Facial Fat Dissolving Injections: Timeline, Safety, and Results
Facial contouring without surgery has become more achievable than ever, thanks to fat-dissolving injections. Designed to reduce localized facial fat that resists diet and exercise, these minimally invasive treatments help redefine features like the jawline, cheeks, and under-chin area.
But how long does it really take to see results? And what should patients know about the process, timeline, and effectiveness? We spoke with Dr. Do Geon Gi, Medical Director at PlanS Clinic in Seoul, to explore what patients can realistically expect from this increasingly popular treatment.
Fat dissolving injections use deoxycholic acid—a compound naturally found in the body—to break down fat cells in targeted areas. Once disrupted, these cells are metabolized and removed by the body over several weeks.
"It's an excellent option for patients who want subtle yet meaningful changes," says Dr. Do. "It works best in regions like the submental area, where fat is resistant to conventional weight-loss methods."
Unlike surgery, the procedure can be performed in a clinical setting with little downtime. Many patients return to normal activities within a day or two, though temporary swelling or tenderness is common.
Each session typically lasts between 20 to 40 minutes, depending on the number of areas being treated. Most patients report minimal pain thanks to the use of local anesthetics and fine-tipped needles.
Clinical improvements usually begin to appear 3 to 4 weeks after the first session. However, full results typically unfold over 8 to 12 weeks, especially as the body continues to eliminate the broken-down fat.
Dr. Do explains: "Most of our patients require two or three treatments to reach their goals. We space them out about four weeks apart so the body has time to respond."
Individual factors—such as metabolism, skin elasticity, and the specific area being treated—influence the speed and visibility of results. For instance, the under-chin area often responds faster than broader zones like the cheeks.
In some cases, patients with particularly stubborn fat deposits may benefit from up to four sessions. During the consultation, physicians assess the fat layer thickness and skin condition to tailor a strategic treatment plan.
A 32-year-old woman sought treatment for a persistent double chin. Despite regular workouts, the area remained unchanged. After two sessions at PlanS Clinic, she reported a sharper profile and increased self-confidence by week eight.
Her post-treatment feedback highlights improved comfort in photos and social settings. "I finally felt like my jawline matched the rest of my face," she shared.
A 45-year-old man underwent three sessions spaced four weeks apart. His goal: more definition along the lower face. By week twelve, post-treatment images showed significant enhancement in jawline structure, with no surgical downtime.
He noted the convenience of the procedure: "I didn’t need time off work and was back to normal the next day. That made all the difference."
1. Metabolism: Faster metabolisms may process the treated fat more quickly, leading to earlier visible changes.
2. Treatment Area: Smaller zones like the chin often show results sooner than larger regions, where fat density and distribution vary.
3. Session Count: One session may show improvement, but multiple treatments yield more dramatic and lasting outcomes, especially for patients with thicker fat layers.
4. Lifestyle: Diet, hydration, and activity levels can extend or enhance results. Maintaining a stable weight is crucial for preserving the new facial contours.
5. Age & Skin Elasticity: Younger patients tend to experience smoother skin retraction. For older individuals or those with reduced elasticity, complementary treatments like radiofrequency or HIFU (High-Intensity Focused Ultrasound) may be recommended to tighten loose skin.
6. Smoking & Alcohol: Lifestyle habits such as smoking or excessive alcohol consumption may delay healing and impact final results.
Fat dissolving injections are FDA-approved and considered safe when administered by trained professionals. Common side effects include:
Temporary swelling or redness
Mild bruising
Tenderness at injection sites
These side effects typically resolve within 48 to 72 hours. For more sensitive patients, the use of ice packs and anti-inflammatory medications can help manage discomfort.
"We use advanced techniques to minimize discomfort and side effects," says Dr. Do. "Proper post-care and patient guidance are essential for a smooth recovery."
Patients are usually advised to avoid strenuous activity, alcohol, and hot environments such as saunas for 24-48 hours post-treatment.
In rare cases, temporary numbness or uneven texture may occur, but these typically subside over time. Proper technique and anatomical knowledge are key to avoiding complications.
Because deoxycholic acid eliminates fat cells permanently, results can be long-lasting. However, weight gain or poor lifestyle habits may cause new fat to develop.
Some patients opt for touch-up sessions every 12 to 18 months to maintain contour definition. "Think of it like dental hygiene," says Dr. Do. "Ongoing care ensures sustained results."
Long-term studies have shown that with proper lifestyle maintenance, over 85% of patients retain visible improvements for more than two years.
Dr. Do advises periodic reassessment, especially after significant life changes such as pregnancy or major weight shifts. "It’s about maintaining harmony, not chasing perfection," he adds.
PlanS Clinic stands at the forefront of non-invasive facial sculpting in Asia. With over 25,000 satisfied patients, the clinic combines experience, innovation, and a commitment to patient safety.
Dr. Do Geon Gi, a board-certified aesthetic physician, developed the proprietary PPE Injection protocol—a refined method of targeted fat reduction designed to maximize results while preserving natural facial harmony.
This technique includes precise dosing, strategic injection patterns, and a layered approach to fat elimination and skin support. It is especially beneficial for patients seeking natural results without a "hollowed" appearance.
Patients receive custom treatment plans, imaging consultations, and close follow-up to track progress and make any needed adjustments. The clinic also offers combination therapies with microneedling, skin tightening, and regenerative boosters for holistic facial rejuvenation.
A: Most patients return the next day, though minor swelling may persist for a few days. If desired, makeup can be used to conceal any bruising.
A: Some mild discomfort is normal. We use numbing agents and cooling to ensure a tolerable experience. Most patients rate the discomfort as 2 to 3 out of 10.
A: Yes, it's often paired with skin tightening, microneedling, or laser therapies. Combining treatments can enhance overall facial symmetry and skin quality.
A: We adjust the treatment plan and often recommend an additional session. Patient satisfaction is tracked through photographic progress and periodic evaluations.
A: Yes—eliminated fat cells don't return. However, new fat can form with significant weight gain. Maintenance and a healthy lifestyle are key.
Facial fat dissolving injections offer a powerful, non-surgical path to enhancing your features with minimal disruption. With a tailored approach and expert oversight, patients can achieve long-lasting, natural-looking improvements.
