Laser hair removal in Singapore uses laser energy absorbed by melanin in the hair to heat the follicle and reduce regrowth. Because skin pigment competes for the same energy, the wavelength has to match the skin: 755 nm alexandrite for lighter skin, 1064 nm Nd:YAG for darker skin. Treatment is staged, doctor-supervised and planned after assessment.

Also called: medical laser hair removal, 激光脱毛, 医療レーザー脱毛

Key takeaways
  • Laser hair removal uses laser energy absorbed by melanin in the hair to heat the follicle and reduce regrowth.
  • The wavelength must match the skin: 755 nm alexandrite for lighter skin, 1064 nm Nd:YAG for darker skin.
  • White, grey or very fine hair carries little melanin and responds poorly, whatever the device.
  • Treatment is staged across visits, because follicles respond mainly in the active growth phase.
  • Every session is doctor-supervised, with settings determined by Dr Sin Yong after examining skin and hair.

In brief

Laser hair removal in Singapore uses laser light absorbed by the pigment in each hair to heat the follicle and reduce regrowth. Dr Sin Yong works on a dual-wavelength platform, 755 nm alexandrite and 1064 nm Nd:YAG, so the setting follows your skin tone. IPL and SHR offers are different technologies sold under a similar name.

QuestionLaser hair removal
Who it suitsHair that carries enough pigment to respond, on skin that is not freshly tanned. White, grey or very fine hair carries too little pigment for any laser to target.
What is assessed firstDr Sin Yong examines the skin and the hair in each area. New or rapidly increasing hair in a woman is assessed for a hormonal cause first, dark or changing moles in the field are checked, and earlier IPL or diode treatment is taken into account.
How it is doneOn the R2 Glow platform, a long-pulsed laser carrying 755 nm alexandrite and 1064 nm Nd:YAG. The wavelength is chosen area by area, with epidermal cooling, and you shave rather than wax beforehand.
Who should waitRecently tanned, sunburnt or self-tanned skin; pregnancy; active infection, cold sore, folliculitis or eczema in the area; recent isotretinoin, until discussed.

How Laser Hair Reduction Works

Laser hair removal suits hair that carries enough pigment to respond, on skin that is not freshly tanned. Dr Sin Yong examines the skin and the hair in each area and chooses the wavelength area by area. The reason is the principle behind it, selective photothermolysis. Melanin, the pigment in the hair shaft, absorbs laser energy. That energy turns into heat. The heat then spreads to the parts of the follicle that produce the hair.

Two things follow from this. First, the target is pigment — so hair that carries little melanin responds poorly regardless of the device. Second, the melanin in your skin competes for the same energy, which is where skin type becomes the governing variable.

Hair also grows in cycles, and only follicles in the active anagen phase are susceptible at any given moment. This is why treatment is staged rather than done once.

Hair growth cycle: why only anagen follicles respond to laser Three hair follicles in a skin cross-section. Anagen, the growing phase: a long follicle reaching into the fat with a pigmented bulb attached to its papilla; melanin in the hair absorbs the laser energy and the heat spreads to the parts of the follicle that make the hair, so this is the laser target. Catagen, the regressing phase: the follicle shrinks upwards and the bulb loses its pigment. Telogen, the resting phase: a short follicle holding a club hair with no pigmented bulb. The cycle then repeats. Follicles are at different stages at any one time, so treatment is staged.

Which Hair Removal Laser: Why the Wavelength Has to Match the Skin

This is the part most often glossed over, and it is the whole reason a dual-wavelength platform exists.

755 nm alexandrite is strongly absorbed by melanin. Where there is good contrast between dark hair and lighter skin — Fitzpatrick I to III — that strong absorption is precisely what you want. But the same property becomes a liability as skin pigment increases: surface melanin absorbs energy intended for the follicle.

1064 nm Nd:YAG behaves differently. The longer wavelength is less readily absorbed by melanin in the upper layers and penetrates deeper, so more energy reaches the follicle rather than being taken up on the way through. This is what makes it the appropriate wavelength for Fitzpatrick IV to VI.

