The Lux2940 is an Erbium:Yttrium-Aluminum-Garnet (Erbium:YAG) laser skin resurfacing laser is a fractionated, ablational laser.  Ablation describes what happens when the laser light contacts the skin.  The light energy is delivered to the water in the skin very rapidly, causing vaporization.  Fractionated means that instead of a solid beam of light, the Lux2940 laser is split up into many tiny microbeams.  This leaves islands of skin that are unaffected by the laser, leading to fast healing of the skin.  This process stimulates collagen production which, in turn, tightens wrinkles and rejuvenates the skin.


What can I expect after treatment?

Immediately after the procedure, there are pinpoint areas of bleeding on the skin.  These areas heal very quickly and in 3 days the skin looks like a bad sunburn.  Over the next 3 to 4 days, the skin continues to heal and you may experience peeling.  There is a moderate burning sensation the night after the procedure that can be lessened with cold compresses.


Most patients take 5 days off from work/school following this procedure.  After 48 hours of healing, the skin will look like a mild to moderate sunburn.  Mineral makeup can be used after 48 hours. The following side effects are expected and typically resolve within 1 week:

  • Redness
  • Swelling
  • Mild discomfort
  • Peeling of skin
  • Small skin cysts (milia)
  • Clear drainage
  • Pinpoint bleeding

When will I see results?

The Lux2940 laser works by stimulating collagen formation in the skin.  The energy from the laser sets in motion a cascade of events that causes collagen to be produced.  However, this occurs rather slowly and the results from treatment won’t start to appear for 3 months.  The best results generally are seen after 6 months.

Where can it be used?

The Lux2940 laser can be used anywhere on the face (except the eyelids). It can also be used for spot treatments on other parts of the body. Lux2940 is used for the following conditions:

  • Mild to moderate wrinkles
  • Sun damage
  • Skin color irregularities
  • Traumatic scars
  • Texture irregularities
  • Acne scars
  • Skin tags/moles


Worsening of acne can occur, but this can usually be treated with topical preparations or a short course of antibiotics.  After the procedure, the skin will be darker than normal.  This is typically transient and resolves over time.  Rarely, the skin can become too light after treatment, which can be permanent.
