Laser hair removal: three-wavelength system and single-wavelength system

Update time : 2024-02-28 15:08:54

Consumers’ endless desire for hairlessness has driven innovation and increased the popularity of laser hair removal treatments.
Choosing the laser technology that best suits your client is essential to the success and profitability of your clinic and to ensure that your treatment is safe and effective.
However, with so many devices on the market, it is important to understand the main differences between these technologies.
Today, I focus on the difference between three-wavelength technology and single-wavelength technology. The power of three is just a power greater than one. The three-wavelength combination is a relatively new innovation.
The wavelength of alexandrite is the shortest of the three. It allows the maximum absorption rate of the melanin chromophore. This provides the best solution for the widest range of hair types and colors, especially thin and light hair.
The diode wavelength is very effective for darker skin types, but less effective for lighter, thinner hair. Its deep penetration level provides the best results for skin types I to IV.
The YAG wavelength is a longer wave. It can reach deeper hair follicles that hold more terminal hairs. It is also safer to use on dark skin.
Modern lasers such as three-wavelength diode laser machine combine three wavelengths. This allows for higher coverage and excellent results.

The triple laser transmits energy downwards, reaching different depths of the hair follicle, and even causing hair follicle damage.
three-wavelength diode laser machine uses volumetric heating of dermal tissue to change the function of hair stem cells, thereby affecting regeneration.
Another major difference between three-wavelength lasers and single-wavelength lasers is how they work. Standard lasers use the “fire” method, which works by exposing the hair follicle to a single high-energy pulse.
This can be quite painful for your customers and brings a higher risk of complications. It is also important to note that treatment with a single-wavelength laser is a slower process.
Instead of exposing hair follicles to a single high-energy pulse, three-wavelength diode laser machine uses a dynamic protocol to provide fast, comfortable and effective hair removal for most skin types. It works by gradually heating the dermis and destroying hair follicles, while avoiding damage to surrounding tissues.
The three-wavelength diode laser machine mobile phone slides on the skin with a brush-like movement to achieve full coverage, while the contact cooling system ensures almost painless and effective hair removal. The combination of the latest technology and innovative design provides a safe, fast and effective hair removal solution.
