Laser Hair Removal

Almost everyone has unwanted hair somewhere on their body.

Unfortunately traditional removal routines can be tedious, painful and expensive over time. Shaving may last a day, waxing a couple of weeks, but none of them last
forever — and therein lies the beauty of laser hair removal.

At Nu U Laser Centers we use the Cynosure Elite Aesthetic Workstation with SmartCool 6, the most comprehensive laser hair removal system available today.  It combines two optimal laser hair removal wavelengths into one system; the 755-nm wavelength, which is widely known in the laser industry as the “Alexandrite” or “Alex” laser, and the 1064-nm wavelength, which is known as the “Nd:YAG” or “YAG”  laser.

The “Alexandrite” laser is excellent for light skin, and the “Nd:YAG” is the safest and most effective laser for dark or tanned skin. These are combined with the SmartCool 6, which keeps your skin safe and cool by providing a continuous flow of chilled air during any Cynosure laser treatment.

Because of this, we are able to safely treat a wider variety of skin types. In addition, the system is optimized for effective treatment of facial and leg spider veins, as well as sun and age spots..


Know the difference between Laser and
Intense Pulsed Light (IPL)

Some laser hair removal centers use IPL, which should not be mistaken for laser. IPL devices use a very intense flash of light, like the flash on old cameras. They can be effective for those with light skin and dark hair, but those with darker skin could receive burns if they were to use IPL. (See example)

True laser machines use a single beam of light at specific wavelengths, which makes it safer and effective for a wider range of skin types. The Alexandrite wavelength is the gold standard for light skin, and the Nd:YAG wavelength is the safest for dark or tanned skin.

Here are some differences between the two technologies:
  Laser Intense Pulsed Light (IPL)
Hair Removal (Light Skin) Excellent (Alexandrite) Good
Hair Removal (Dark Skin) Excellent (Nd:YAG) May cause burns
Spider veins Excellent (Nd:YAG) Very Good (Light skin only)
Skin Tightening Very Good (Nd:YAG) Limited
Superficial Pigmentation Excellent (Alexandrite) Excellent (Light skin only)
Deep Pigmentation Excellent (Alexandrite) Limited
Machine Cost $100K and up $25K - $40K


"Many providers who use IPL devices typically market them as lasers despite the fact that they are not, by definition, lasers. Consumers are becoming more aware of these differences and are asking wavelength specific questions during consultations as they understand what they should look for as they shop."

I am not convinced that a 500 watt IPL can outperform a 20,000 watt Alexandrite laser in hair removal as much as I know a Hyundai cannot outperform a BMW.

Q&A

Am I a viable candidate for laser hair removal?
Laser hair removal can be applied to all areas of the body and on all types of skin (even tanned or dark skin).

How does it work?
To eliminate hair, the laser emits gentle pulses of energy that pass through the skin to the hair follicle. This energy is then absorbed into the hair follicle to destroy it so that hair can never grow there again.

Does it hurt?
The treatment causes only minimal discomfort. Patients often say it feels similar to the snap of a rubber band; with the top of the line technology "Cynosure Elite and Smartcool6" this minor discomfort is hardly felt and it is almost pain free. Slight redness or localized swelling can occasionally occur, but this usually subsides within the first 24 hours after treatment.

How many treatments are required?
While only one treatment session is enough to completely treat sun/age spots or veins; multiple treatments are required to get rid of all unwanted hair. Typically, a person with light skin may require 4-6 treatments, and those with dark or tanned skin may require 6-8 treatments.

Once a hair is permanently destroyed by laser, that particular hair may never come back, but different laser settings are needed for coarse hair versus fine hair. Also, in any given area of the body, 10%-30% of the hair there may be in a telogen (resting) phase at any given time. Laser hair removal requires multiple treatment sessions to burn newly formed hairs which were not affected by prior treatments.
