Ablative Fractional Lasers Induce Hair Regrowth

In a study published in Lasers in Surgery and Medicine (July 2015), researchers investigated the effect of ablative fractional laser treatments on hair follicle regrowth.

Ablative fractional CO2 laser treatments were administered to the shaved dorsal skin of seven-week-old C57BL/6 mice whose hair was in the telogen stage. Twelve mice were treated at various energy (10 to 40 ...

Ablative Fractional Lasers Induce Hair Regrowth

In a study published in Lasers in Surgery and Medicine (July 2015), researchers investigated the effect of ablative fractional laser treatments on hair follicle regrowth.

Ablative fractional CO2 laser treatments were administered to the shaved dorsal skin of seven-week-old C57BL/6 mice whose hair was in the telogen stage. Twelve mice were treated at various energy (10 to 40 mJ/spot) and density (100 to 400 spots/cm2) settings to determine the proper dosage for maximal effect, then six mice were treated at the decided dosage. Skin samples were obtained via excision biopsy from the dorsal aspect of each mouse, and were used for the immunohistochemistry and reverse transcription polymerase chain reaction assays to examine hair follicle status and their related molecules.

The researchers found that the most effective dosage was 10 mJ/spot and 300 spots/cm2 setting. The anagen conversion of hair was observed in the histopathological examination, while Wnt/β-catenin expression was associated with hair regrowth in the immunohistochemistry and molecular studies. They concluded that ablative fractional lasers appear to be effective for inducing hair regrowth via activation of...

Merz Appoints Two New VPs

Merz North America named David Dobrowski the vice president and head of North American Research and Development, effective immediately. He will be responsible for all medical, regulatory and product safety functions for Merz in North America and will lead the planning and execution of all clinical and pre-clinical development programs.

ASDS Reports Increase in Popularity of Laser Hair Removal

The 2014 American Society for Dermatologic Surgery (ASDS) Survey on Dermatologic Procedures confirms that more patients are seeking laser treatments to permanently remove unwanted hair. About 633,000 laser hair removal procedures were performed by ASDS members last year—a 27% increase from 2013 and a 51% increase from 2012. The ASDS credits the increase in demand to new technologies that have broadened the patient base for laser hair removal. “While the procedure was originally recommended for dark hairs on light skin, newer technologies have made it safer and more effective for patients with a range of complexions and hair colors,” the Society reports

Additionally, the survey showed that ASDS members performed more than 2.7 million procedures using laser, light and energy devices overall in 2014, with the top treatment areas being:

  • Hair removal: 633,000
  • Facial redness: 428,000
  • Photo rejuvenation: 329,000
  • Photodynamic therapy: 311,000
  • Age spots: 224,000

“Lasers and other energy sources have become very good for many indications with minimal downtime and minimal pain associated with the procedures,” said George J. Hruza, MD, president of the ASDS. “Hair removal...
