Uses for Non-ablative Laser Rejuvenation

Non-ablative Laser Rejuvenation

What is non-ablative laser rejuvenation?

Non-ablative skin rejuvenation uses a laser to improve the appearance of wrinkles, brown spots and minor scars by creating heat in the skin without injuring the surface of the skin. The heat generated by the laser promotes collagen production which causes the skin to tighten and look young and healthy. Nonablative lasers often are fractionated so they deliver heat into the skin through thousands of tiny, deep columns known as microthermal treatment zones with intervening normal untreated skin. The fractional approach allows the skin to heal much faster than if the entire area was treated. This approach lessens the recovery period and reduces the number of complications that can occur. Multiple sessions are needed in most cases.

  • Cold compresses can be applied to alleviate pain.
  • Sun exposure should be avoided after the treatment. Broad spectrum sunscreens of at least SPF 30 should be applied daily.

What you should know before the procedure

Before the procedure, an ASDS dermatologist will usually review the patient’s medical history and conduct a physical exam. Let your doctor know if you have a history of cold sores or similar disorders. This is also the time for the doctor and patient to discuss appropriate treatment expectations, potential risks and benefits of the procedure. Prior to treatment, the patient should:

  • Avoid tanning or excessive sun exposure.
  • Avoid perfumes, deodorants and other potential irritants in treatment area.
  • Avoid taking aspirin and other blood thinners prior to treatment.
