Background: The reduction in collagen content within the subcutaneous fat layer due to aging results in thinning and weakening of the fibrous septum, leading to an unstable fat pad. Studies on the mechanism of action of polycaprolactone (PCL) collagen stimulators in the adipose layer are lacking.
Objectives: This research aimed to explore the effectiveness of PCL-based filler in enhancing the fibrous septum within adipose tissue, thereby facilitating collagen and elastin synthesis in the adipose layer, while also comparing the disparities in the process between juvenile and aged individuals.
