Core Technology: C.A.T Solution

The **'C.A.T Solution'** (Carving with Adipose Tissues), directly researched and developed by Dr. Sohn You-na, is the greatest competitive edge of Dr. Sonyouna Clinic.

Technical Mechanism & Differentiators

Fat Cell Destruction (Inducing Apoptosis/Necrosis): Unlike general fat-dissolving injections that only reduce cell size, C.A.T Injection destroys the fat cell membrane, reducing cell numbers for semi-permanent effects.
Steroid Free: Formulated with pure enzyme components, C.A.T Injection powerfully markets its absence of steroid-related side effects, a common concern with other contouring injections.
Collagen Synthesis & Lifting: It actively induces collagen synthesis in treated areas, enhancing elasticity and preventing skin sagging, providing a natural lifting effect.

Patent Status (Korea & USA)

The C.A.T Solution's unique formulation ratio and technology have been recognized globally, securing patents in both Korea and the United States.

Patent Content: A patent for the pharmaceutical composition, validating the clinic's unique blend and methodology.
Significance of US Patent: Registered in 2019, the US patent serves as a critical indicator of international verification for the procedure's safety and originality, given the stringent USPTO standards.

Detailed Analysis of Major Procedure Programs

Procedures designed to refine facial contours by targeting unnecessary fat.

V-CAT: The representative procedure that creates a V-line by removing fat from the double chin and jawline. It is also used to tidy up sagging skin after facial contouring surgery.

Lantern Jaw CAT: Adjusts the fat and muscles of the chin tip to correct impressions that look like a protruding chin.

Specialization by Area: Segmented into Arm CAT (including bra line), Abdomen CAT (including love handles), Thigh CAT, Calf CAT, etc.

Reputation and Market Reaction Analysis

Positive Evaluations (Pros)

Safety: For patients concerned about steroid side effects (irregular bleeding, skin depression, etc.), '0% Steroids' acts as the biggest attraction.
Effectiveness: In actual reviews, there is a lot of positive feedback such as "lines were organized without surgery" and "hearing from others that I lost weight." There are many reviews stating that noticeable changes were experienced especially after the 2nd or 3rd session.
Service: Satisfaction with the kindness of the director and staff, luxurious hospital facilities, and systematic reservation system is high.

Negative Evaluations & Considerations (Cons)

Cost: The procedure cost is quite high compared to general factory-type dermatology clinics or low-cost clinics. Even based on event prices, a 3-session Face C.A.T injection package forms around the 2 million KRW range (when discounted), creating a barrier to entry.
Individual Differences: Due to the nature of non-surgical therapy, differences in effectiveness may occur depending on individual constitution, fat amount, and lifestyle habits. Some reviews exist stating that dramatic changes were not felt.
Waiting Time: Due to its fame, it is pointed out that making a reservation is difficult or waiting times may occur even after reservation.
