Belkyra – How Long to See Results?

May 14, 2025

Did you know that the number of fat cells in your body remains relatively constant throughout adulthood? While fat cells can expand or shrink with changes in weight, their overall number doesn’t decrease significantly. This explains why stubborn fat deposits—especially under the chin—can be difficult to eliminate with diet and exercise alone.

Belkyra, an FDA-approved injectable treatment, provides a non-surgical solution for reducing submental fat (fat beneath the chin). By breaking down fat cells, it offers a gradual yet permanent reduction in volume. Though individual results may vary, most patients notice improvements within weeks, with optimal results typically seen after several treatment sessions.

In this article, we’ll explore how Belkyra works, what the expected timeline for results looks like, and what patients can anticipate throughout the treatment process.

Key Takeaways

  • Belkyra provides a nonsurgical injectable treatment that actively reduces submental fat (double chin) by using synthetic deoxycholic acid to break down fat cells.
  • Most patients require 2 to 4 sessions, spaced 4 to 6 weeks apart, to achieve optimal results. Sessions last 15–30 minutes and are minimally invasive.
  • Swelling, tenderness, and bruising are common side effects, usually resolving within a few days to two weeks.
  • Visible improvements typically begin around the 4 to 6-week mark, with full results appearing in 12 weeks after the final session.
  • Belkyra permanently destroys fat cells in the treated area, and results last as long as patients maintain a stable weight.
  • Ideal candidates are adults with moderate submental fat, good skin elasticity, and realistic expectations for gradual contour improvement.
  • Before-and-after photos and patient satisfaction confirm Belkyra’s effectiveness in achieving a more defined jawline and improved facial contours.

Treatment Protocol – Understanding the Belkyra Process

Belkyra (deoxycholic acid) treatments are generally performed in multiple sessions to achieve the desired contouring results. On average, patients undergo 2 to 4 sessions, although some may require up to 6 sessions depending on the amount of submental fat and individual response to treatment. Each session consists of a series of small injections into the target area under the chin.

Practitioners space sessions about 4 to 6 weeks apart to allow the body time to break down and absorb the destroyed fat cells between treatments. This interval also allows for a reduction in inflammation before the next session begins. Adhering to this schedule is crucial for obtaining consistent, optimal results. Providers customize each treatment plan based on factors like fat volume and patient goals, ensuring that the treatment is both safe and effective.

Physiological Response – What Happens Post-Injection

The active ingredient in Belkyra, deoxycholic acid, is a naturally occurring molecule in the body that helps break down and absorb dietary fat. When injected into submental fat, the acid disrupts fat cell membranes, effectively causing them to rupture and release fat.

After treatment, the immune system recognizes the destroyed fat cells as waste and eliminates them through metabolic processes. This natural response typically takes several weeks, explaining the delay in visible results. Patients typically experience swelling, firmness, and inflammation in the treated area—expected reactions that indicate the treatment is working. Over time, the treated area will show more defined contours as the fat volume decreases.

Patient Experience – Managing Expectations and Side Effects

Most patients experience swelling, tenderness, and bruising immediately following their procedures like the Belkyra double chin treatment. Swelling is often the most prominent side effect and can last anywhere from a few days to two weeks. Mild discomfort, numbness, and firmness under the chin are also typical and should subside naturally.

To help manage these temporary side effects, patients can:

  • Apply cold compresses to the treated area for 10–15 minutes within the first 24–48 hours.
  • Avoid strenuous activities for 48 hours after the session to minimize swelling.
  • Sleep with your head elevated to help reduce swelling overnight.
  • Use over-the-counter pain relievers, as recommended by the provider.

Patients should prepare for early swelling, which may temporarily make the area appear fuller before the actual results become visible. Setting proper expectations can help patients manage this initial phase and reduce post-treatment anxiety.

Monitoring Progress – Assessing Belkyra Treatment Outcomes

Tracking progress is essential for evaluating the effectiveness of procedures like the Belkyra double chin treatment. Most providers schedule a follow-up appointment around 6 to 8 weeks after each session to assess fat reduction and determine whether another session is necessary. During these assessments, providers may use:

  • Before-and-after photos to visually compare results.
  • Physical examination of the submental area to evaluate changes.
  • Patient feedback on contour changes and overall satisfaction.
  • Measurement tools to track fat volume reduction.

Providers encourage patients to take their own progress photos using consistent lighting and angles. This helps them notice subtle improvements over time. Providers typically review the final result about 12 weeks after the last treatment session, when the full effects become visible.

Conclusion

Belkyra offers a nonsurgical solution for reducing submental fat (double chin) and achieving a contoured jawline. Unlike liposuction, which delivers immediate volume removal, Belkyra works gradually, with visible changes typically appearing around the 4 to 6-week mark. Most patients will need multiple treatments, spaced out over several months.

While swelling and bruising are temporary, optimal results may take 12 weeks to fully manifest after the final session. Once fat cells are destroyed, they are permanently eliminated, but maintaining a stable weight is essential to preserving the outcome. Belkyra offers a safe, gradual, and effective solution for those looking to reduce their double chin and enhance facial contours without surgery.
