1) Infrared laser reduces skin impedance by heating skin and RF energy penetrates deeply into connective tissue to increase the oxygen intracellular diffusion by heating skin. 

2) Vacuum plus specially designed rollers manipulate leads RF penetration to be even 5-15mm. Nip and stretch fibrillar connective tissue greatly improves body contouring effect. Radio Frequency penetrates into the dermal layer of the skin, thus encouraging collagen to regrow so that your skin firms and tightens. 

3) The technology that vacuum folds skin makes RF energy penetrate a specific folded skin, greatly improve effect and safety, even for the upper eyelid area process.
