Every laser used at IN Eternity Clinic, what it targets and which concern it suits. Medical Director Dr Sin Yong chooses the laser and settings after identifying the cause and your skin type.
WhatsApp to Enquire →Key facts ↓Laser treatment in Singapore covers several different machines, each absorbed by a different target: pigment, ink, blood vessels, water or collagen. IN Eternity Clinic uses picosecond and Q-switched lasers for pigment and tattoos, CO2 and FSX fractional lasers for scars and texture, the DEKA RedTouch Pro 675 nm laser (Shaonu Guang) for redness and pores, and the Lutronic Clarity II for hair. The laser is chosen after the cause is diagnosed.
A medical laser delivers light of one wavelength in controlled pulses. Each wavelength is absorbed by a particular target in the skin, called a chromophore: melanin in pigment and hair, haemoglobin in blood vessels, water in every cell, and tattoo ink. When the pulse is shorter than the time the target takes to cool, the heat or pressure stays inside the target and the surrounding skin is spared. This principle, selective photothermolysis, is why one laser clears a sun spot while another resurfaces a scar.
Three settings decide what a laser does: the wavelength (what absorbs the light and how deep it reaches), the pulse duration (picosecond and nanosecond pulses shatter pigment; millisecond pulses heat hair follicles and collagen) and the energy. Lasers are also described as ablative, removing a thin layer or columns of skin, or non-ablative, heating beneath an intact surface. Fractional lasers treat the skin in microscopic columns and leave bridges of untouched skin between them, so healing starts from healthy tissue and recovery is shorter.
In practice this means there is no single “laser treatment”. The question is always which target is responsible for the concern, and which laser reaches it safely in your skin type.
IN Eternity Clinic on Orchard Road is a designated DEKA Centre of Excellence (2026). These are the lasers in use, what each one is, and where it is described in detail.

Several of Dr Sin Yong’s named protocols are built on these lasers: Time Freeze Laser LCLR® for lifting, the Luminescence Laser Lift for scars and texture, 4D Scar Reconstruction for layered acne scars and the S3 Resurfacing Lift. The MonaLisa Touch intimate treatment uses DEKA’s fractional CO2 technology, and H2LT is a low-level laser for thinning hair that does not heat tissue at all.
Pigment is treated with very short pulses that break melanin into fragments the body then clears. Defined spots such as sun spots, freckles and some birthmarks respond to picosecond or Q-switched pulses on the Fotona StarWalker PQX or DEKA TORO; the detail is on laser treatment for pigmentation, freckles removal and age spot removal.
Melasma is different. It is driven by hormones, heat and light as well as pigment, and strong pulses can make it darker. It is treated with low-energy laser toning as one part of a combined melasma plan, alongside skincare and sun protection. Settings are deliberately gentle: depigmentation has been reported after frequent, high-energy toning in Asian skin, which is why sessions are spaced and reviewed. For a guide by type, see pigmentation treatment in Singapore.
Scars and texture are a collagen problem, so they need lasers that remodel the dermis. The DEKA Tetra Pro CO2 laser vaporises fine columns of skin, and its SCAR3 (S3) mode is designed for atrophic acne scars; recovery is usually about a week of redness and fine crusting. The FSX laser heats without breaking the surface, so it suits texture, open pores and fine lines with lighter recovery over more sessions. Both are explained on fractional laser in Singapore.
Deep or mixed acne scars usually need more than one tool, which is why acne scar treatment at the clinic often combines laser with subcision, TCA CROSS or skin boosters. Pores that come from oil rather than lost support respond to different steps; enlarged pores treatment and the carbon laser peel explain the choice.
Redness comes from dilated or reactive blood vessels and an inflamed barrier, not from pigment. The DEKA RedTouch Pro 675 nm laser (少女光) works under contact cooling with the surface intact, and is used at the clinic for redness-prone skin, pores and texture; it can help control rosacea-related redness but does not cure rosacea. The wider plan, including triggers and prescription care, is on rosacea treatment in Singapore.
For active acne, laser is an add-on to medical treatment rather than a replacement for it. Laser acne treatment sets out where the 675 nm and Nd:YAG lasers fit, and why acne is settled before scars are resurfaced.
Lasers tighten mainly by heating the dermis so it contracts and remodels, which helps crepey skin and early laxity. Time Freeze Laser LCLR® is Dr Sin Yong’s dual-wavelength laser protocol for a non-surgical lift in a fuller lower face, where it tightens and takes away the excess along the jowl and under the chin. The Luminescence Laser Lift combines non-ablative scar and texture work with a lifting step in the same session.
