Juvelook® (VAIM, Korea) is made by dissolving irregular PDLLA particles in a solvent mixture of DMSO (Dimethylsulfoxide) and EC (Ethylene Carbonate) and then injecting them through microneedling to create reticulated foamy microspheres, which are hollow spherical particles. It received CE approval in Europe in 2020 and is widely used domestically as a material for tissue restoration, including skin fillers and collagen stimulators. The spherical shape with internal foam structure of PDLLA exhibits excellent biocompatibility, biodegradability, porosity, and mechanical strength. It allows for the control of particle size and acts as a collagen stimulator while gradually dissolving over time. This stimulates fibroblast cells and promotes skin rejuvenation. In clinical practice, Juvelook® particles are injected to address various concerns such as facial wrinkles, increased elasticity, depressed scars, acne scars, accident scars, under-eye hollows, freckles, whitening effects, and neck wrinkles. Therefore, this study aims to investigate the efficacy of Juvelook® not only in volume augmentation but also in improving photoaged skin.
