Clinical Portfolio & Major Procedures

Signature Procedure: 1-Inch Injection

Technique: Utilizes a round cannula (2-3mm) to minimize tissue damage, bruising, and pain.
Target Areas: Applied to abdomen, thighs (inner/outer), arms, and love handles.

Lifting and Anti-Aging

A wide array of energy-based devices (EBD) are used for skin tightening and lifting:

High-End: Ulthera (Ultherapy), Thermage FLX for deep tissue lifting.
Mid-Range/Entry: Popular domestic Korean devices like Shurink Universe (HIFU), LinearZ, Inmode (radiofrequency), and Liftera 2.

Petit Procedures (Injectables)
