Nd: YAG laser

What is Nd: YAG laser used for?

Hair Removal

  • Nd:YAG laser may be used for hair removal in any location including underarms, bikini line, face, neck, back, chest and legs.
  • Nd:YAG laser is generally ineffective for light-coloured (blonde/grey) hair, but effective for treating dark (brown/black) hair in patients of Fitzpatrick types I to III, and perhaps light-coloured type IV skin.

The longer-pulse (millisecond) 1064-nm Nd:YAG laser system has been shown to be more effective in safely removinghair than has the Q-switched (nanosecond) Nd:YAG system.

Light pulses target the hair follicle, which causes the hair to fall out and minimises further growth. Typical settings employed include pulse durations of 2 to 20 milliseconds and fluences of 10¬40 J/cm2.


  • Onychomycosis is a common nail disorder caused by fungal pathogens.
  • There are significant barriers to treatment with oral and topical antifungals.
  • Successful treatment of onychomycosis requires antifungal drugs to penetrate the nail plate and nail bed, but this is often incomplete with oral and topical agents.
  •  Laser emit 100–3000 microsecond pulses with an energy fluency of 25.5 J/cm2 for a 1 mm spot size.


Nd:YAG lasers have also be used to improve wrinkles in photo-aged skin.

Are there any side effects from Nd:YAG laser treatment?

Side effects from Nd:YAG laser treatment are usually minor and may include:

  • Pain during treatment (reduced by contact cooling and if necessary, topical anaesthetic)
  • Redness, swelling and itching immediately after the procedure that may last a few days after treatment
  • Rarely, skin pigment may absorb too much light energy and blistering can occur (this settles by itself)
  • Changes in skin pigmentation. Sometimes the pigment cells (melanocytes) can be damaged, leaving darker (hyperpigmentation) or paler (hypopigmentation) patches of skin. Generally, cosmetic lasers will work better on people with lighter rather than darker skin tones
  • Bruising affects up to 10% of patients. It usually fades on its own
  • Bacterial infection. Antibiotics may be prescribed to treat or to prevent wound infection.

How many laser treatments can I expect?

Hair removal

  • In general, patients have 2 to 6 treatments, approximately every 4 to 6 weeks.
  • Patients with darker skin types may require more treatments.


  • In general, patients have 4 treatments at monthly intervals.
