“…There are still up to date studies that present results after short periods of 3 months or 6 months such as studies intended to compare different treatment conditions and treatment parameters. However, hair removal evidence which includes long‐term follow‐up period of 12 months is considered more convincing as it indicates long‐term results sustainability.…”

“…A wide variety of studies were conducted and published over the last twenty years, evaluating long‐pulse 810 nm diode lasers showing long‐term hair removal results with minimal transient side effects. More recent articles focused on studies comparing adjustable treatment parameters such as fluence, repetition rate, number of passes, movement modes or spot size in order to optimize results and reduce treatment discomfort as well as different skin conditions …”

Summary Introduction Laser hair removal is a common light‐based aesthetic procedure. Diode lasers and specifically the long‐pulse diode laser 810 nm are the most popular preference for hair removal due to the deep penetration and targeting of the hair follicle. In a recently published article, we presented our hair removal clinical evaluation results using an 810 nm scanning diode laser. Three‐ and six‐month follow‐up hair counts demonstrated an average hair reduction of about 70%. Objective In the current article, we demonstrate long‐term follow‐up hair removal results of 1 year after last treatment. Methods Among 11 out of 14 female patients who received three axillary hair removal treatments, 4‐6 weeks apart, returned to the 1‐year follow‐up visit. Treatment area photographs and hair count of 1‐year follow‐up visit were compared to baseline. Results The average hair count reduction of about 70% at 1 year after the last treatment was maintained. Conclusions The examined 810 nm diode laser has been proven to be a safe and effective for hair removal. Results sustain not only for 3 or 6 months but also for 1 year after last treatment.

Summary Technical advances in recent years have led to new dermatologic laser systems, light sources, and treatment concepts. Commonly used wavelengths – generated today with LED‐based devices – allow for the combination of various tissue effects and are associated with improved outcomes. Laser hair removal has become more efficient with the use of diode lasers that emit multiple wavelengths simultaneously. In the near future, novel LED‐based lasers will also be introduced for the treatment of vascular lesions. Here, too, the combination of different wavelengths promises to be beneficial. Picosecond lasers have led to advances in the field of pigment removal (tattoos).

“…12 Many studies have been reported about relationship of fluence, repetition rate and treatment effectiveness. Li et al 13 compared the safety and efficacy of different fluencies and repetition rates of using the 810 nm diode laser for axillary hair removal. It was concluded that a low fluence (10 J/cm 2 ), high repetition rate (10 Hz) mode is more efficient method of laser hair removal with less treatment discomfort than high fluence (34-38 J/cm 2 ), low repetition rate (10 Hz).…”

Prospective, Comparative Evaluation of Forearm and Lower Leg Hair Removal with 808-nm Diode Laser at Different Fluences

Background and Objectives High fluence diode lasers have emerged as the gold standard for removal of unwanted hair. Lowering the energy should result in less pain but could theoretically affect the efficacy of the therapy. The author designed this study to compare the efficacy of a low fluence 808-nm diode laser to that of a high fluence 808-nm diode laser for permanent hair removal in Korean women. Materials and Methods The author classified 26 Korean women into 2 groups. The groups received laser treatment for either the forearm or the lower leg using a low fluence HR808 prototype diode laser on one side and a high fluence laser on the other side at 1-month intervals. Hair counts and thickness were recorded by folliscope and photograph at each follow-up visit and at the 3-month follow-up after the final laser treatment. At the final visit, patients were surveyed regarding pain and satisfaction. Three plastic surgeons assessed the results by photograph. Results In the forearm group, the median reduction of hair density was 14.4% with low fluence and 19.0% with high fluence. The hair thickness reduction rate was 50% with low fluence and 65.6% with high fluence. Pain scores were 1.91 and 2.1, respectively. In the lower leg group, the median reduction of hair density was 45.9% with low fluence and 63.7% with high fluence. The hair thickness reduction rate was 57.7% with low fluence and 60.7% with high fluence. Pain scores were 2 and 2.4, respectively. Conclusion High fluence HR808 prototype diode laser can efficiently remove unwanted hair. In terms of treatment comfort, there was no significant difference compared to low fluence mode.
