LZR_-1Lasers are an ever growing and changing technology using beams of energy to target unwanted skin conditions. Fractional Ablative and Fractional Non-Ablative resurfacing produces finite columns of treated areas in a gridlike fashion, leaving small islands of normal skin intact to shorten healing time and decrease the risk of pigmentation problems.


  • Reverse Premature photodamage and aging
  • Stimulate and tighten new collagen production
  • Improves texture, pore size, scars, and stretch marks

Non-Ablative lasers treat pore size, fine lines, discoloration, scars, as well as stretch marks. Treatment typically requires 3-5 sessions, but downtime is very limited, with only a few days of mild swelling, and a dry, sandpaper like sensation to the skin. Typically makeup can even be worn to cover this.

Fractional laser treatments are one of the Derm Institute’s specialties. There is no cookie-cutter approach–It is important to take into account skin color and ethnic background to achieve the optimal result. Below is a quickie “Cliff’s Notes” guide on lasers.

  1. There is no magic single laser that treats lzr-2everything, pigment, lines, scars, etc are all different targets that sometimes require different lasers. But Fractionated Non-Ablative Lasers comes close to targeting almost all these concerns to smooth and clear the skin.
  2. Fraxel, Artisan, Pearl, Mixto, etc are all name brands utilizing the same type of non-ablative fractional resurfacing technology with slight variations based on provider preference.
  3. These treatments typically require a few sessions but have minimal downtime of approximately 3-7 days.
  4. The Derm Institute recommends strictly following aftercare instructions, including the application of sunscreen or a healing ointment such as Biafine or Aquaphor to reduce downtime.
  5. IPL or Intense Pulsed Light is not technically a laser, but an intensified light source made to target pigment and blood vessels. Downtime is extremely minimal and great results can be achieved in 1-2 sessions.
