Skin Tightening Effect Using Fractional Laser Treatment: I. A Randomized Half-Side Pilot Study on Faces of Patients with Acne

DERMATOLOGIC SURGERY, Issue 1 2010
TERUKI DAINICHI MD
BACKGROUND Fractional laser resurfacing is a new procedure for skin rejuvenation. OBJECTIVE To assess the skin remodeling effect of fractional laser treatment. METHODS Twelve Asian patients with acne were irradiated using a fractional 1,540-nm erbium glass laser on a random half of the face twice with a 4-week interval. RESULTS The faces were contoured on the treated side of most patients. Statistical analyses of the facial images showed that the skin tightening effect was significant 4 weeks after the first and second irradiation (p<.001 after both treatments). CONCLUSION These results suggest that fractional laser resurfacing is a possible alternative to nonsurgical skin tightening of the face. The authors have indicated no significant interest with commercial supporters. [source]

Eyelid Tightening and Improved Eyelid Aperture through Nonablative Fractional Resurfacing

DERMATOLOGIC SURGERY, Issue 11 2008
SEAN A. SUKAL MD
BACKGROUND AND OBJECTIVE The effects of fractional resurfacing on eyelid tightening and aperture are unknown. Our purpose was to retrospectively examine the potential for eyelid tightening and eye-aperture opening in patients treated with nonablative fractional resurfacing for facial photorejuvenation. STUDY DESIGN/MATERIALS AND METHODS Fractional laser treatments using a 1,550-nm erbium-doped fiber laser system on the upper and lower eyelids were given at a pulse energy of 17 to 20 mJ at 125 micro-thermal zones (MTZ)/cm2 to a final density of 500 to 750 MTZ/cm2. Each patient had 3 to 7 treatments. Standard pre- and post-treatment photographs were taken at each visit. Physicians who graded 31 preselected patient photographs using a 4-point scale evaluated eyelid tightening. Increase in eyelid aperture was also evaluated. RESULTS All patients had some degree of eyelid tightening; 19% achieved 1% to 25% tightening, 26% achieved 25% to 50%, 26% achieved 50% to 75%, and 29% achieved 75% to 100%. Increase in eyelid aperture was seen in 55.9% of patients. Postoperative wounding, hypopigmentation, hyperpigmentation, persistent erythema, and scarring were not observed. All patients experienced mild or no edema for a few days after treatment. CONCLUSION Fractional resurfacing tightens and increases eyelid aperture without wounding, downtime, or long-term complications. [source]

Improvement of Postfractional Laser Erythema with Light-Emitting Diode Photomodulation

DERMATOLOGIC SURGERY, Issue 5 2009
TINA S. ALSTER MD
BACKGROUND The most common side effects of fractional laser skin treatment are erythema and edema. Low-level light therapy and light-emitting diode (LED) devices have been used to stimulate fibroblast activity and hasten wound healing. OBJECTIVE To determine whether LED treatment immediately after fractional laser skin resurfacing affects the severity and duration of postoperative eythema. MATERIALS AND METHODS Twenty patients received treatment with a 590-nm wavelength LED array to randomly selected facial halves immediately after undergoing full-face fractional laser skin resurfacing with a 1,550-nm erbium-doped fiber laser. Differences in erythema between LED-treated and untreated facial halves were recorded at 24, 48, and 96 hours post-treatment. RESULTS The LED-treated facial halves were less erythematous in all 20 patients 24 hours postoperatively. The six patients who received the highest mean energy densities during fractional laser treatment continued to exhibit decreased erythema in the LED-treated areas at 48 hours. At 96 hours post-treatment, no discernible differences between facial halves were observed in any patient. CONCLUSIONS Photomodulation with a 590-nm-wavelength LED array can decrease the intensity and duration of postfractional laser treatment erythema. [source]

Comparison of clinical outcome parameters, the Patient Benefit Index (PBI-k) and patient satisfaction after ablative fractional laser treatment of peri-orbital rhytides,

LASERS IN SURGERY AND MEDICINE, Issue 3 2010

Abstract Background Laser treatment of facial rhytides has evolved as a major modality of aesthetic surgery. Published results, while generally encouraging, feature highly diverse evaluation methods, which makes an evidence-based assessment of treatment efficacy and safety all but impossible. Objective To compare the results of different instruments of measurement. Patients/Methods Twenty-eight patients were enrolled and completed the entire study. They received a single ablative fractional treatment of the peri-orbital region. The evaluation included the Fitzpatrick wrinkle score, the profilometric measurement of wrinkle depth and the Patient Benefit Index (both before and 3 months after treatment) as well as the assessment of patient satisfaction (1, 3, 6 days and 3 months after treatment). Results All assessment instruments showed a significant, albeit moderate, improvement. The agreement between assessment methods was poor. Despite claiming to assess basically the same parameter, the Fitzpatrick wrinkle score and profilometry differed significantly, and neither assessment instrument showed any appreciable correlation with any other. Conclusions The outcome assessment of rhytide therapy,regardless of the method used,shows substantial room for improvement. Strict methodological precautions ought to be applied for ,objective' evaluation methods like photographic scoring and profilometry. Subjective methods of assessment are essential and might serve as a main outcome parameter. Finally, critical reappraisal of published treatment results seems warranted to review the quality of their methodology. Lasers Surg. Med. 42:215,223, 2010. © 2010 Wiley-Liss, Inc. [source]
