What is Curas Advanced Nano Laser?


The Nd:YAG laser is a popular laser toning treatment and has served as the standard for pigmentation and tattoo removal in Singapore for over a decade. Numerous clinical studies have demonstrated its effectiveness in treating various pigmented lesions on the skin. However, traditional Q-switch Nd:YAG or Nd YAG laser treatment has limitations, particularly in providing significant improvement for melasma. Moreover, melasma tends to recur after the treatment is discontinued.

The advanced Q-switch Nd Yag laser represents a significant improvement over the previous generation of Q-switch lasers. It features an enhanced laser system that optimizes performance and includes various laser modes designed to treat post-inflammatory hyperpigmentation (PIH) and melasma more effectively. Let’s explore why.


The advanced Q-switched Nd:YAG laser system, CuRAS, offers optimal performance for the treatment of tattoos, melasma, non-ablative resurfacing, and pigmented lesions. With dual wavelengths (1064/532nm) and three different handpieces, doctors can address a variety of skin needs for their patients.

Stable and Uniform

Its auto-calibration function guarantees precise and stable energy with a uniform beam profile, regardless of whether the laser is used consistently throughout the day. (Note: Some laser systems exhibit inconsistent laser output after prolonged use.) A real-time monitoring system enables our doctors to check the consistent delivery of the laser.

Fast and Effective

The PTP mode delivers the high peak energy into twin pulse with short intervals for a faster and safer treatment by minimalizing the risk of and pain and side effect during treatment. The twin pulse with a high peak energy feature allows pigmentation to be treated with significantly less pain.

Top Hat Laser Beam Profile

The even top-hat beam profile of CuRAS means that there is a uniform beam profile regardless of various energy settings. CuRAS and its even hat shape beam can deliver uniform and accurate – high-quality beam – on the target area without affecting any surrounding tissue for safety and effectiveness.

Safe and Easy

The spot size of the zoom handpiece device is adjustable from 2 – 10mm with 1 mm adjustments to enable you to select the appropriate spot size for efficient treatments easily. An automatic two-way communication function between the control system and the spot size setting makes spot size adjustment much easier and safer for the doctor.

Preset Protocol & Storage Mode

Preset protocols and storage modes can be set, such as the expert melasma treatment mode, involving melasma mode, Q switch mode and long pulse (genesis) mode for effective treatment of melasma. This is curas patent melasma treatment.

Tattoo Removal

1064 wavelengths allow the removal of black and dark blue tattoo ink effectively, especially with a stable and more efficient laser top-hat beam profile. 532 wavelengths allow red tattoo removal with minimal blistering compared to conventional nd: YAG lasers. Therefore, these dual wavelengths allow good clearance of most tattoo ink.

Pigmented Lesions

Curas laser and its even hat shape beam profile are effective to treat most pigmented lesions from superficial pigmented lesions such as freckles, lentigo, and other vascular lesions like age spots with a low incidence of PIH.  the treatment also provides the optimal performance for the treatment of tattoo ink removal, melasma, vascular lesions, skin rejuvenation, non-ablative resurfacing and pigmented lesions. This is because of the stable top-hat laser energy profile, which is precise. Therefore lower energies are used to treat these lesions compared to traditional nd:YAG lasers. The unique features of this high-quality beam allow the laser to be used safely on all skin types.


Curas is currently one of the rare advanced Q switch Nd YAG laser system that can offer various modes to address Melasma and pigmented dermal lesions. Melasma mode (at 100 ns pulse duration) has a stronger photothermal effect which is more efficient to clear larger, deeper pigmented lesions. (Photothermal effect has been shown in clinical review papers to have a better pigment clearance effect than photoacoustic effects in pico laser, you can read about it here – link to everything you need to know about pico laser) Genesis mode (at 100 ms) can help to stimulate collagen in the deep dermis layer and also add the additional photothermal resolution of melasma. These modes do not exist in previous conventional Q switch machines.

Carbon Peel

It is controversial the value of carbon peel with Q switch nd:YAG laser. The idea is to coat the superficial skin and skin pores with a layer of carbon, and when the laser vapourises the carbon, it has a skin peeling and pore tightening effect. However, that also releases various carbon particles into the air and can be breathed into the lungs. In addition, these particles can also spoil the laser machine easily. In our clinic experience, the skin peeling and pore tightening effect are often short-lived. Therefore we prefer a proyellow laser peel or a chemical peel to achieve the same effect.

Skin Rejuvenation

This is the strength of the CURAS advanced nanolaser in various laser modes that allow the delivery of laser pulses at different pulse duration, therefore targeting different depths of the skin. For example, genesis mode targets deep dermis while melasma mode and q switch mode target more superficial skin. The even and adequate delivery of well-distributed laser pulses will allow a more thorough skin rejuvenation and pore reduction for patients.

Lentingo and Freckles

Solar related lentigines or lentigo respond very well to 532 wavelengths of advanced q switched laser. Most such superficial pigments should completely clear in 2-3 sessions. Because of the high-quality beam and more efficient use of laser energy pulses, these lesions can be cleared at significantly lower energies compared to conventional q switch lasers and even certain pico lasers. What that means is a significantly lower risk of PIH, which is a common risk for most q switch nanolaser or pico lasers.

Post-inflammatory hyperpigmentation

Conventional q switch lasers and pico lasers have limited success in treating PIH. That is photoacoustic power of these laser systems has not been particularly successful in reaching and dispersing PIH, which are larger and deeper pigment lesion. In addition, excessive photoacoustic power can itself provoke more PIH to occur. Therefore, at longer pulse durations, both the genesis mode and melasma mode, which greater photothermal effective but still within the TRT (thermal relaxation time) of the dermis, can cause more PIH clearance.

Yes, Curas advanced nanolaser that utilises high peak power is a safe laser treatment for any skin type with minimal complications. A fractional handpiece is also an option to decreasing thermal damage in the skin.

Curas laser treatments, with their more efficient energy settings, allow the treatment of most pigments with significantly less pain and discomfort. Curas is known to deliver uniform high peak power for better results, which has its significant differences to single-pulse laser energy treatments.
Most patients experience an immediate skin brightening, while pigment resolution is best seen after 3-4 weeks. There is redness and scabbing seen for freckles and lentigines treatment.
It is best to do your CURAS treatments every 3-4 weeks to allow adequate skin rest and to avoid complications such as PIH and hypo-pigmentation.
