ABSTRACT
OBJECTIVES: To assess and compare the efficacy and safety of topical carbon plus short-pulsed and Q-switched Nd-YAG laser to fractional carbon dioxide (CO2 ) laser in improving the appearance of wide facial pores. MATERIALS AND METHODS: Thirty Egyptian patients with wide facial pores were treated in a split-face manner with two sessions of fractional CO2 laser on one side of the face and topical carbon followed by short-pulsed and Q-switched Nd-YAG laser on the other side at 4-week intervals. Clinical evaluation by Investigator Global Assessment (IGA), patient satisfaction level, and photography before treatment and 1 month after the second laser session was performed and adverse effects were monitored. Dermoscopic evaluation by dermoscopy pore score and optical coherence tomography (OCT) evaluation by surface irregularities score were performed at baseline and 1-month posttreatment. RESULTS: One month after treatment, both modalities produced significant reduction in IGA score, dermoscopy pore score, and surface irregularities by OCT (p < 0.001, p < 0.001). Both procedures were well-tolerated. There was no significant difference in IGA, dermoscopy pore score, surface irregularities score by OCT, adverse effects or patient satisfaction level between both treated sides. CONCLUSION: Fractional CO2 laser and topical carbon application followed by short-pulsed and Q-switched Nd-YAG laser can be safely and effectively used to improve the appearance of wide facial pores.

The efficacy of mesotherapy in the treatment of female pattern hair loss (FPHL) has not yet been evaluated. Aim of the study was to compare the initial efficacy and safety of mesotherapy containing nutritional supplements to topical minoxidil 5% solution in FPHL. 30 patients with FPHL were randomly classified into two equal groups: Group A applied minoxidil 5% lotion twice daily; Group B was injected with mesotherapy once weekly. For both groups ultrasound biomicroscopy (UBM) was performed before and at the end of the 12th week of treatment. After treatment, no significant difference was found between both groups with regard to either improvement of hair density and hair loss (P=0.27 and 0.056, respectively), nor the degree of improvement of Ludwig's classification as assessed by the investigator (P=0.210). A significant difference was observed between both groups (P=0.001) with the highest degree of satisfaction in the mesotherapy group. In group A, no significant difference was found in the number of hair follicles or the diameter of the largest hair follicle (P=0.244 and 0.925, respectively). In group B, a significant difference was found in the number of hair follicles (P=0.001), with no significant difference in the diameter of the largest hair follicle (P=0.105). The mesotherapy group showed more improvement with regard to the increase in the number of the hair follicles after treatment (P=0.007). Limitation of the study is small sample size, and relatively short duration of treatment. Mesotherapy, containing nutritional supplements only, is an effective, more acceptable to patients, and more tolerable modality compared with topical minoxidil in the treatment of FPHL.

BACKGROUND: Female pattern hair loss (FPHL) is the most common form of hair loss in women. Nevertheless, its management represents a real challenge. Among the FDA approved therapeutic modalities for FPHL are topical minoxidil and more recently low-level light therapy (LLLT). AIM OF WORK: Assess the efficacy and safety of LLLT in comparison to topical minoxidil 5% and to a combination of both therapies in the treatment of FPHL. PATIENTS AND METHODS: This study included 45 female patients with proven FPHL. They were randomly divided into three equal groups, where group (i) patients were instructed to apply topical minoxidil 5% twice daily, group (ii) patients received LLLT using the helmet iGrow® device for 25 minutes 3 days weekly, and group (iii) patients received a combination of both topical minoxidil 5% twice daily and LLLT for 25 minutes 3 days weekly for 4 months (study duration). Evaluation was done according to clinical, dermoscopic (folliscopic), and ultrasound bio-microscopic (UBM) parameters. Patient satisfaction and side effects were reported. RESULTS: The efficacy and safety of both topical minoxidil and LLLT were highlighted with comparable results in all parameters. The combination group (iii) occupied the top position regarding Ludwig classification and patient satisfaction. UBM and dermoscopic findings showed significant increase in the number of regrowing hair follicles at 4 months in all groups, whereas only UBM showed such significant increase at 2 months in the combination group (iii). A non-significant increase in the hair diameter was also documented in the three groups. CONCLUSION: LLLT is an effective and safe tool with comparable results to minoxidil 5% in the treatment of FPHL. Owing to the significantly better results of combination therapy, its usage is recommended to hasten hair regrowth. Lasers Surg. Med. 49:835-843, 2017. © 2017 Wiley Periodicals, Inc.
