Our objective is to assess the efficacy and safety of a protocol using intense pulsed light (BBL; Sciton Inc., Palo Alto, CA) to improve the appearance of senile purpura on subjects' extensor forearms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Study Design\/Materials and Methods<\/jats:title>\n                    <jats:p>Five subjects over 65 years of age, with ecchymotic lesions measuring over 1\u2009cm on each forearm and five younger subjects under 35 years of age, without any ecchymotic lesions, were included in the study. The subjects were treated on one randomized forearm with a new intense pulsed light protocol for four weekly sessions. Photographs and subject questionnaires were taken weekly before each treatment as well as 1 month after all treatments. Skin biopsies were taken 1 day after the last of four weekly treatments. Histological analysis, including hematoxylin and eosin, elastic van Gieson, and Masson's Trichrome staining, were carried out to assess both the epidermal thickness and dermal connective tissue structure.<\/jats:p>\n                    <jats:p>The protocol consists of multiple passes using an intense pulsed light (BBL; Sciton Inc.) device in which the wavelength, filter, and fluence are adjusted for each step. Step 1 uses infrared light (800\u20131,400\u2009nm), high intensity, a smooth adapter, and a constant motion technique. Step 2 employs a 590\u2010nm filter with two different fluences and step 3 utilizes a 560\u2010nm filter. The fluence of steps 2\u20133 is increased by 1\u2009J each treatment if no side effects are noted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Using a new intense pulsed light protocol in subjects with senile purpura, both the number and square area of ecchymoses on the treated arm were significantly reduced (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.02 and\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.04, respectively, paired\n                      <jats:italic>t<\/jats:italic>\n                      test) as compared with the untreated arm at 1 month after four weekly treatments. Despite this pilot study including challenging cases of subjects on both inhaled and injected corticosteroids and blood thinners, all subjects with senile purpura had at least a 50% reduction in the total square area of their ecchymoses on their treated arm. There were no significant or long\u2010lasting side effects, and all subjects reported satisfaction with the treatment with a desire to continue treatments on their control arm.\n                    <\/jats:p>\n                    <jats:p>\n                      Blinded evaluators were able to select 100% of the time in the subjects with senile purpura, which was the treated arm as compared with the control arm when reviewing photographs from 1 month after the last treatment. In addition, several subjects were noted to have a significant improvement in the appearance of hemosiderin deposition and photodamage. Histologically, intense pulsed light treatments significantly increased epidermal thickness in elderly subjects by 21.14% (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.0153, two\u2010tailed, paired\n                      <jats:italic>t<\/jats:italic>\n                      test), to levels comparable with young subjects. Such restoration is consistent with the other histological observations by blinded evaluators of more abundant and organized collagen fibers in the dermis and reduced aggregates of disorganized elastin fibers.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This new intense pulsed light protocol is safe and effective in improving the clinical appearance of senile purpura as well as preventing future lesions by improving the structure of the skin by increasing epidermal thickness and improving collagen and elastic fiber morphology. The treatment was well\u2010tolerated, adverse effects were minimal, and there was high patient satisfaction. Lasers Surg.
