Double Chin Treatment Non-Surgical Submental Contouring in Korea

Anatomy of the Double Chin

Submental fullness — colloquially called a double chin — arises from three anatomical components: (1) submental fat pad accumulation between the platysma muscle and the dermis, (2) loss of dermal collagen and elastin causing skin laxity in the cervicomental angle, and (3) platysma muscle band relaxation that allows the submental tissue to descend. Genetic predisposition plays a significant role — some individuals develop submental fullness regardless of overall body weight, while others maintain a clean jawline despite higher BMI. Effective non-surgical treatment must diagnose the dominant contributing factor and target it with the appropriate modality.

Deoxycholic Acid: Targeted Adipocyte Destruction

Deoxycholic acid is a naturally occurring bile salt that disrupts adipocyte cell membranes, causing cytolysis and permanent fat cell destruction. When injected directly into the submental fat pad, it selectively destroys fat cells while sparing surrounding tissue. The REFINE-1 and REFINE-2 pivotal trials (Jones et al., 2016) demonstrated that 70.2% of patients achieved clinically meaningful submental fat reduction after 2-4 treatment sessions. At RE:BERRY, the Goop formulation delivers deoxycholic acid in a controlled grid pattern for uniform fat reduction across the submental zone.

Onda Coolwaves: Microwave Lipolysis

Onda Coolwaves (DEKA, Italy) uses 2.45GHz microwave energy — the same frequency absorbed by water molecules — to selectively heat subcutaneous adipose tissue to 55-60 degrees Celsius, inducing adipocyte apoptosis. The Coolwaves handpiece includes an integrated cooling system that protects the epidermis and dermis while energy penetrates to 10-15mm depth. Bacci et al. (2019) demonstrated a mean reduction of 3.2cm in subcutaneous fat thickness in the treated area at 3 months post-treatment. Unlike cryolipolysis, Onda simultaneously stimulates collagen production in the dermal layer, providing a modest skin tightening effect alongside fat reduction.

Multi-Modal Synergy: Why Combination Works Best

RE:BERRY’s Double Chin All-Kill approach (₩1,150,000) combines injection-based fat destruction with energy-based contouring for results superior to any single modality. The injection component (Goop + Berry Slim 10cc each) delivers immediate adipocyte destruction across 3 grid zones. Inmode FX provides fractional RF energy at 1MHz that remodels collagen in the submental dermis, tightening skin that would otherwise sag after fat reduction. Multi-center data from 7 Korean clinics shows combined protocols achieve 85%+ satisfaction rates at 6 months versus 65-70% for single-modality treatments.