Neither wavelength is better. They answer different skin: a 2020 systematic review and meta-analysis of 12 comparative trials in skin types III to VI found long-pulsed 1064 nm Nd:YAG carried less risk of post-inflammatory hyperpigmentation than IPL. Having both on one platform means the treatment is matched to you, rather than you being told your skin type is unsuitable. How the 1064 nm wavelength is used on darker skin is set out in laser hair removal for dark skin, and how the three laser types differ in diode vs alexandrite vs Nd:YAG.

Laser hair removal compared with IPL, waxing, threading and electrolysis

Laser hair removal in Singapore sits beside several other ways of removing unwanted hair, and they differ in whether they act on the follicle or only on the hair above it. The comparison sets out how each works and who it tends to suit; only medical-grade laser is offered here.

MethodHow it worksWho it tends to suitDowntime and skin factorsMain risksOffered here?
Laser: 755 nm alexandrite or 1064 nm Nd:YAGOne wavelength absorbed by hair pigment heats the follicle to reduce regrowth, in staged visitsPigmented hair; 1064 nm for darker skin tonesRedness and swelling around follicles; sun and tanning avoidedBurns, pigment change, and rarely paradoxical extra hair growthYes, performed by Dr Sin Yong
IPL (intense pulsed light)A filtered flash lamp emitting a broad band of lightLighter skin with dark hairAs for laserMore energy absorbed by skin pigment, so a higher risk of darkening in darker skinNot used for hair removal here
Home IPL devicesA lower-energy flash lamp used at homeLighter skin with dark hairSelf-managedEye exposure; burns on tanned or darker skinNot applicable
Waxing and sugaringPulls hair out from the rootAny hair colourRedness and bumps; regrowth as the hair cycle continuesIngrown hairs, folliculitis and darkening in the bikini and underarmNo; laser hair removal used instead
Threading and pluckingRemoves individual hairs from the rootSmall areas such as the brows and upper lipBrief rednessIngrown hairs and irritationNo; laser hair removal used instead
Shaving and hair removal creamsRemove hair at or just below the surfaceAny hair and skinNone, but frequent repetitionRazor bumps; irritation from creamsNot applicable
ElectrolysisA fine probe passes a current into each follicle, one at a timeWhite, grey, blond or fine hair that laser cannot targetSlow; redness at treated folliclesScarring or pigment change if poorly performedBy referral

For most people with pigmented hair, the choice is between a staged laser plan and ongoing temporary methods, and electrolysis remains the option for hair with too little pigment for any laser. Waxing, plucking and threading are stopped before and during a laser plan, because they remove the root the laser needs. IPL and laser are compared in more detail on IPL vs laser hair removal, and planning for darker skin is on laser hair removal for dark skin.

Does laser hair removal work? What published studies show

An evidence-based review of 9 randomised and 21 controlled trials concluded that lasers reduce hair for up to six months after treatment, that repeated treatments improve the effect, and that lasers outperform shaving, waxing and electrolysis. It found evidence of longer-term reduction for alexandrite and diode lasers, and probably for Nd:YAG lasers, and no evidence that any system removes hair completely and for good.

A 2022 systematic review of five randomised trials with 223 patients reported average long-term hair reduction of 35% to 84% for alexandrite, 32.5% to 69% for diode and 30% to 74% for Nd:YAG lasers. Reduction was greatest on the legs and lowest on the face. The accurate description is therefore long-term hair reduction, with the result depending on the body area, the hair and the skin type.

What This Means in Singapore

Singapore's population spans a wide phototype range, and a great deal of it sits in Fitzpatrick III to V — exactly the range where wavelength choice stops being academic.

Treatment on darker skin with an inappropriate wavelength or setting risks epidermal injury and post-inflammatory pigment change. Getting this right is a matter of assessment and parameter selection, not of buying a machine.

The same platform underpins Dr Sin Yong's R2 Glow protocol, where long-pulsed delivery is directed at inflammatory activity in the skin rather than at the hair follicle.

