and scar treatment covers
Dr Ng’s stated focus is acne and acne scarring, alongside pigmentation disorders and laser surgery. Active acne management aims to reduce breakouts and inflammation using topical and oral treatments, in-clinic procedures and skincare adjustments, and to limit the formation of new scars. Acne scarring, once established, is addressed differently depending on the scar type: atrophic scars (such as ice-pick, rolling and boxcar scars) are commonly treated with fractional lasers, subcision, microneedling with radiofrequency, chemical reconstruction or fillers, while raised or pigmented marks need their own approaches. Pigmentation disorders such as post-inflammatory marks and melasma are managed with a combination of lasers, topical agents and strict sun protection. Because acne and its scarring usually develop over time and can recur, treatment is typically a staged, longer-term plan combining several modalities rather than a single procedure. Settling active acne first usually matters, because treating scars while breakouts continue tends to be less effective and risks fresh scarring. Setting realistic expectations about improvement, rather than complete removal, is an important part of scar treatment.
What to expect at a consultation
A first appointment usually begins with the history of your acne or scarring, previous treatments, current skincare, medications, allergies and any relevant medical conditions. The doctor examines the skin, often noting the scar types present and the degree of active acne, sometimes under magnified lighting. A plan is then discussed, frequently combining in-clinic procedures with home care and sun protection. Expect a clear account of how many sessions may be needed, the spacing between them, downtime such as redness or flaking, and possible side effects. For pigmentation, sun protection is emphasised, as ultraviolet exposure can undo progress and even darken some marks. Asking about the likely degree of improvement, the order in which problems will be tackled, and the alternatives is sensible before starting.
Booking, referrals and fees
The clinic can usually be approached directly without a referral. Acne and scar treatments for cosmetic purposes are generally elective and not subsidised; MediSave, MediShield Life and Integrated Shield Plans typically do not apply to cosmetic procedures, and consultations are usually paid out of pocket. Bring a list of medications, notes on past acne or scar treatments and any allergies. Since fees vary with the procedures and number of sessions, confirm the full cost and inclusions with the clinic before starting.
Common questions
Can acne scars be completely removed?
Most scar treatments aim for meaningful improvement rather than complete removal. The realistic degree of improvement depends on the scar type and is discussed after examination.
Should active acne be controlled before treating scars?
Generally yes. Settling active breakouts first helps prevent new scars and makes scar treatment more effective. The sequence is planned individually.
Why is sun protection emphasised?
Ultraviolet exposure worsens pigmentation and can undo progress, especially after lasers. Consistent sun protection is usually part of acne, scar and pigmentation plans.
Acne scar types explained
Acne scarring, a central focus of Dr Moses Ng’s practice at APAX Medical & Aesthetics Clinic, is not a single problem but several, and the treatment depends heavily on the type. Atrophic scars, the most common, are indentations left after the skin heals, and they are usually grouped into three patterns: ice-pick scars, which are narrow and deep; boxcar scars, which have wider, sharper edges; and rolling scars, which give the skin a gently undulating surface. Each tends to respond best to particular approaches, such as fractional lasers, subcision, microneedling with radiofrequency, chemical reconstruction or fillers, and a realistic plan often combines more than one. Raised scars and lingering pigmented marks behave differently again and need their own management.
Sequencing matters as much as the choice of procedure. Active acne is usually settled first, because treating scars while breakouts continue tends to be less effective and risks fresh scarring. Pigmentation, including post-inflammatory marks and melasma, is managed alongside with lasers, topical agents and strict sun protection, since ultraviolet exposure can darken marks and undo progress. Throughout, the goal is meaningful improvement rather than complete removal, set realistically after examining the skin.
How to prepare and tips for your visit
- Bring a list of your medications, notes on past acne or scar treatments, and details of any allergies.
- Attend without make-up where possible, so the doctor can examine the scar types and any active acne clearly.
- Note how your skin has responded to previous products or procedures, including anything that irritated it.
- Ask about the likely number and spacing of sessions and the downtime, such as redness or flaking, so you can plan around social or work commitments.
- Be ready to commit to sun protection and a home regimen, as these strongly affect results, particularly for pigmentation.
- Confirm which branch your appointment is at, as the clinic operates in the Woodlands and Kovan/Hougang areas on different sides of the island.
More questions
How many sessions will scar treatment take?
This depends on the scar types present and how your skin responds. Scar treatment is usually a staged, longer-term plan combining several approaches rather than a single procedure, and the likely schedule is discussed after examination.
Are acne and scar treatments covered by MediSave or insurance?
Treatments for cosmetic purposes are generally elective and not subsidised; MediSave, MediShield Life and Integrated Shield Plans typically do not apply to cosmetic procedures, and consultations are usually paid out of pocket. Confirm the full cost and inclusions with the clinic before starting.
