Light for the inflammation. Medicine for the cause.

Lasers can calm inflamed acne, reduce oiliness for a time and fade the marks acne leaves. At IN Eternity Clinic on Orchard Road, Dr Sin Yong uses them alongside medical treatment, not instead of it.

Key facts

What lasers act on: inflammation around the follicle, oil-gland activity for a period, and the red or brown marks acne leaves. They do not stop follicles blocking or change hormonal drive.
675 nm, Shaonu Guang (少女光): a fractional 675 nm laser on the DEKA RedTouch Pro, working at the reticular dermis with contact cooling; used for inflammatory acne, redness and pores.
Nd:YAG and carbon laser peel: 1064 nm energy, as used in R2 Glow on the Fotona StarWalker or a carbon laser peel, warms the upper skin and oil glands and clears surface oil.
Marks after acne: brown post-inflammatory pigmentation is treated with picosecond T2 Frax Radiance on DEKA TORO once breakouts are controlled; red marks often respond to 675 nm.
Not a laser problem: deep nodular or scarring acne needs prescription treatment promptly; laser is added as support, not as the main treatment.

How it works

What can a laser actually do for acne?

Acne has four drivers acting together: follicles that block with sticky skin cells, oil glands that produce more sebum under the influence of androgens, overgrowth of Cutibacterium acnes in the blocked follicle, and the inflammation that follows. Lasers and light act mainly on the last of these, and to a lesser degree on oil. Heat delivered into the dermis calms inflammation, and some wavelengths warm the oil glands enough to reduce oiliness for a period.

That is useful, but it is not the whole picture. No laser stops follicles from blocking or changes how oil glands respond to hormones, so a plan built on laser alone tends to give a partial, temporary result. Published reviews describe the evidence for lasers in active acne as encouraging but variable, with better results when light is combined with standard medical treatment. That is how it is used at IN Eternity Clinic: medical management first, with laser added where it contributes. See acne treatment for the medical side.

Other light-based acne treatments exist, including blue light, photodynamic therapy with a light-sensitising cream, and newer lasers designed to target oil glands. This page explains what is used at IN Eternity Clinic; at assessment, Dr Sin Yong will tell you which option he recommends and why, including when a light treatment is not needed at all.

At IN Eternity Clinic

Which laser for which kind of acne?

The choice follows what the skin shows on the day:

What you see	Laser used	What it does
Red, inflamed spots and background redness	Shaonu Guang (少女光) 675 nm	Calms inflammation and redness in the dermis under contact cooling
Oily, congested skin with small spots	Carbon laser peel or R2 Glow	Clears surface oil and warms oil glands for a period
Brown marks after spots settle	T2 Frax Radiance on DEKA TORO	Breaks up pigment with little heat
Indented scars	Acne scar laser pathway	Remodels scar tissue once acne is controlled

Many plans combine a laser with a medicated skincare routine, and with a Hydrafacial or salicylic acid peel for blackheads and whiteheads. Deep, painful nodules are never squeezed, because that pushes inflammation further into the skin.

Comfort

Does it hurt? Comfort and numbing

Most acne laser sessions are well tolerated. The 675 nm laser feels like warmth and light prickling, eased by the contact cooling built into the treatment. Nd:YAG passes and the carbon laser peel feel like quick snapping on the skin, with a faint crackle as the carbon is cleared. Picosecond treatment for marks feels like sharper, brief snaps.

Many people need no numbing. Numbing cream can be applied for 20 to 30 minutes beforehand if your skin is sensitive or inflamed spots are tender. Protective eyewear is worn throughout. Afterwards the skin feels warm, like mild sunburn, for an hour or two.

Timeline

What to expect: day by day

Day 0. Assessment and standard photographs, then the laser if the skin is ready. Mild redness and warmth for a few hours; inflamed spots may look a little redder at first. Gentle cleanser, moisturiser and sunscreen.

Days 1–3. Redness settles. Skin may feel slightly dry. Brown marks treated with picosecond laser can look darker before they flake.

Week 1. Inflamed spots tend to flatten sooner. New spots can still appear, because the underlying drivers are being treated more slowly by your skincare or medicine.

Weeks 2–4. Sessions are usually repeated every two to four weeks as a short course, alongside your daily routine.

Review at about eight to twelve weeks. This is a fair point to judge the combined plan. Lasers are tapered or stopped once acne is controlled, and marks or scars are planned next.

Suitability

Who is laser acne treatment for, and who should wait?

It suits people with mild to moderate inflammatory acne or oily, congested skin who want faster calming alongside medical treatment, people who cannot tolerate some topical treatments well, and anyone left with red or brown marks once breakouts settle. It can also help reduce how much medicine is needed for maintenance in some people.

Some situations need a different first step. Deep nodular or cystic acne needs prescription treatment promptly; see cystic acne treatment. Uniform, itchy bumps may be fungal acne, which needs antifungal treatment. Recent sun tanning, photosensitising medicines, pregnancy and an active cold sore are reasons to wait. During oral isotretinoin, a prescription medicine, some gentle lasers may be considered with care; see isotretinoin and procedures.

Myths and facts

Common myths, answered

Myth: A laser can cure acne.
Fact: Lasers calm inflammation and oil for a period. They do not stop follicles blocking or change hormonal drive, so they work alongside medical treatment.
Myth: Laser acne treatment means a long recovery.
Fact: The lasers used for active acne are non-ablative. Most people have mild redness for a few hours and return to their day.
Myth: Lasers are unsafe for Asian skin.
Fact: Pigment risk is real, which is why wavelengths and settings are chosen for Fitzpatrick III to V skin and sun protection is part of the plan.
Myth: If one laser session helps, more sessions closer together help faster.
Fact: Skin needs time to settle between sessions. Treating too often adds heat and irritation, which can worsen marks.

Questions

Frequently asked questions

Can laser treatment cure acne?

No. Lasers act mainly on inflammation and, for a period, on oiliness. They do not change follicle blockage or how oil glands respond to hormones, which is why acne usually returns if laser is used alone. Used alongside skincare or prescription medicine, laser can help acne settle faster and fade the marks it leaves.

How many laser sessions are needed for acne?

A short course is usual, often four to six sessions spaced two to four weeks apart, adjusted to how your skin responds. Once breakouts are controlled, sessions are reduced or stopped and the focus moves to maintenance and to any marks or scars. Dr Sin Yong reviews progress against your first photographs.

Can I have laser while taking acne medicine?

Often, yes, with adjustments. Topical retinoids may be paused for a few days around a session. During oral isotretinoin, a prescription medicine, gentle non-ablative lasers may be considered with care according to 2017 consensus guidance, while aggressive resurfacing is avoided. Your prescribing doctor should know about any procedure planned.

Is laser acne treatment safe for darker or Asian skin?

It can be, with appropriate settings. Asian skin is more prone to post-inflammatory pigmentation after heat or irritation, so wavelengths, energy and cooling are chosen for your skin type, and daily sunscreen is essential. Tell the clinic about recent tanning or any history of dark marks after previous treatments.

Is a laser better than a facial for acne?

They do different jobs. A facial or Hydrafacial clears blackheads, whiteheads and surface oil. A laser calms inflammation in the dermis and fades marks. Neither replaces medical treatment of the causes of acne. Many plans use both at different times, chosen by what the skin needs.

How much does laser acne treatment cost in Singapore?

Cost depends on which laser suits your skin, the number of sessions, whether marks are treated as well as active acne, and what medical treatment is needed alongside. A short course is planned differently from maintenance. The plan and its cost are explained after assessment, and the consultation fee is waived with any medical treatment.
