Theory of Laser Hair Removal:

Rather than a hair by hair approach such as with electrolysis, multiple hairs are treated with each laser pulse. Black- or brown-pigmented hairs absorb laser energy, which is converted to heat, effectively killing the hair follicles. As hair grows in cycles, several treatment sessions are required to achieve long-term hair reduction and possibly permanent hair removal.

As a rule of thumb, people with dark hair and fair skin generally respond very well. The more popular areas being:

  • The underarms
  • Bikini area
  • Arms or legs
  • Back and chest
  • Upper lip
  • Beard area (used for preventing pseudofolliculitis barbae or "razor bumps").

How Lightsheer Duet HIT™ technology works:

Vacuum gently draws skin into the handpiece, skin is stretched thin and target is pulled closer to the energy source.

Energy is applied to target in which melanocytes are spread apart and blood flow is constricted.

Target is damaged and skin is released.

Treatment is usually comfortable and most patients undergoing treatment may feel only a slight pinch sensation with each laser pulse. Areas with a higher density of hair, and certain areas like the bikini can be more sensitive. Numbing cream may be applied one hour prior to the procedure, to reduce any uncomfortable sensation.

After the session:

Some redness and swelling will be experienced around the hair follicles, lasting for a few hours up to a couple of days. Mild scabbing can also sometimes occur, lasting for about two weeks. Do not pick or peel scabs if they occur. Bruising or purpura may be seen over the treatment area that lasts for a few days to 2 weeks. Apply medicated creams as directed, which may be prescribed to ease irritation. In few instances, increases or decreases in pigmentation may occur which will resolve themselves in a few months’ time. Complications, such as blistering, scarring, infections and allergies to applied medications rarely occur.


  • Sun exposure should be avoided for at least one week before and after treatment.
  • Avoid waxing or plucking the hair at the treatment site two to four weeks prior to the laser treatment. Shave or use a depilatory cream instead if necessary. Let some hair grow out prior to the treatment or consultation so that our dermatologist can assess that extent and nature of hair growth.
  • Redness and minor swelling of the treated site may last from a few hours to a couple of days. There may occasionally be areas of scabbing, which last about two weeks. Do not pick or peel scabs if they occur. Bruising or purpura may be seen over the treatment area that lasts for a few days to 2 weeks.
  • No swimming or excessive sweating is recommended after the treatment until all redness subsides.
  • Do not scrub or rub the treated area. Avoid products with alpha or beta hydroxy acids and retinoids when there is redness or scabbing.
  • Not suitable for patients who are pregnant.

Treatment plan:

Lasers only disable hairs that are in their active growing phase. Since hair goes through different growing phases, and approximately 20-85% of hair follicles are in this active growing phase at any given time, several treatments are necessary to disable all hair follicles in a given area. Laser hair treatments provide "long-term hair reduction" and possibly permanent hair removal. The amount of hair will be substantially reduced after 4-8 treatment sessions, at two to three month intervals. Depending on a patient’s ethnic and genetic background, the size of the area to be treated, their skin color, hair color and thickness, 8 or more sessions may be required. Most people are very pleased with results, with a 70-90% improvement in hair density. Any remaining hair is typically much finer and lighter in color, as it is coarse, dark hair that is unsightly and causes problems like ingrown hairs.
