The Best Laser for Hair Removal
By Ahmad Muhajir
Older generation lasers were slow, very painful and worked only on individuals with very dark hair and very light skin. Laser hair removal has come a long way since the first laser hair for removal received FDA clearance in the mid 1990’s. Older generation lasers were slow, very painful and worked only on individuals with very dark hair and very light skin. Today, lasers can work on all skin colors and some lasers are even safe for treating tanned skinned.
1) Is this laser FDA approved for hair removal on my skin type and hair color?
There are several lasers for hair removal available. No one laser is ideal for every individual. Depending on your skin color and hair color, some lasers will be more effective than others.
The Ruby Laser:
This is the "original " hair removal laser. The Alexandrite Laser:
This laser produces reddish light. With its large (up to 18mm) spot size and high repetition rate, the Alexandrite laser is the fastest hair removal laser, and is suitable for rapid treatment of large body areas in patient with light to olive complexion. The Diode Laser:
The long pulse Nd:YAG:
This laser can be used on all skin types, including tanned skin. Large spot sizes and fast repetition rates allow large areas to be treated quickly. Disadvantages include more discomfort during treatment and less effective clearance for fine and light hairs than the other hair removal lasers.
IPL devices are not lasers, because they emit non-coherent light of many different wavelengths. However, because most of the light energy is in the shorter wavelengths, treatment of darker skin types is less effective than with the appropriate laser.
2) What is the spot size of the laser? As spot size increases, a lower percentage of the delivered light energy scatters outside of the treatment area, increasing the depth of pentration, and allowing a lower energy setting to be used for treatment.
3) What type of cooling system is the laser equipped with?
