The Effects of a 2-W Laser on the Nasolabial Fold of Ageing Individuals Investigated by High-Frequency Ultrasonography: A Nonrandomized Controlled Trial
Abstract:Introduction: Biomechanical qualities of the skin tissue change following numerous pathological and natural (ageing) conditions. The best skin treatments are those resulting in a positive outcome with the fewest adverse effects. In this study, high-frequency ultrasonography (US), which provides a quantifiable scale, was utilized to evaluate the impact of a 2-W laser on characteristics of nasolabial fold (NLF) including depth and area, epidermis and dermis thicknesses, and Young’s modulus (YM). Methods: Nine fe… Show more
