Understanding Laser Hair Removal
Laser hair removal is considered to be one of the most popular cosmetic procedures for removing unwanted hair from any part of the body. It uses a concentrated beam of light to target hair follicles, which ultimately destroys them, resulting in permanent reduction of the hair growth.
While laser hair removal was first approved by the FDA in the year 1997, new advancements have been made in the technology to make the procedure more efficient and effective. In this article, we will discuss the latest innovations in laser hair removal that aim to improve the overall experience of the patients.
1. Diode Lasers
Diode lasers have been around for a while; however, they have recently gained popularity due to their efficacy in treating all skin types, including darker complexions. One of the significant limitations of laser hair removal is that it works best on light skin tones with dark hair. The melanin in dark or tanned skin has the potential to absorb laser energy, which can cause burns or visible spotting.
Diode lasers work by sending a longer wavelength of light that can bypass the epidermis to target the hair follicle without causing any harm to the surrounding skin. Recent modifications in diode laser technology have allowed for faster treatment times, which can save both time and money for the patient.
2. Cooling Devices
Prior to the advancements in cooling devices, laser hair removal was sometimes known to be an uncomfortable or even a painful experience. However, modern cooling devices help to mitigate the risk of pain during the procedure.
A cooling device is attached to the handpiece or the laser head that helps to reduce discomfort and prevent overheating. This device works on the principle of cryogen spray or wave emission, which cools the skin right before the laser hits it. This allows the laser to penetrate the skin more deeply, increasing its effectiveness and improving the overall hair reduction results.
3. Alexandrite Lasers
Alexandrite lasers are considered to be the fastest lasers used in laser hair removal. They emit light at a wavelength of 755nm, which enables them to target a broader area of skin, thereby allowing clinicians to complete treatments in significantly less time.
The frequency of the Alexandrite laser also makes it perfect for treating larger areas of the body, such as the back, chest, or legs, while also being effective for smaller areas like the face or bikini line. It is important to note that Alexandrite lasers are most effective when used on those with fair skin and darker hair.
4. Nd: YAG Lasers
Nd: YAG lasers are the most diverse of all laser types, which is why they are often used in tattoo removal, skin rejuvenation, and hair removal. It emits a wavelength of 1064nm and is most effective on darker skin types. This laser is unique as it can actively treat embedded hairs, which diode and Alexandrite lasers often miss.
Another advantage of Nd: YAG lasers is that they offer a degree of customization. This means that clinicians can adjust the spot size, pulse length, and fluence, to cater to the specific needs of individual patients.

Conclusion
As technology continues to improve, laser hair removal will become an increasingly popular option for those looking to eliminate unwanted hair. The advancements in cooling devices, diode, Alexandrite, and Nd: YAG lasers, demonstrate the laser industry’s commitment to making this procedure more effective, comfortable, and efficient, highlighting a promising future in this field.
