Clinical Improvement of Photodamaged Skin After a Single Intense Pulsed Light Treatment

摘要

Background and Objectives: Photoaging is clinically characterized by irregular pigmentation (freckling, lenti-gines, persistent hyperpigmentation), drynesslroughness, telangiectasia, wrinkling, elastosis, and inelasticity. Currently available medical literature documents using intense pulsed light (IPL) 3 to 5 times to achieve satisfactory improvement.Study Design/Materials and Methods: Twenty patients of Fitzpatrick skin types I-III, each with components of photodamaged skin including telangiectasias, dyschromia, skin roughness, enlarged pore size, and/or rhytides-participated in the study and were treated with a single Lumenis One IPL. Pretreatment and posttreatment photographs were graded by 2 independent physicians as to percent improvement.Results: After I treatment with the Lumenis One IPL, results showed an average improvement of 40% in resolving telangiectasias, dyspigmentation, and fine wrinkling.Conclusions: The present study demonstrates that as much as a 40% improvement in the overall appearance of photoaging can be obtained after a single treatment with the Lumenis One IPL. Previous studies with IPL using the Lumenis Photoderm, Vasculite, or Quantum systems found that 3 to 5 treatments were needed to obtain a similar improvement. These IPL systems have a smaller spot size, a different energy output profile, and a cutaneous cooling mechanism that may explain their decreased efficacy compared with the Lumenis One.
