About

This is a single-center, open-label pilot study to determine the effect of large area fractional laser treatment (LAFLT) on adults' metabolic profile.

Full description

The current research project aims to investigate the effects of large-area fractional laser treatment (LAFLT) on body weight, metabolism, and body composition. Prior research suggests that treating large skin areas with fractional laser therapy may stimulate metabolism and promote weight loss. The MIRIA laser, an FDA-approved fractional laser, is widely used for skin aging, acne scarring, and wrinkle reduction and will be used to evaluate these potential metabolic effects.

Subjects aged 18-60 with a BMI of 25-30 will undergo three fractional laser treatments on the abdomen and thighs over 36 weeks, with sessions every four weeks. The study includes six total visits, incorporating photography, non-invasive imaging, x-rays, blood draws, and two optional biopsies.
