How Dr. Byun Jeik plans treatment

Doje's philosophy — care needs change as time passes — runs through his consultations. He looks first at facial structure, ageing pattern and your own goals, then decides how few interventions will achieve a natural result.

1. Diagnose the layer. Is the change you see caused by skin laxity, fat descent, ligament weakening, volume loss or muscle pull? Each points to a different tool.
2. Combine only as far as needed. Thread lifting, filler, collagen boosters and energy devices are combined selectively. Energy devices are chosen by depth, degree of sagging, fat and elasticity; Doje explicitly avoids applying every device as a package.
3. Use objective data. Mark-View 3D supports skin-quality planning and later comparison.
4. Design to the face. Thread lifts are designed around face shape and the pattern of sagging, with meticulous technique to avoid lumpiness. The clinic states 17 years of accumulated thread-lift experience.

Areas of focus

• Thread lifting (실리프팅) — mid-face, lower face and upper face.
• Soft and structural filler, including retaining-ligament filler.
• Collagen boosters such as Radiesse, and skin boosters.
• Energy-based lifting: Ultherapy Prime, Thermage, Softwave and ONDA.
• Structured programmes: Signature, Mid-Face, Marionette, Jawline, Eye, One-Day, Body and Wedding.
