Long Pulse Nd:YAG Laser — Deep Hair Removal Technology for All Skin Types: Treatment Areas, Sessions, and Results

Long Pulse Nd:YAG

Long Pulse Nd:YAG Laser in the Cool Yag 1064 Program

The Long Pulse Nd:YAG is one of the most popular hair removal lasers in Thailand and is the device used in V Square Clinic’s Cool Yag 1064 program. Its main strength lies in its ability to deliver energy deep into the hair root, allowing for efficient, long-lasting hair removal suitable for all skin tones and all hair types, including fine or coarse hair. It’s particularly effective in delicate areas such as the face and intimate zones.

If you’re researching this technology and wondering how it differs from other YAG Lasers or hair removal systems, which body areas it can treat, how many sessions are required, and how to prepare before treatment, this article will walk you through everything in detail.

What Is Long Pulse Nd:YAG ?

Long Pulse Nd:YAG is a high-performance laser hair removal technology that targets the hair root directly, reducing the number of sessions needed while minimizing the risk of ingrown hairs. It is suitable for all skin tones and hair textures — from thick and coarse to fine and light — making it one of the most effective options for precise hair removal in areas such as the underarms, face, and bikini line.

The most trusted and widely used model is the Long Pulse Nd:YAG Light B Evo by Quanta System, Italy, which is certified by the U.S. FDA, European CE, and Thai FDA. This advanced system features:

  • High energy accuracy and stability, effectively destroying hair follicles at the root while minimizing the risk of skin irritation.
  • Adjustable energy levels tailored to individual skin types and hair thickness.
  • Fast and efficient performance, removing up to 15–20% of hair per session, reducing both treatment time and total sessions required.
  • User-friendly design, with precise energy control and an optimized operating system.
  • Global safety certifications ensure both efficacy and safety for patients.

Some individuals may experience mild discomfort during treatment, so cooling systems such as cold air devices, cooling gels, or topical anesthetics are often used to enhance comfort.

At V Square Clinic, we have developed a specialized treatment called Cool Yag 1064, which combines the Long Pulse Nd:YAG Light B Evo with the Cryo 7 cold air cooling system. This integration allows for precise, safe, and more comfortable hair removal — maximizing both performance and patient comfort.


How Does the Long Pulse Nd:YAG Work ?

The Long Pulse Nd:YAG laser works by using heat energy to selectively target and destroy hair follicles. Melanin pigment in the hair root absorbs the laser’s energy, causing a rise in temperature that destroys the follicle without damaging the surrounding skin. With consistent sessions, hair growth gradually becomes slower, finer, and less dense over time.

Who Is Long Pulse Nd:YAG Suitable For ?

Long Pulse Nd:YAG hair removal is suitable for both men and women, and especially beneficial for:

  • Those seeking long-term or permanent hair removal without frequent maintenance.
  • Individuals with skin irritation, ingrown hairs, or folliculitis caused by shaving, waxing, or other methods.
  • People with thick or dense hair who want smoother, hair-free skin.
  • Those looking to reduce sweat and bacterial buildup in areas like the underarms, back, or intimate regions.
  • Individuals who want to feel more confident when wearing revealing or sleeveless clothing.
  • People who struggle with makeup adhesion or poor skincare absorption due to facial hair.
  • Those who want to save time and long-term costs by reducing the need for frequent hair removal.

Which Areas Can Long Pulse Nd:YAG Treat and How Long Does Each Session Take ?

Thanks to its precise and selective energy delivery, the Long Pulse Nd:YAG laser can safely treat even delicate skin areas without damaging surrounding tissue. It is gentle yet powerful, making it suitable for all parts of the body — from the face and sensitive intimate zones to larger areas such as the underarms, chest, abdomen, arms, legs, and back.

Long Pulse Nd:YAG treatment areas
Treatment areas for Long Pulse Nd:YAG

Each Long Pulse Nd:YAG hair removal session typically takes 20–60 minutes per area, depending on the treatment zone, hair density, and body size.

Here’s an approximate breakdown:

  • Underarms: 20 minutes per session
  • Genital area (Brazilian+ including anus): 30–45 minutes per session. If treating only the bikini line, the duration will be shorter.
  • Chest: 30–45 minutes per session
  • Abdomen: 30–45 minutes per session
  • Full face: 30–45 minutes per session; the upper lip, beard, or mustache area requires less time
  • Arms: upper or lower arm — 30 minutes; full arms — 60 minutes
  • Legs: upper legs — 45–60 minutes; lower legs — 30–45 minutes; full legs — 75–105 minutes
  • Back: 45–60 minutes per session

Note: If a topical anesthetic or cooling gel is applied for comfort, expect an additional 20–30 minutes of preparation time.

How Is Long Pulse Nd:YAG Different from Other YAG Lasers ?

The Long Pulse Nd:YAG differs from other types of YAG lasers mainly in its wavelength, penetration depth, and treatment applications.

Simply put, “YAG Laser” is a general term for lasers that use Yttrium Aluminum Garnet (YAG) crystals as their gain medium. Different dopants (minerals) are added to the crystal, producing different wavelengths and treatment depths suitable for various medical or aesthetic purposes — from hair removal and skin rejuvenation to surgery and dermatological treatments.

