Laser hair removal has come a long way since the first laser for hair removal received FDA clearance in the mid 1990’s.
Older generation lasers were slow, very painful and worked only for 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 and can be performed on any (yes, any) area of the body.
How the Laser Hair Removal Works
The primary principle behind laser hair removal is selective photothermolysis (SPTL), the matching of a specific wavelength of light and pulse duration to obtain optimal effect on a targeted tissue with minimal effect on surrounding tissue. Lasers can cause localized damage by selectively heating dark target matter, melanin, thereby heating up the basal stem cells in the follicle which causes hair growth, the follicle, while not heating the rest of the skin.
Which Laser Hair Removal is Best for Your Skin Tone
Ruby Laser Hair Removal :
This is the “first ” hair removal laser. Its deep red color at 694nm is very well absorbed by the melanin pigment in hair, making it an excellent choice for fine and light hair.
However, because melanin is present in the skin as well, the Ruby laser cannot be used on patients with skin that is not very light, including tanned skin. Because of this limitation, slow repetition rate, and relatively small spot size, Ruby lasers have become less popular for laser hair removal in recent years.
The Alexandrite Laser Hair Removal:
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 . But since its use is only in light skin or olive skin tone it is rarely used in indian skin type.
The Diode Laser Hair Removal:
This laser, consists of a high power laser diode emitting infrared (invisible) light at ~800-808nm. The longer wavelength allows deep penetration into the skin and safety for darker skin types. Now a days diode laser is considered as gold standard for hair removal worldwide.
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. Then disadvantage is less effective clearance for fine and light hairs than some other hair removal lasers.
IPL devices are not lasers, because they emit non-coherent light of many different wavelengths
Advantage of light sheer duet laser hair removal is-
1) Larger spot size, so less time-consuming.
2) Vacuum probe eliminates the requirement of numbing cream.
3) Chill tip technology provides cooling thus protection from the burn.
4) USFDA approved for all skin type.good results in Indian skin tone.