Deeper sagging is usually answered by focused ultrasound or radiofrequency rather than laser; face lifting treatment in Singapore compares them by layer.
Hair removal. The Lutronic Clarity II pairs a 755 nm Alexandrite laser, which suits finer hair and lighter skin, with a 1064 nm long-pulsed Nd:YAG, which penetrates deeper and is the safer choice for darker skin. Only follicles in the growth phase respond, so it is a course. See laser hair removal in Singapore.
Tattoo removal. Picosecond and Q-switched wavelengths are matched to each ink colour and fade a tattoo over a course spaced weeks apart; complete clearance is not always possible. See tattoo removal in Singapore.
Small benign bumps. Dermatosis papulosa nigra and most other small benign bumps, such as syringomas, seborrhoeic keratoses and sebaceous hyperplasia, are treated with the DEKA Tetra Pro CO2 or an Erbium:YAG laser once they are confirmed to be benign. Xanthelasma and selected moles are assessed individually, and a mole that needs a diagnosis is not lasered.
“The laser is the last decision, not the first. Until we know whether a mark is pigment, blood vessels or scar, there is no right laser to choose.”
| Pico / Q-switched | Laser toning | Non-ablative fractional (FSX, 675 nm) | Ablative fractional CO2 | |
|---|---|---|---|---|
| Main target | Pigment, ink | Diffuse pigment, tone | Dermal collagen, texture | Scar tissue, deep texture |
| Surface | Intact | Intact | Intact | Columns of skin removed |
| Usual recovery | Redness for hours; small spots may darken and flake over a week | Mild redness for hours | Redness for a day or two | About a week of redness and fine crusting |
| Sessions | One to a few for spots; more for tattoos | A course, spaced and reviewed | A course | Often one to three, spaced months apart |
| Pigment risk in Asian skin | Low to moderate; settings matter | Low with gentle settings | Low | Higher; planned with sun care and pre-treatment |
These are not ranked against each other; they do different jobs. A plan for mixed concerns often uses two, for example pico for spots and FSX for texture, timed so the skin recovers between them.
Most people in Singapore have skin types III to V, which contain more melanin. That is not a reason to avoid laser, but it changes how it is done. The main risk is post-inflammatory hyperpigmentation: temporary darkening after heat or injury to the skin. Studies of fractional resurfacing in Asian patients link it to higher energy and density, so settings are chosen conservatively and adjusted session by session.
Aftercare in the local climate is covered in detail in Singapore humidity and post-laser care.
General clinical observations used at consultation; they describe what is checked, not any individual result.
Laser removes what is there; it does not tell you what it was. These signs need a diagnosis first, and some need a referral.
Where any of these apply, the spot is examined and, if needed, sampled or referred. A pigmented lesion that might be a skin cancer is never treated with laser.
There is no single price for “laser treatment”, because the laser, the area, the number of sessions and any combination all change the total. A single spot is costed differently from a full-face course, and ablative resurfacing differs from toning.
At IN Eternity Clinic the plan and its cost are written down after the assessment, before anything is agreed. The consultation fee is S$120, waived with any medical treatment. Detailed guides cover pico laser prices and tattoo removal costs.
Pigment lasers (pico and laser toning), fractional resurfacing for scars and texture, and laser hair removal are among the most frequently requested. Which one suits you depends on what is causing the concern, which is established at assessment.
It depends on the target. Pigment responds to picosecond or Q-switched pulses, scars to fractional CO2 or FSX, redness to the 675 nm laser and hair to the Lutronic Clarity II. Dr Sin Yong identifies the cause and your skin type before choosing.
Most lasers feel like quick snaps or warmth. Numbing cream is used for resurfacing and some pigment treatments, and cooling is built into several devices. Comfort varies between people and areas.
It ranges from a few hours of redness after toning to about a week of redness and fine crusting after fractional CO2. Pico spot treatment can leave small darkened spots that flake within a week or so.
It varies with the laser and the concern. A few defined spots may clear in one to a few sessions; melasma, scars, tattoos and hair removal need a course. The number is estimated at assessment and reviewed as you go.
It can. Temporary darkening after heat or injury is the main risk in skin types III to V. Conservative settings, spacing sessions, treating calm skin and strict sun protection reduce it, and it usually fades with care.
Laser results are not permanent in the sense that skin keeps ageing and pigment can return with sun and hormones. Scar remodelling and hair reduction can be long-lasting; pigment and tone are usually maintained.
Look for a licensed medical clinic where a doctor examines you before treatment, names the laser and explains why it suits your skin type, and tells you plainly when laser is not the right answer. IN Eternity Clinic holds MOH licence MDS/001/252.
