Types of Laser Hair Removal Explained

People have been finding ways to get rid of unwanted body hair since the beginning of time. Ancient Egyptians (mainly women) were known for removing all of their body hair as a sign of cleanliness and purity. They created their own wax from sugar, oil, and lemon juice—a primitive form of sugaring. Tweezers made from seashells were also common during that time. These days, hair removal has become a global industry, offering a range of services from waxing to laser hair removal.

In recent years, laser hair removal has gained popularity due to its long-lasting results, technological advancements, and increased availability. When compared to other hair removal options, it’s relatively pain-free. While areas such as the legs generally don’t hurt at all, underarms are known to be the most painful. However, most people are so happy with the results that they return for follow-up treatments. Think about it—imagine a world where you never have to shave your underarms again.

There are many types of laser hair removal, and at Nirunda Clinic in Bangkok, our team of certified dermatologists will help you choose the option that’s best suited to your needs. Before booking your free consultation, let’s dive deeper into how laser hair removal works and the different types of lasers involved.

How Laser Hair Removal Works

Laser hair removal targets the pigment in hair follicles. It does this by utilizing selective photothermolysis, a technique that employs specific wavelengths to target and destroy the hair follicle without damaging the surrounding skin. These wavelengths of light get absorbed by melanin, which is the pigment in the hair follicles. Science aside, laser hair removal is a great option for those seeking a pain-free option with long-lasting results. Understanding the different types of laser hair removal will help you choose the one that’s best suited for your skin and hair type.

It’s also worth mentioning that laser skin removal isn’t recommended on tattoos as it “can lead to fading, blistering, and discomfort, among other issues.” Most clinics will maintain a gap of around 3cm from your body art to avoid impacting the ink.

Common Laser Technologies Explained

Now that we’ve mentioned the importance of choosing the right laser, let’s take a closer look at the different types of lasers used for hair removal.

• Ruby Laser (694 nm)

One of the earliest lasers used in hair removal, the Ruby Laser is most effective for treating dark hair on light skin tones (Fitzpatrick I–III). While not as commonly used today, it remains a safe and precise option for those with pale skin and dark hair.

• Alexandrite Laser (755 nm) 

Known for treating larger areas quickly due to its deep and efficient penetration and fast repetition rate, the Alexandrite Laser is a popular choice for those with lighter to olive skin tones (Fitzpatrick I–III).

• Diode Laser (800–810 nm)

One of the most commonly used lasers for hair removal, the Diode Laser offers both deep penetration and balanced melanin absorption. Due to this, it is effective on most skin tones, especially those with Fitzpatrick skin types I–IV. It is a popular choice for coarse and thick hair.

• Nd:YAG Laser (1064 nm)

Known to minimize the risk of pigmentation issues, the Nd:YAG Laser is best for darker skin tones (Fitzpatrick IV-VI). It boasts deeper skin penetration with lower melanin absorption. Although less effective on light-colored and fine hair, it is still a popular choice, especially for treating larger areas.

• Intense Pulsed Light (IPL)

Not a laser but a broad-spectrum light treatment, ILP focuses on hair reduction rather than removal. Because it uses multiple wavelengths to target the melanin in the hair, it is less precise than a laser. It works best on light to medium skin tones (Fitzpatrick I–III) with dark hair. While it’s ideal for large areas, it will require more sessions.

Advanced Multi-Wavelength Systems at Nirunda

Here at Nirunda Aesthetic Clinic, we proudly offer four types of laser hair removal: Soprano Ice Platinum (SHR technology),  Cutera CoolGlide, Motif™ elōs Plus, and Lux RS. These highly advanced multi-wavelength systems offer a multifaceted approach to hair removal.

• Soprano Ice Platinum (SHR technology) 

This advanced system combines Alexandrite, Diode, and Nd:YAG wavelengths to effectively treat all skin and hair types. Its SHR in-motion technology, paired with a built-in cooling system, ensures a virtually painless hair removal experience.

• Cutera CoolGlide

This four-wavelength high-intensity laser uses a Nd:YAG laser, making it safe and effective for all skin tones. Its continuous cooling system not only minimizes irritation but also makes for a practically painless experience.

• Motif™ elōs Plus

Using a Diode Laser combined with IPL technologies, Motif™ elōs Plus is a highly effective and popular choice. By using lower light energy, it greatly reduces the risk of skin damage. It is safe and effective on a wide variety of skin tones.

• Lux RS

Not a laser but a pulsed light system, Lux RS has been specifically designed for lighter skin types with dark hair. It’s best suited for larger areas, such as the legs or back, and utilizes blended light energy for painless and efficient hair reduction.

What to Expect at Nirunda Clinic

We typically recommend starting with 3 to 8 sessions, spaced 4 to 8 weeks apart, but this varies greatly from client to client. During your meeting with one of our laser hair removal experts, you will be provided with a bespoke program to suit your needs.

Before getting a laser hair removal session, refrain from plucking, tweezing, or waxing for at least 4 weeks. You will also need to avoid direct sunlight for 2 weeks, as this can make the skin more prone to irritation. Prior to your treatment, please shave and thoroughly clean the area. We also recommend avoiding anti-inflammatory drugs, such as Aspirin, that could increase the risk of bleeding for at least 24 hours before treatment.

After your session, you must follow the specific after-care advice provided to you by the certified dermatologists at Nirunda. Once again, you will need to avoid direct sunlight for roughly 2 weeks. Apply a cold compress if you are experiencing discomfort or swelling. Avoid the gym or any activity that might cause excess sweating for at least 24 hours. Lastly, avoid body scrubs and keep the area well moisturized.
