Understanding Laser Hair Removal: Alexandrite, Diode, and Yag
Many people experience great results from laser hair removal. First practiced in 1961, laser is now one of the most common cosmetic procedures in the United States. It is FDA-approved with mild or no side effects. In this article, we will briefly discuss laser hair treatments in general and outline the three primary laser options: Alexandrite, Diode, and Yag.
Did you know that laser is actually an acronym for “Light Amplification by Stimulated Emission of Radiation”? The process of laser hair removal works due to a wavelength of strong energy light being emitted into hair follicles. The pigment in the follicles absorbs the light, which causes the hairs to be destroyed. Laser causes hair to fall out and prevents additional growth. The feeling of laser hair removal is often compared to the snapping of a rubber band onto the skin. Laser can be applied almost anywhere on the body, including the underarms, face, neck, back, chest, bikini line, and legs. Generally, people who benefit most from laser treatments are light-skinned with dark hair.
Alexandrite Laser
The first method, Alexandrite, uses an alexandrite crystal as the laser source. This laser creates a short wavelength of light in the infrared spectrum at 755 nm, which means it is a red light laser. This method is often considered the gold standard of lasers.
The Alexandrite laser works by emitting strong light energy and converting it to heat energy, a process known as photothermolysis (using light to heat for destruction). These lasers are extremely thorough and work quickly. They damage hairs in a very specific area on the body while leaving surrounding tissue unaffected.
The Alexandrite laser treats more than just unwanted hair. It addresses a variety of skin issues, such as spider veins and vascular birthmarks. It even aids in tattoo removal. Only people with very light to olive-colored complexions should use this method. It can cause some pain and is suited for large areas.
Diode Laser
The next method is the Diode laser, one of the newest forms of laser hair removal. It is known as an infrared light, operating at an 800 or 810 nm wavelength, slightly longer than the Alexandrite. This longer wavelength allows the light to penetrate deeper into the skin’s epidermis, making the process safer by preventing melanin pigment formation.
People with either light or darker skin tones find success with Diode, and it serves best as a short-term treatment. It is somewhat painful and is suited for smaller areas.
Yag Laser
The final method is the Yag laser, which operates at a 1064 nm wavelength. It works fairly fast and can treat all skin colors but works best on the darkest skin. It can even treat tanned skin. This method is ideal for short-term treatment. The Yag laser is relatively painful compared to the others and is suited for large areas.
Choosing Between Laser and Electrolysis
When it comes to choosing between laser or electrolysis, it is important to note that laser may work faster, but it is not a permanent method. Electrolysis is the only permanent method of hair removal approved by the FDA. Laser may give you temporary results or work long-term depending on your skin type and treatment schedule. Electrolysis treats a single hair follicle at a time, while lasers treat multiple hairs per laser pulse. Anyone can use electrolysis regardless of skin color or hair type, while laser typically works best on lighter skin.
Sometimes it is a good option to do several laser treatments before beginning electrolysis. For example, if you are looking to have the hair on the back of your neck removed, having the area treated with a laser first for three to four sessions will speed up the process of electrolysis and can be more effective. This is something that can be discussed on a case-by-case basis, and factors such as which part of the body and client’s genetics will be taken into consideration.
