Laser Hair Removal Surgery – How Does it Work?

Why Hair Removal Laser Surgery?

A treatment by laser produces permanent results relatively quickly. The instant you clear away the curly hair, it’s vanished once and for all, far apart from shaving or threading. Laser treatment can be used to remove age spots and facial hair as well. The laser’s energy turns into heat, thereby destroying the hair follicle but not harming the surrounding tissue. Once a hair follicle is destroyed, it never recovers or grows back. Removing hair with a laser was discovered over 2 decades ago. Since the mid nineteen nineties, laser hair removal surgery has become commercially available. The treatment is becoming wildly popular as of late. Prices are coming down and the technology becomes better.femto lasik in lahore

How Does It Work?

The laser focuses on a tiny little area of tissue that is below the skin. The idea is to heat only the underlying tissue, where the hair follicle is located. The skin tissue on top is never heated. The energy of the laser is absorbed by so-called chromophores. Chromophores are parts of organic molecule that cause it to be colored. The color absorbs the laser’s energy and it is released as heat. Laser hair removal safety is taken very seriously. For this reason, you will have to wear safety eyegear to protect your eyes from the laser. The doctor flashes the laser from a hand-held device for maximum mobility. So many people are in a position to experience it, while there is some irritation. Some people are more sensitive than others. For these people, a local anesthetic is available.

Laser Wavelengths Used To Achieve Results

The laser wavelengths that are used in laser hair removal surgery fall within a certain spectrum. They wavelengths can vary from visible light to radiation that borders on infrared. The wavelength of a laser is determined by the medium used to make them. Laser wavelengths are measured in nanometers (nm). The most common wavelengths used are Nd: YAG: 1064 nm, Pulsed diode array: 810 nm, Alexandrite: 755 nm, Ruby: 694 nm, Argon: 488 or 514.5 nm.

Not only does the wavelength affect the outcome, the length (in time) of the laser pulses also plays a role. For darker skins, longer pulsewidths are advised. Lasers can also have a certain width. The width is also a factor in the end results. You’d believe that the lasers are slim such as a needle, yet are basically as broad in the form of baby’s finger. The width of the laser must be around four times the depth of the target tissue. Yet another important aspect is the energy level of the laser. A laser’s energy level is also called fluence. Then there is the repetition time between the laser shots. Firing two or more pulses at the same target can help heat it up in a way that it causes the least amount of damage to the surround tissue.

What Happens In The Target Tissue?

Laser hair removal surgery works by destroying the hair follicle that produces the unwanted hair. The surrounding tissue may not be harmed. If too much tissue is weakened, you will have accidents that could lead to scar tissue and tenderness. Light is naturally absorbed by dark materials. Hair follicles have plenty of dark chromophores, all round, in and materials them. The laser targets this dark center of the hair follicle and its heat is absorbed by it. Enough heat will eventually destroy the hair follicle. The chromophores that are targeted are either carbon, hemoglobin or melanin.