Areas Treated

Areas are planned together where that makes sense — a brazilian, underarms and legs are commonly assessed in the same consultation — but each is set independently, because the skin and the hair differ from one area to the next. Each area has its own guide: underarm laser hair removal, brazilian laser hair removal, leg laser hair removal, facial laser hair removal and laser hair removal for men.

Brazilian & bikiniCoarse, dark hair on skin that is often a shade deeper than the face — wavelength and cooling matter most here.
UnderarmsOne of the commonest requests, often together with pigment and sweat in the same area.
Full legsThe largest area and the one most often started abroad; previous treatment is taken into account when settings are chosen.
ArmsFiner hair in many patients, where the alexandrite wavelength is often the better match on lighter skin.
Upper lip & chinFine or hormonal hair close to the mouth, assessed for cause as well as treated.
Back, chest & beard lineDense terminal hair and, in men, the ingrown-hair pattern that comes with shaving.

Brazilian and bikini laser hair removal

The bikini line and the brazilian area carry coarse, dark hair on skin that is often a shade deeper than the face, and thinner and more sensitive than the skin of the legs. That combination is why the laser setting matters most here.

The hair removal laser used is the Clarity II by Lutronic, which carries two wavelengths in one machine: 755 nm alexandrite and 1064 nm Nd:YAG. Skin colour decides which is used. The 755 nm alexandrite suits lighter skin, where dark hair stands out against it; the 1064 nm Nd:YAG is less absorbed by the pigment at the skin's surface and reaches deeper, so it is the choice for darker or recently tanned skin. Coarse and finer hair often sit side by side in the same area, and the settings are adjusted for each.

Dr Sin Yong performs the treatment himself. He holds a diploma in obstetrics and gynaecology, and examines the area as a doctor before the laser is set: ingrown hairs, folliculitis, pigment change, moles within the treatment field and any skin condition are noted first. If you would prefer a female doctor, one is available on request.

Every brazilian or bikini treatment starts with an assessment of the skin and the hair. The area is shaved beforehand, not waxed or plucked, so the hair shaft stays in the follicle.

How Dr Sin Yong approaches laser hair removal

Laser hair removal here runs on the R2 Glow platform. It is a long-pulsed laser that carries both 755 nm alexandrite and 1064 nm Nd:YAG. Dr Sin Yong examines the skin and the hair in each area at the clinic on Orchard Road, Singapore. He chooses the wavelength area by area, rather than once for the whole body. He uses 755 nm where finer or lighter hair sits on lighter skin, and 1064 nm where the skin is darker or recently tanned. In naturally darker zones such as the underarm and bikini line, he uses conservative settings and pays close attention to cooling.

Areas treated together, such as a brazilian, underarms and legs, are still set independently. Previous IPL or diode treatment elsewhere is taken into account when settings are chosen, patients shave rather than wax beforehand so the hair shaft stays in the follicle, and every session is doctor-supervised rather than run from a fixed protocol.

How Dr Sin Yong does it

  1. He examines the skin and the hair in each area, and checks new medication, recent isotretinoin and any previous IPL or diode treatment.
  2. The area is shaved, not waxed or plucked, beforehand so the hair shaft stays in the follicle.
  3. He chooses the wavelength area by area: 755 nm alexandrite for finer or lighter hair on lighter skin, 1064 nm Nd:YAG for darker or recently tanned skin.
  4. Each area is set independently, with conservative settings and close attention to cooling in naturally darker zones such as the underarm and bikini line.
  5. Every session is supervised by him rather than run from a fixed protocol.

Is laser hair removal safe? The risks to know

Laser hair removal has a well-described risk profile, and most effects are short-lived: redness, small raised bumps around the follicles, mild swelling and a sunburn-like warmth that settle on their own. Less commonly the skin can blister, crust or burn, and the healed area can turn darker or lighter than the skin around it. A review of published adverse effects found pigment change in up to 19% of patients treated with shorter-wavelength lasers, particularly in darker skin, compared with 2–3% with the 1064 nm Nd:YAG.

