BACKGROUND/OBJECTIVES: All the standard light-based techniques for permanent hair reduction, like laser and intense pulsed light (IPL) employ the highest tolerable fluence with a single pass. As opposed to standard techniques, a new diode laser technique employs low fluence with multiple passes. Here we evaluate and compare the efficacy, treatment time, comfort and safety of the low fluence multiple pass diode laser with high fluence single pass IPL for permanent hair reduction in Type III to IV Asian patients. METHODS: Thirty Asian patients with Type III to IV black hair were enrolled and received three sessions of treatments at 6-weekly to 8-weekly intervals. A split-leg study was performed in which the IPL was applied to one leg of each patient while the laser was applied to the other. The patients were followed up for 12 months. RESULTS: All patients were satisfied with the results of the long-term hair reduction without long-term side effects. There was no statistically significant difference in hair reduction and treatment time between the laser (76.85%, 21.39 min) and the IPL (74.53%, 22.17 min) (P > 0.05). The visual analogue scale (VAS) pain score of the IPL (5.96) was higher than that of the laser (3.10) (P < 0.01). CONCLUSIONS: A series of high fluence single pass IPL and low fluence multiple pass diode laser treatments were performed with similar efficacy, speed and safety for permanent hair reduction. However, low fluence multiple pass diode laser treatment was less painful than high fluence single pass IPL.

BACKGROUND: Multiple nonablative skin rejuvenation techniques have been used to improve facial aging. OBJECTIVE: To compare rejuvenation efficiency of intense pulsed light (IPL) with nonablative 1,064-nm Q-switched laser in Asian patients. MATERIALS & METHODS: Twelve female subjects were enrolled and received five sessions of treatments at 2-week intervals. A split-face study was performed, with IPL applied to the left side of the face and nonablative 1,064-nm Q-switched laser to the right side. RESULTS: All assessments showed significant skin rejuvenation. For the improvement of skin texture, pore size, and sebum secretion, similar efficiency from laser and IPL was observed. For lightening of skin tone and macula, the IPL was more efficient than the laser after the first treatment, although no further clinical improvement resulted after three treatments. The laser gradually lightened the skin tone and macula and was ultimately more efficient than the IPL after five treatments. CONCLUSION: A series of IPL and nonablative 1,064-nm Q-switched laser treatments were performed with similar efficiency and safety for the improvement in skin texture, pore size, and sebum secretion. IPL was faster, but nonablative 1,064-nm Q-switched laser was more effective in improving skin tone and macula.

OBJECTIVE: To evaluate the hair-removal effect of IPL for hairy skin grafts. METHODS: 10 patients with hairy skin grafts were treated with IPL (ELITEplus) for hair removal 3 to 5 times at intervals of 2 months. The patients received IPL(610 - 1 000 nm) with spot size of 10 mm x 50 mm, pulse width of 5 msec with a delay of 2 - 20 msec, fluence of 30 - 38.3 J/cm2 . RESULTS: The treatment was well tolerated with no need of anesthesia in all the patients. The hairs were removed completely after 3 to 5 treatments. The treated site could be washed as usual with no need of dressing. There was no blister, infection, hyperpigmentation and scarring. Only vellus were existed during the follow-up period of 6 - 12 months. CONCLUSIONS: IPL is a safe and reliable method to remove unwanted hair on skin grafts. It can be easily performed with a lower complication.

OBJECTIVE: To evaluate the hair-removal effect of intense pulsed light (IPL). METHODS: The unwanted hairs were removed with ELITE plus IPL. The treatment took 3 - 5 procedures, with an interval of over 2 months. 341 patients underwent the treatment. RESULTS: All the patients were well tolerant without anesthesia. The unwanted hairs were wholly removed after 3 - 5 procedures. After operation, routine cleaning and make-up were allowed and bandaging was not necessary. There were blister in 3 cases and infection in 1 case. No pigmentation and scarring happened. Following-up of 3 - 6 months showed steady results with less regeneration of very thin and soft hair. CONCLUSIONS: IPL is an ideal hair-removal method because of the credible effect, simple operation, rapid treatment and no serious complications.

OBJECTIVE: To evaluate the collagen changes of allografting an acellular dermal matrix (allo-ADM). METHODS: The allo-ADM was grafted underneath the skin of SD rats. The content of collagen and the proportion of type I to III collagen was examined with a biochemical assay. RESULT: The content of collagen and the proportion of type I to III collagen in the allo-ADM group showed no significant changes. CONCLUSION: The allo-ADM could keep long time in the body and it may be an ideal material for soft tissue filling.
