3 Different Laser Types Used for Hair Removal
Every Laser Hair Removal treatment is done under supervision of a Dermatologist. Consult our Dermatologist now
At Care Well Laser, Skin & Anti Aging Clinic we have 3 different types of lasers. Type of laser to be used for any individual completely depends upon his/her skin tone, hair density & thickness of hair.
Laser procedures are one of the most effective hair removal techniques available in the market. It has shown proven results with almost all the patients taking this treatment. There are however three variations of this procedure for different skin types:
Wavelength: 810 nm
Effective on: Medium skin tone
Less effective on: Comparatively less effective on finer, lighter hair
Wavelength: 755 nm
Effective on: White skin tones and is also known to be effective on finer, thinner hairs in comparison to other lasers
ND Yag Laser
Wavelength: 1064 nm
Effective on: Works on almost all skin types including tanned or darker skin tones
Less effective on: Light or fine hair, when compared to other lasers
Diode Laser (810 nm) is best for medium skin tone Diode Laser is very effective. It is comparatively less effective on finer, lighter hair.
This is a Laser procedure performed on dark-skinned patients. This procedure does not work on light toned hair. It can be repeated in shorter durations and is usually used for treating large body regions.
The Diode Laser is longer in wavelength and thus gives a better result on dark toned skin and hair. It has a safer result and a deeper skin penetration. The recovery of this procedure is also faster. This procedure involves a beam of concentrated light and heat targeted at the follicles of the hair. The melanin pigment absorbs it and gets destroyed by the laser beam without affecting the skin. This procedure is however slightly more painful than the others.
The side effects associated with this hair removal procedure is minimal and transient. There can be limited scarring and red spots post treatment. This is due to the burning of the hair follicles and will wear off in a day or two. However, some patients show signs of hives or urticaria, a kind of rash which is a result of adverse reaction to the skin post treatment. There are no major side effects observed in this procedure. According to a research this procedure gives maximum hair thinning within first two treatments. It is however necessary that the skin is cooled pre and post treatment to minimize the scarring and bruising.
Alexandrite Laser (755 nm) is effective on white skin tones and is also known to be effective on finer, thinner hairs in comparison to other lasers.
This is the second type of laser procedure which is effective in almost all the skin types and basically uses a high energy beam of 755nm which is red in color. The procedure involves the laser beam passing through an Alexandrite crystal which creates an energy beam of the said wavelength. It is the more frequently used form of laser for hair removal. The laser beam thus passed, is absorbed by the melanin in the skin more effectively thus giving a more effective result. The major advantage of this process is its time consumption. This procedure applies the principle of selective photothermolysis, or the technique used to target specific tissue by matching wavelength and heating the tissue to destroy it completely.
This is a faster way of treating larger areas at a very less time with better results. However, the laser pulses are more rapid at quicker duration which leads to more pain and discomfort to the patient. The results are more permanent with minimal or no re-growth. The hair which grows back is also lighter and less thick than before. This treatment is effective on thin and fine hairs also which can't be treated with the other techniques. This technique also requires cooling of the surrounding skin area to minimize chances of bruising and scarring.
Other areas where this can be used are- in treatment of age spots, spider veins, birthmarks of vascular nature, and in tattoo removal.
ND Yag Laser
Nd Yag Laser (1064 nm) works on almost all skin types including tanned or darker skin tones & is less effective for light or fine hair, when compared to other lasers.
This is the third kind of laser procedure. Here, the "Nd" means Neodymium, and "YAG" yttrium aluminum garnet. This can be used to treat skin of all types including tanned. However, there is an increased effectiveness observed on dark and tanned skin unlike the other laser techniques which work best on lighter skin tones. This is due to its deeper penetration and reduced scatter.
This treatment uses laser beams of higher wavelengths (1064nm) to target the hair follicles and destroy the without much damage to the surrounding skin region. In this, the skin is treated with carbon lotion to let it penetrate the hair follicles. When the laser beam is discharged, the follicle absorbs it and gets destroyed. This procedure also advocates cooling of the area to be treated so as to ensure that the heat does not burn or bruise the surrounding skin. Like the Alexandrite technique, this treatment can also be advocated at shorter frequencies to give better results in a short time span. This technique allows the laser beam to take a longer time to be delivered in a longer time span enabling the heat generated to dissipate thus reducing epidermal bruising. This procedure is also effective on lighter tones of hair which are finer in nature thus ensuring a better result. The other treatments done with this laser is tattoo removal and hyperpimentation or the botchy and irregular skin tone.
This procedure is more effective at the same time more painful. The effects of bruising are reduced due to the heat dissipation.