Laser TypeWavelengthKey FeaturesCommon Uses
Nd: YAG Laser / YAG Laser1064 nmContains Neodymium ions in its gain medium; strongly absorbed by melanin pigments.Hair removal, wrinkle reduction, and pigmentation treatment.
Er:YAG Laser / Erbium YAG Laser2940 nmContains Erbium; best absorbed by water molecules, stimulates collagen, and can precisely ablate deep skin layers.Acne scar treatment, pore tightening, pigmentation removal, and skin resurfacing.
Ho:YAG Laser / Holmium YAG Laser2100 nmContains Holmium; efficiently absorbed by water, enabling precise tissue incision and fiber-optic energy delivery.Medical surgery such as lithotripsy (stone removal) and tissue cutting.
Long Pulse Nd:YAG1064 nmEmits energy in millisecond pulses with low fluence but longer duration, producing deep heat while protecting the skin. Ideal for destroying hair roots and reducing regrowth.Hair removal on the face, body, and intimate areas.
Gentle YAG1064 nmA standard YAG laser that uses pre-spray cooling with non-adjustable settings; typically requires numbing cream or cold compress.Effective for thick, coarse hair removal.
Q-Switched Nd:YAG Laser532 nm, 1064 nmDelivers ultra-short, high-energy pulses in nanoseconds for pigment fragmentation.Tattoo removal and post-acne pigmentation.

In summary, the Long Pulse Nd:YAG laser is the preferred choice for hair removal, as it penetrates deeply to destroy the hair root, reducing regrowth while being safe for all skin tones and suitable for multiple treatment areas.


Comparing Long Pulse Nd:YAG with Other Hair Removal Lasers

Each hair removal laser system varies in suitability depending on skin tone, hair color, and hair thickness. Besides Long Pulse Nd:YAG, there are several other popular laser types — including Diode, Alexandrite, Ruby, and IPL — each with unique advantages and limitations. The comparison below summarizes the key differences to help determine which option is most suitable.

Comparison of Hair Removal Laser Technologies

In Thailand, where most people have light to medium tan skin and dark-colored hair, the most suitable and effective options are Long Pulse Nd:YAG and Diode lasers.

Among these, Long Pulse Nd:YAG remains the most popular choice because it can treat all areas, including sensitive zones such as the face, underarms, and intimate regions. When paired with a cold air cooling system, it greatly reduces discomfort while maintaining high precision and safety.


How to Prepare Before Getting a Long Pulse Nd:YAG Treatment

Preparing for long-pulse Nd:YAG laser hair removal is simple. Patients should allow hair to grow naturally and avoid plucking, waxing, or using depilatory creams, as these can affect the amount of melanin in the hair roots, reducing laser effectiveness.

Follow these general pre-treatment guidelines:

Key advantages of Cool Yag 1064 at V Square Clinic


Frequently Asked Questions About Long Pulse Nd:YAG

Will Hair Grow Back After Completing the Full Course ?

If you complete a full course of Long Pulse Nd:YAG sessions, hair regrowth usually stops for quite a while. However, hormonal and individual biological factors can still affect the results. In most cases, any regrowth is finer and lighter, and maintenance sessions once or twice a year help keep the skin smooth.

Does Long Pulse Nd:YAG Hurt ?

Most patients describe the feeling as a light snap of a rubber band — quick and tolerable.

At V Square Clinic, the Cool Yag 1064 program includes the Cryo 7 cooling system, which provides cooling air at up to –30°C with 9 adjustable levels. This keeps the skin cool and relaxed while greatly reducing discomfort throughout treatment.

Can Men Get Long Pulse Nd:YAG Laser Hair Removal ? Is It Different from Women ?

Yes, men can get Long Pulse Nd:YAG treatment on all areas, including the beard, mustache, underarms, legs, arms, and Brazilian area. Visible results typically appear after 5–8 sessions.

While men achieve results comparable to women, some may require additional sessions due to hormonal factors and thicker, faster-growing hair follicles.

Can Multiple Areas Be Treated in One Session ?

Yes, multiple areas can be treated in one session, depending on the treatment zones and patient comfort. For smaller areas like the face or underarms, combined treatments are common.

For larger zones such as the legs, back, or chest, sessions are usually scheduled separately since they require more time and specific positioning to maintain comfort.

What’s the Difference Between Long Pulse Nd:YAG and GentleYAG ?

GentleYAG uses a Dynamic Cooling Device (DCD) that sprays cryogen to cool the skin instantly before each laser pulse.

In contrast, Nd:YAG systems do not include DCD but can integrate alternative cooling methods — such as topical anesthetics, cooling gels, or advanced Cryo 7 cold air systems, which provide adjustable cooling without direct skin contact for greater comfort.

Can Long Pulse Nd:YAG Be Used for Skin Rejuvenation ?

The Long Pulse Nd:YAG laser is mainly used for hair removal. For skin rejuvenation or brightening, other YAG-based lasers such as Er:YAG or Q-Switched Nd:YAG are better options.

For example, the Fotona SP Dynamis system combines both Er:YAG and Nd:YAG wavelengths to treat different skin layers, boost collagen production, even out skin tone, and refine texture for a smoother, brighter look.

Is Long Pulse Nd:YAG Worth It ?

Yes — Long Pulse Nd:YAG is one of the most effective and reliable hair removal options available today. It works safely across all skin tones and hair types, providing long-lasting results and significantly reducing regrowth when done consistently. When paired with an advanced cooling system, discomfort is minimized, and patients experience smoother, more comfortable sessions.

At V Square Clinic, our Cool Yag 1064 program uses the Long Pulse Nd:YAG Light B Evo laser — certified by the U.S. FDA, European CE, and Thai FDA — along with the Cryo 7 cold air system, which allows energy delivery without numbing cream or cooling gel. Each session is supervised by trained physiotherapists, ensuring both safety and visible results from the very first treatment.
