The double chin (submental fat accumulation) is a common concern across all age groups. Even at normal weight, genetic factors, skin laxity, and fat accumulation can cause submental fullness that blurs the side profile. Seoul’s Rappoel Dermatology uses APTOS thread lift technology, implanting absorbable threads in the submental area to physically lift sagging tissue and stimulate collagen production — reshaping a clear chin contour without surgery.
Causes of Double Chin Formation
- Genetics: Naturally larger submental fat pads cause double chin even at low body weight
- Fat Accumulation: Weight gain leads to fat deposition in the submental area
- Skin Laxity: Age-related loss of submental skin elasticity causes tissue descent, forming “pseudo-double chin”
- Skeletal Factors: Retrognathia (recessed chin) lacks bone support, making soft tissue accumulation more visible
- Poor Posture: Chronic phone-down posture weakens neck muscles, worsening double chin appearance
APTOS Thread Lift Technique
- Pre-Treatment Design: The physician assesses submental fat volume, skin laxity, and chin bone position, marking thread insertion paths
- Anesthesia: Local anesthesia, no general anesthesia required
- Thread Selection: APTOS bidirectional barbed absorbable threads (PLA/PGA material) providing bidirectional lifting force
- Insertion Technique: Threads inserted from both sides of the submental area, running along the inner mandibular border toward the midline, forming a mesh support structure
- Thread Count: Typically 6-10 threads, adjusted based on submental area and laxity degree
- Total Time: Approximately 30-45 minutes
- Duration: Threads absorb in 6-8 months; collagen stimulation effects last 12-18 months
Combined Effects of Thread Lift
- Clear Contour: Submental tissue is lifted upward, creating a smooth line from chin to neck
- Fat Compression: Thread pressure compresses and reshapes the submental fat pad
- Skin Tightening: Threads stimulate collagen production, improving submental skin elasticity
- Chin Enhancement: After lifting, chin contour becomes more defined, improving side profile proportions
- No Surgery: Only pinhole-sized incisions, short recovery time
Suitable and Unsuitable Candidates
Suitable: Mild to moderate double chin, skin laxity-type double chin, those preferring non-surgical options, those who tried ONDA fat reduction and need further tightening.
Unsuitable: Severe fat accumulation (ONDA first recommended), severe skin laxity (surgery recommended), severe chin recession (chin filler or implant recommended).
APTOS thread lift for double chin is an effective minimally invasive contouring option, but requires the physician to precisely control implantation depth and thread tension. Superficial placement may cause visible threads or skin irregularities, while excessive tension may cause discomfort. Rappoel Clinic is located 3 minutes from Gangnam Station Exit 10, holds APTOS official certification, and uses authentic APTOS threads.
