Body Contouring — VASER Lipo, BBL & Tummy Tuck

Dr. Sieber is internationally recognised as a pioneer in high-definition body contouring, offering VASER high-definition liposuction, power-assisted liposuction, tummy tuck (mini, traditional, and extended abdominoplasty), Brazilian butt lift with intraoperative ultrasound-guided fat transfer, Renuvion J-Plasma skin tightening, Emsculpt Neo, and Avéli cellulite treatment. He trained in advanced high-definition techniques in Colombia and teaches these methods internationally.

Dr. David Sieber has built an international reputation specifically for aesthetic body contouring, with advanced training in high-definition liposuction under Dr. Alfredo Hoyos and Dr. Humberto Uribe Morelli in Colombia — the originators of the VASER HD technique that produces athletic muscle definition rather than simple fat reduction. He brings this expertise to his San Francisco practice, offering a level of body contouring sophistication that is unusual outside major metropolitan centres. VASER High-Definition Liposuction uses ultrasound energy to selectively emulsify fat while preserving surrounding connective tissue and nerves, enabling precise sculpting of superficial fat planes that create visible muscle definition in the abdomen, chest, arms, and thighs. Standard VASER and power-assisted liposuction (PAL) are offered for patients seeking conventional fat reduction without the HD definition refinement. Treatment areas include the abdomen, flanks, back, arms, inner and outer thighs, knees, neck, and chest. Abdominoplasty (tummy tuck) is available in mini, traditional, and extended variants depending on the extent of skin laxity, diastasis recti (abdominal muscle separation), and the patient's aesthetic goals. Traditional tummy tuck combines rectus muscle plication, circumferential liposuction contouring, and excess skin excision. Recovery involves returning to desk work in one to two weeks, with return to moderate exercise at week four and full activity at six weeks. The Brazilian Butt Lift (BBL) at Sieber Plastic Surgery uses a two-stage approach: liposuction harvest of fat from donor areas followed by intraoperative ultrasound-guided fat transfer to the buttocks — a safety-first technique that confirms fat is placed above the gluteal fascia and away from the deep gluteal vessels, significantly reducing serious complication risk compared to blind injection techniques. Non-surgical body adjuncts include Renuvion J-Plasma for skin tightening (often combined with liposuction), Emsculpt Neo for simultaneous muscle building and fat reduction, and Avéli for targeted cellulite treatment. Patients from across the Bay Area — including Marin County, Silicon Valley, and the East Bay — travel to the Union Square practice for Dr. Sieber's body contouring expertise.
