Optical fiber liposuction technology is a very good method, which has the advantages of less damage and quick recovery. It can shrink loose skin while liposuction, and there will be no unevenness caused by negative pressure liposuction.

Moreover, it has proper illumination to skin tissue, stimulates the proliferation of fibroblasts, tightens loose skin and eliminates wrinkles.