Rarer effects include paradoxical hypertrichosis, folliculitis, a flare of cold sores on the upper lip and whitening of hairs. Eye injury is a recognised hazard of any hair-removal laser, which is why protective eyewear is worn throughout and treatment stays outside the orbital rim.

These risks are reduced by matching the wavelength to skin type, epidermal cooling, conservative settings in naturally darker areas, avoiding a tan, and reviewing the skin as treatment progresses. What the first days look like is described in laser hair removal downtime.

Who it suits, who should wait, who is referred on

Tends to suit

  • Hair that carries enough pigment to respond
  • Skin that is not freshly tanned, so energy reaches the follicle
  • Wanting a doctor-supervised plan matched to skin type
  • Areas such as the beard line, where ingrown hairs are a concern, assessed individually

Better to wait

  • Recently tanned, sunburnt or self-tanned skin
  • Pregnancy, or active infection, cold sore, folliculitis or eczema in the area
  • Recent isotretinoin, until discussed

Referred on

  • New or rapidly increasing hair in a woman: assessed for a hormonal cause first
  • Dark or changing moles in the field: skin check before any treatment
Who should not have this treatment
  • Pregnancy (treatment deferred)
  • Active infection, cold sore, inflamed folliculitis, eczema or broken skin in the area
  • Photosensitising medicines or recent isotretinoin (discussed before any pulse)
  • Vitiligo, or pigment change after previous laser or IPL (caution advised)
  • Tattoos, cosmetic tattooing or dark moles in the treatment field
  • Recently tanned or sunburnt skin

People with white, grey or very fine hair, or with freshly tanned skin, tend to respond poorly, as laser targets pigment and this is the wrong tool for them. Who should wait, and why, is covered in laser hair removal suitability, and why there is no fixed number of visits in how many laser hair removal sessions.

Before you book

Questions to ask before laser hair removal in Singapore

These questions help you compare offers by what is actually being done rather than by the name.

  • Who assesses my skin and hair, and who performs or supervises the treatment?
  • Is the device a laser or IPL, which wavelength would be used for my skin type, and why?
  • What can it not do for fine, light or grey hair?
  • What are the risks for my skin tone, including burns and pigment change?
  • What aftercare is advised, and how do I reach the clinic if a reaction appears?
  • Which alternatives were considered for my hair and skin?

Myths we hear in clinic

“IPL and laser hair removal are the same thing.”

IPL emits broad-spectrum light, while a laser emits a single wavelength matched to melanin in the follicle. Shaving, waxing and home devices are compared with clinic treatment in home IPL vs clinic laser hair removal.

“Darker skin cannot have laser hair removal.”

The 1064 nm Nd:YAG wavelength is chosen for darker skin after assessment, with settings set for that skin.

What decides the fee for laser hair removal in Singapore

Three things shape the fee more than any other: the area, the density of the hair and the device and wavelength used. Area matters because a small zone such as the upper lip differs from the legs, and several areas planned together differ from one. Hair density and thickness matter because they affect how the plan is set for each region, and dense coarse hair is planned differently from fine hair. The device and wavelength, and the consumables involved, are part of the cost, which is one reason a price list that names only an acronym is hard to compare with a doctor-supervised plan.

Other factors are the number of passes or zones, whether treatment started elsewhere changes the plan and whether areas are combined. Fees are not published on this site. A written quote is given at consultation, after Dr Sin Yong has examined the skin and hair in each area, and the consultation also decides whether treatment is advised at all. White, grey or very fine hair may not suit laser, and it is better to learn that at the consultation than after a course has started. If the assessment finds that another method or no treatment suits you better, that is what will be said, and nothing is agreed before you have heard it.

What it is not

  • Not IPL, SHR or diode under another name: this is a long-pulsed 755 nm alexandrite and 1064 nm Nd:YAG laser platform.
  • Not one wavelength for all: 755 nm suits lighter skin, 1064 nm darker skin, chosen after examination.
  • Not for white, grey or very fine hair, which carries too little melanin to respond to any device.

