The history of laser treatment traces its origin to May 1960 when laser technology was invented. As early as the mid-1960s, the technology had been used for removing unwanted hairs. After 50 years of this invention, beam lights were inexistent to burn out hair follicles and remove hairs from different areas. Hair removal lasers were first approved by the FDA in 1997.
Initially, the laser hair reduction systems were crude things, which were slow, inefficient, and only suitable for those with light-colored skin with dark hairs. As for patients with darker skin, Ruby-based lasers, with short-wavelength were used for patients having dark skin.
As a result, the treatment would heat up both the hair follicles and the surrounding skin, leading to serious burns. Furthermore, the early lasers targeted a few hair follicles at a given time. With limited capacity, it removing hairs through lasers was no better than other conventional methods.
The Ruby-based systems would often change the color of the treated area and made it either lighter or darker. Therefore, this system had to be discarded. With the advent of the mid-1970s, alexandrite lasers were developed and modified.
These light-based hair removal lasers had more commercial possibilities. Although they were safer as compared to Ruby-based systems, they tended to under-heat hair follicles. This meant that patients had to go through four years of treatment to remove unwanted hair.
With the passing of time, pulsed diode array lasers came into the market. These lasers were marked by long wavelengths and longer pulse duration; making them ideal for people with darker skin. Energy from the lasers was absorbed by the skin pigment, making it more convenient for patients.
The long-pulse YAG laser is the latest development in laser technology for removing unwanted hair. It is often used along with RF energy and is also known as the Laser. This system is majorly used to treat people with dark complexions.
The combination of YAG and RF energy makes it a perfect option for darker skin colors. At present, laser technologies have further improved, leading to improvised techniques and procedures to treat unwanted hair.
There are various high-quality machines and devices that are used for the treatment. The laser treatment clinics are adapting to modern instruments and practices to make the entire treatment comfortable, convenient, and affordable at the same time. With this, patients can hope for better procedures and the best of Full body laser hair removal in Delhi.
