When it comes to laser treatment, choosing the right wavelength and laser equipment is only the first step. The effectiveness of laser treatment is also determined by other parameters, including fluence, spot size, pulse duration, and frequency.
High energy can improve the efficacy of treatment, but too much can cause burns and scarring. On the other hand, too little energy can lead to suboptimal results. The energy used in treatment should be adjusted according to the depth, size, and pigment of the hair follicles.
The spot size determines the penetration depth of the laser. A larger spot size scatters less and provides greater penetration depth, which reduces the required laser energy. A larger spot size also allows for quicker and more convenient treatment. For example, hair removal requires a spot size larger than 10mm.
Pulse duration is another important parameter. It must be carefully controlled to prevent skin burns and ensure optimal results. The recommended pulse duration is generally between 10 and 40ms.
Frequency is the parameter that controls the rhythm of the treatment process. A faster frequency is preferred to reduce the treatment time. However, if the treatment is not performed correctly, overlapping treatment areas can cause burns.
Even after adjusting the parameters, the density of the treatment area can also affect the results. Therefore, the skill level of the practitioner is crucial for effective laser treatment. It is important to choose a reputable treatment center based on quality rather than just price or guarantees.
In summary, the effectiveness of laser treatment depends on various parameters, and the treatment process is more complex than many people realize. It is essential to choose a professional and experienced practitioner who can properly adjust the parameters to achieve optimal results.