Laser hair removal Singapore in one minute

Laser hair removal in Singapore heats the pigment in each hair to reduce regrowth; it does not remove every hair for good. Dr Sin Yong examines the skin and hair in each area and chooses 755 nm alexandrite or 1064 nm Nd:YAG area by area, because skin pigment competes with hair pigment for the energy. White, grey or very fine hair responds poorly. Treatment is staged, tanned skin waits, and the fee depends on the area, hair density and device, set out in writing after assessment.

Frequently Asked Questions

Yes, usually. Shaving the area beforehand, as instructed, leaves the root and its pigment in the follicle for the laser to target while removing the hair above the skin, which would otherwise absorb energy at the surface and can singe. Do not wax, pluck or thread before treatment, because those remove the root the laser needs. When to shave is explained when you book, and the skin should be free of fresh cuts or irritation.
No. Waxing, plucking, threading and epilating pull out the root, which is what the laser targets, so they are avoided between visits and before treatment. Shaving and trimming are fine, because they leave the follicle and its pigment in place. If ingrown hairs or folliculitis are a problem, mention them at the review, because they are settled before the next treatment.
Laser hair removal is usually postponed during pregnancy. There is no evidence that the laser itself harms a pregnancy, but the evidence in pregnancy is limited, hormonal changes can bring new hair growth that later settles, and skin is more prone to pigment change while pregnant. Treatment is normally planned for after the pregnancy. Tell the doctor if you are pregnant, trying to conceive or breastfeeding.
It can reduce coarse facial and body hair in polycystic ovary syndrome as long as the hair is pigmented, but the hormonal driver keeps producing new hair, so maintenance is usually needed and results vary. Laser is usually planned alongside medical management of PCOS by your own doctor or gynaecologist. Darker hair tends to respond more readily than fine or light hair, and the wavelength is chosen for your skin tone at assessment.
No. Diode laser hair removal in Singapore usually uses a single fixed wavelength of 808 or 810 nm, often in quick in-motion passes. Dr Sin Yong uses R2 Glow, a long-pulsed platform carrying both 755 nm alexandrite and 1064 nm Nd:YAG with epidermal cooling, and chooses the wavelength area by area. A diode can treat many skin types; on darker skin it relies on lowering the fluence alone.
Ask which laser or light device will be used, then check it on the Health Sciences Authority (HSA) medical device register. In Singapore, medical devices, which include most aesthetic lasers, must be registered with HSA before they can be supplied; only the lowest-risk Class A devices are exempt. Ask too whether the device is a laser or IPL, since they are different technologies, and check that the clinic holds an MOH licence.
Laser hair removal aims at long-term reduction of regrowth, not a promise that every hair is gone for good. It heats pigmented follicles in their growth phase, so treatment is staged, and hair that does return may be finer and lighter. Hormones can bring new growth over time, particularly on the chin and jawline, which is why maintenance is discussed honestly at assessment. White, grey or very fine hair does not respond.
Check that a registered doctor assesses your skin and hair before treatment, and that the wavelength is chosen for your skin type rather than one setting for everyone. Ask which device is used, since IPL, SHR and diode are different technologies. Ask who supervises each session and whom to contact if the skin blisters or darkens afterwards. A written quote after assessment, not a fixed package, is a reasonable expectation.

Laser hair removal works by selective photothermolysis. Melanin in the hair shaft absorbs laser energy, which converts to heat and conducts to the follicular structures that produce hair. Because the target is pigment, hair with little melanin responds poorly, and because hair grows in cycles, treatment is staged across sessions.

Yes, provided the wavelength is appropriate. The 1064 nm Nd:YAG wavelength is less readily absorbed by melanin in the upper skin layers and penetrates more deeply, which makes it the appropriate choice for Fitzpatrick IV to VI. Treating darker skin with a wavelength intended for lighter phototypes carries a risk of epidermal injury and post-inflammatory pigment change.

