January 2016 in “Lasers in Medical Science” This study found that non-ablative fractional erbium glass laser treatment affected gene regulation in human skin models by downregulating MMP and interleukin expression, suggesting potential roles in dermal remodeling and anti-inflammatory effects.
In this study, collagen type I, skin fibroblasts, and macrophages did not show remarkable changes in androgenic alopecia patients' scalp tissues after treatment with 1550 nm fractional Er:Glass laser, despite improved hair regrowth.

August 2018 in “Dermatologic Surgery” This study found that 1,550-nm Er:Glass fractional laser treatment increased hair density and shaft diameter in patients with androgenetic alopecia, but did not up-regulate Wnt10A and IGF-1 mRNA expression.
April 2018 in “Journal of Investigative Dermatology” This study found that 1550-nm Er:Glass fractional laser treatment significantly increased hair density and shaft diameter in patients with androgenetic alopecia, though the mechanism may not involve Wnt10A or IGF-1 expression.
