Studysummary 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. Our plain-language summary of this paper — not a Tressless recommendation.
The 2016 study explored the impact of non-ablative fractional erbium glass laser treatment on gene expression in human three-dimensional skin models. The treatment resulted in decreased mRNA levels of matrix metalloproteinases (MMPs) 3 and 9 shortly after treatment, with MMP3 also showing reduced protein levels. However, MMP9 protein levels increased five days post-treatment. The treatment also downregulated inflammatory genes and upregulated epidermal differentiation markers, which was confirmed at the protein level. These findings suggest that erbium glass laser treatment may contribute to dermal remodeling, anti-inflammatory effects, and enhanced epidermal differentiation. The study provides insight into the molecular mechanisms of laser-induced skin effects, although the number of skin models used was not specified.