The 755 nm alexandrite wavelength is strongly absorbed by melanin, which suits Fitzpatrick I to III where dark hair contrasts with lighter skin. The 1064 nm Nd:YAG wavelength is less absorbed by surface melanin and penetrates deeper, which suits Fitzpatrick IV to VI. Neither is preferable in the abstract; they are matched to different skin.

The number of laser hair removal sessions varies with the area, hair characteristics and individual growth cycles. Only follicles in the active growth phase respond at any given session, which is why treatment is staged. The plan is set out at consultation after assessment rather than sold as a fixed package.

Commonly treated areas include the underarms, legs, arms, bikini line, back, chest and face. Suitability for each area, and the appropriate wavelength and settings, are assessed in person.

Most patients describe a snapping sensation with each pulse. Epidermal cooling is used to protect the skin surface and improve tolerance. Comfort varies between individuals and between areas, and is managed during the session.

Suitability is assessed in person. Recent sun exposure or tanning, photosensitising medication, active infection or inflammation in the area, certain skin conditions and pregnancy are among the things considered. Not every patient or every presentation is appropriate for treatment.

Generally not; laser hair reduction does not make treated hair coarser. A rare effect called paradoxical hypertrichosis, in which hair growth increases near a treated area, has been reported, most often on the face and neck in darker skin types. Its cause is not fully understood, and it is one reason settings are chosen area by area and reviewed as treatment progresses.

Laser hair reduction is used for ingrown hairs because fewer and finer regrowing hairs means less of the shaving that drives them, which is why the beard line, neck, bikini line and underarms are common reasons to ask. Response varies, and inflamed or infected bumps are settled before treatment. Where bumps persist, the cause is examined, since folliculitis and other conditions can look similar.

The cost of laser hair removal in Singapore depends on the areas treated, the wavelength and device used, the consumables involved, the number of passes or zones, and whether areas are planned together. A written quote is given at consultation, after Dr Sin Yong has assessed your skin and hair. The consultation also decides whether treatment is advised, so no fixed figure is given in advance.

It can be worthwhile for people with pigmented hair who want less regrowth and accept that treatment is staged and the response varies by area. It is less suitable for white, grey or very fine hair, which responds poorly, for freshly tanned skin, or for anyone expecting every hair to be gone after one visit.

How long laser hair removal lasts depends on the area, hair type, skin type, hormones, the settings used and how closely visits follow the hair cycle. Hair can return over time, and no duration is promised. Review timing, and whether further treatment is advisable, is set at consultation after assessment and adjusted as the skin responds.

Disadvantages include a response that varies, treatment staged across visits, and temporary redness, bumps and warmth. Blistering, burns and darker or lighter patches are uncommon, particularly if the wavelength does not match the skin or the skin is tanned. White, grey or very fine hair responds poorly, and some people need a hormonal cause assessed first.

Often, on lighter skin types, where the 755 nm alexandrite wavelength is strongly absorbed by what melanin the hair does carry. Very fine vellus hair and truly white or grey hair carry too little pigment for any laser to target, and that is said plainly at assessment rather than discovered afterwards.
Yes. Settings for each area are determined by Dr Sin Yong after examining the skin and the hair, and treatment is doctor-supervised rather than run from a fixed protocol.
Yes, they are commonly assessed in the same consultation and planned together. Each area is still set independently, because the skin tone and the hair differ from one area to the next.
It helps to know. Previous treatment changes what hair remains, how it responds and what settings are appropriate, and treatment that was stopped short abroad is one of the commonest reasons patients come in. Bring whatever record you have.
Laser hair removal in Singapore varies by wavelength: longer wavelengths such as 1064 nm Nd:YAG are safer on darker and tanned skin, while 755 nm alexandrite suits lighter skin with dark hair. Dr Sin Yong matches the laser to skin tone and hair colour, and treats a test area first on darker skin.
The physics is the same; the plan differs. Male beard, chest and back hair is denser and coarser, so energy is set lower at first and sessions are spaced to the slower growth cycle of body hair. Beard work needs care around the jawline to avoid patchy lines, and a man who wants thinning rather than clearance says so at assessment. Dr Sin Yong performs every session himself.
