title: 1,450 nm long-pulsed diode laser for nonablative skin rejuvenation.
abstract: BACKGROUND
  There has been growing patient demand for laser technology to treat rhytids and to refine skin texture without the associated lifestyle hindrance common to ablative cutaneous procedures. Nonablative laser systems have been developed to meet this need and, in many instances, have replaced ablative lasers as the preferred treatment modality.
  
  
  OBJECTIVE
  To review long-pulsed diode laser technology in the treatment of a variety of cutaneous disorders.
  
  
  METHODS
  All publications involving 1,450 nm long-pulsed diode laser technology were reviewed and discussed.
  
  
  RESULTS
  The latest generation of nonablative lasers, in the midinfrared electromagnetic spectrum, selectively targets and heats dermal tissue to stimulate collagen remodeling while sparing the epidermis.
  
  
  CONCLUSIONS
  Demonstrating efficacy in the treatment of a wide range of cutaneous disorders, including facial rhytids, acne vulgaris, and atrophic scars, the 1,450 nm diode laser is a useful addition to the nonablative laser armamentarium.
