Long Pulsed Nd: YAG

What is the Long Pulsed Nd: YAG?

The long pulsed Nd; Yag has also been successful in treating common skin conditions. It would also be anticipated that significantly fewer instances of crusting, blistering, pigmentation problems and other adverse epidermal effects would occur with 1064-nm Nd:YAG laser irradiation.

What skin conditions can the
Long Pulsed Nd: YAG treat?

Long pulsed Nd: YAG lasers are being used for treatment many skin conditions such as

  • Warts/ plantar warts,
  • Spider veins,
  • Red Cherry spots,
  • Skin tags
  • DPN – Dermatosis Papulosis Nigrans
  • Seborrheic keratosis (senile warts)
  • Toe fungus ( Onchymycosis)
  • Ingrown hairs or Razor bumps
  • Unwanted hair
  • Unwanted veins

How does the Long Pulsed Nd YAG work?

Laser treatment is based on the principle of photodermal or photomechanical destruction of the target tissue. Target structures ( blood vessels, pigmented lesions) absorb monochromatic coherent light of specific wavelength and fluence. Light energy gets converted to thermal energy, thus destroying the target structure. Depending on the pulse duration and energy density, this may result in the coagulation or blasting of these structures .
When a 1,064-nm long-pulsed Nd:YAG laser is used on the skin, a short, strong laser pulse is absorbed by red structures such as cutaneous blood vessels. As a result, blood vessels heat up rapidly and burst. Upon blood vessel rupture, purpura appear, which subside 5 to 7 days later. This destruction may obliterate the nutrient supply to the wart or destroy the rapidly dividing epidermal cells that contain HPV.
When a 1,064-nm long-pulsed Nd:YAG laser is used on the skin, a short, strong laser pulse is absorbed by raised pigmented structures such as unwanted hair DPN – Dermatosis Papulosis Nigrans or senile warts also known as Seborrheic keratosis .

  • For toe fungus, tiny pulses of light from the laser pass through the toenail to the fungus underneath. The fungus is irradiated without any damage to the surrounding nail or skin.
  • For other conditions such as warts the long pulsed Nd: YAG laser heats up the vascular supply of the lesion in thereby cauterizes the lesion.
  • For pigmented lesions such as DPN and Senile Warts , the melanin is the chromophore which is picked up by the laser to treat the lesion.

How long does the procedure take?

Depending on the condition treated , the treatment will take 10-20 minutes.

How many treatments will I need?

The long pulsed Nd: YAG laser is a quick and painless way to treat the above skin conditions . Depending on the severity of the skin condition, usually 1 to 2 treatment sessions are needed 4 weeks apart.

When will I see results?

Results not noticeable immediately following treatment. For Toe fungus , as your nail grows out, the new nail growth should be clear. Toe nails grow slowly –especially nails infected with fungus. So, it may take 6-12 months for your toenail to clear.
For other conditions , the final result is usually observed after 2 to 4 weeks when the skin has fully healed.

What can be expected after a long
Pulsed Nd: YAG treatment ?

Depending on the condition treated , minimal destruction of the surrounding tissue is anticipated with long-pulsed Nd:YAG lasers. Side effects are generally mild and do not prevent normal activity.

Why would one use the long Pulsed Nd:
YAG to treat common skin conditions ?

Commonly used methods of physical destruction include surgical excision, electrodesiccation, cryosurgery or carbon dioxide laser therapy. Invasive methods have the drawbacks of pain and long recovery periods.

Chemical destruction can be induced with salicylic acid, cantharidin, formaldehyde, or glutaraldehyde, among other agents. Topical management requires the application of drugs for long durations and treatment success is, therefore, highly dependent on patient compliance.

Is the long pulsed Nd YAg FDA approved?

The FDA (Food and Drug Administration) has approved both the long pulsed Nd: YAG laser systems for laser-assisted hair removal in darker skin phototypes. However, irrespective of the type of laser used, multiple treatment sessions are required in order to effectively eliminate the hair. It has been well demonstrated in the past that multiple treatment sessions with the Nd: YAG laser are more effective than a single session

Can the Long Pulsed Nd: YAG laser be used
in ethnic/ dark skin types ?

The development of long-pulsed Nd:YAG lasers, such as the Cutera CoolGlide which have longer pulse durations, has increased the scope of laser hair removal to include all skin types. Difficult to treat razor bumps or PFB can now be successfully treated in black skins as well..

The Long pulsed Nd YAG has have revolutionized our ability to permanently reduce hair growth in dark-skinned individuals with black hair. This new laser combines longer wavelengths with longer pulse durations— the time in which skin is exposed to the laser—and cooling devices to bring down the temperature of the skin following treatment. The longer pulse durations allow more energy to be delivered to the skin, and cooling devices help prevent burning . Micro second Nd YAG lasers can be used safely on black skins as well with no downtime at all.

Is the long Pulsed Nd: YAG available at all
Skin and Body Renewal branches?

Yes, treatments are available in Johannesburg, Sandton, Pretoria and Cape Town Rivonia, Parkhurst, Sandton, Fourways, Irene, Cape Quarter, Claremont, Stellenbosch Willowbridge branches
