Lasers in Singapore are chosen by target, not by name: a wavelength is absorbed by pigment, by haemoglobin, by water or by collagen, and the pulse decides whether it shatters, heats or vaporises. That is why the same brown mark, red mark, scar or sag is sent to different lasers. This page gathers every laser guide on the site and sorts them by the problem each one answers.

Short answerFind your problem in the table below and read the page it points to. Discrete brown spots usually go to the picosecond laser; inflamed, uneven tone to R2 Glow; melasma to a diagnosis before any laser; superficial scars and pores to FSX; deeper scars to the S3 Resurfacing Lift on fractional CO2; a sagging or overfilled face to the Time Freeze Laser LCLR®. If your skin is Fitzpatrick IV or darker, read the laser for dark skin guide first. Every laser session is performed by Dr Sin Yong.

Key facts
Pigment lasers
T2 Frax Radiance, a picosecond protocol at 785 nm on the DEKA TORO with 532 nm and 1064 nm nanosecond emissions, for sun spots, freckles and selected marks; low-fluence 1064 nm laser toning for PIH and melasma once diagnosed
Inflammation lasers
R2 Glow, long-pulsed 755 nm alexandrite and 1064 nm Nd:YAG, directed at the low-grade inflammation behind dull, uneven tone; R2T2 runs R2 Glow and T2 Frax Radiance as one plan
Resurfacing lasers
FSX Laser, 1540 nm erbium glass and 1927 nm thulium, for fine lines, pores and superficial scars; S3 Resurfacing Lift, fractional CO2 on the DEKA SmartXide Tetra Pro, for deeper acne scars
Collagen-absorbed
The 少女光 laser on the DEKA RedTouch Pro at 675 nm, absorbed by collagen rather than water, for redness, pores and tightening at the reticular dermis
Lifting and remodelling
Time Freeze Laser LCLR®, a long-pulsed 755 nm and 1064 nm protocol with a Sculpting mode, for sagged fat along the jowl and for Sculptra or Ellansé overfill that no enzyme can dissolve; no redness, no downtime
Skin type
Most of Singapore is Fitzpatrick III to V, so wavelength, fluence and density are set for the skin before the device is switched on, and every laser is performed by Dr Sin Yong

Who these guides are for

These guides are for three kinds of reader. The first has a brown mark, a red mark, a scar, a pore pattern or a dull tone and has been told, by a friend or by an advertisement, that a particular laser fixes it; they want to know whether that is true for their mark, in their skin. The second has darker or Asian skin and has either had a dark patch after a laser elsewhere or has been told they are not a candidate; they want to know which lasers are safer in Fitzpatrick IV to VI and which carry the most risk of post-inflammatory darkening. The third is deciding between a laser and something else altogether: a lift, an injectable, a cream, or a referral.

A laser is the right tool when the target absorbs its wavelength and the surrounding skin does not. That is the whole logic of the table below. It is the wrong tool when the problem is in a layer the laser cannot reach, which is why no laser here is sold for melasma without a diagnosis first, why a tethered scar is released by subcision before any resurfacing, why an ice-pick scar goes to TCA CROSS, and why a face that has dropped is assessed for lifting before a skin laser is offered. The laser for dark skin guide sets out the skin-type logic that runs through every page.

What the guides have in common is the approach: the diagnosis is made in person, often with a Wood's lamp or dermatoscope, the wavelength and settings are chosen by Dr Sin Yong for the skin in front of him, a test patch is used where the skin type calls for it, and the plan is reviewed rather than counted. No session numbers or fees are quoted before assessment; the how we quote page explains why. WhatsApp enquiries are answered in English and Chinese.

Which laser for which problem

Each row names the laser or protocol usually considered on this site for that problem, the thing it cannot do, and the page to read. It is a reading guide; the actual choice is made after the skin is examined, and more than one row often applies to the same face.

Three rules that run through every row

“A laser does not know what a brown mark is. It only knows what absorbs it. So the diagnosis is mine to make before the laser is switched on, and if the diagnosis is melasma, the laser waits.”

Frequently Asked Questions

It depends on the pigment. A discrete sun spot or freckle usually goes to the picosecond laser, T2 Frax Radiance on the DEKA TORO. Dull, inflamed, uneven tone goes to R2 Glow, which is directed at the inflammation rather than the deposit. Melasma is diagnosed first and often led by creams and tranexamic acid, with low-fluence 1064 nm toning only where it helps. Hori's naevus needs a wavelength that reaches dermal pigment. The pigmentation removal page sorts these.

Depth decides. Superficial and shallow scars, fine lines and pores go to the FSX Laser, 1540 nm and 1927 nm; deeper boxcar and rolling scars go to the S3 Resurfacing Lift, fractional CO2 on the DEKA SmartXide Tetra Pro. A tethered scar is released by subcision before any resurfacing, because a laser cannot free a tether from above, and an ice-pick scar goes to TCA CROSS. Brown or red marks left by acne are not scars and go to the pigment or inflammation lasers.

Laser is used in dark and Asian skin when the wavelength, fluence and density are chosen for the skin. Most of Singapore is Fitzpatrick III to V, so longer wavelengths such as 1064 nm, lower fluence, lower density on fractional lasers, test patches and strict sun protection are the rule rather than the exception. The risk that cannot be removed entirely is post-inflammatory darkening, which is why the laser for dark skin guide is the first page to read if that describes your skin.

Pico fires picosecond pulses that fragment pigment mainly by pressure, which suits a discrete deposit. Laser toning is low-fluence 1064 nm delivered in gentle passes to nudge tone, PIH and diagnosed melasma. R2 Glow uses long-pulsed 755 nm and 1064 nm energy on the low-grade inflammation that keeps producing pigment, leaving the surface intact. R2T2 runs R2 Glow and T2 Frax Radiance together when both the deposit and its driver are present.
