Belkyra (Chin)
The Phi perspective is not about weight. It is about the relationship between the jawline and the neck.
At Phi Skin Clinic, we use the principles of the Golden Ratio, the mathematical blueprint for beauty, to ensure your profile has the structural definition it deserves. Whether refining a soft jawline or eliminating a persistent 'double chin,' our approach is always intentional, permanent, and uniquely yours.
Treatment details:
-
Belkyra® is an injectable, synthetic version of deoxycholic acid. When strategically injected into the submental area, it permanently destroys the fat cells. Once these cells are eliminated, the area can no longer store or accumulate fat, resulting in a noticeably more contoured and sharp jawline.
-
Treatment length → 15–20 minutes
Sensation → You may feel a significant warming or "heavy" sensation in the area immediately after the injections, which subsides shortly after.
Onset → This is a gradual transformation. As the body naturally clears the treated fat cells, the jawline tightens over several weeks.
Duration → RWhile some change is visible after the first or second session, the peak results, the sharpest version of your jawline, are typically seen 8 to 12 weeks after your final treatment.
-
These are expected and indicate the treatment is working:
Often referred to as 'social downtime,' swelling under the chin is common for 3–5 days.
The treated area may feel firm, sensitive, or slightly numb for up to two weeks.
Minor localized bruising at the injection sites.
Uncommon Side Effects
Temporary nodules or small "firm spots" under the skin.
Mild difficulty swallowing for the first 24 hours due to initial swelling.
Rare Side Effects
An extremely rare temporary weakness in the smile (resolves on its own).
Prolonged swelling or skin changes if aftercare protocols are not respected.
-
Refinement takes intention. We carefully map the treatment area to ensure fat reduction is uniform and balanced, creating a transition between the chin and neck that is as sharp and intentional as a sculptor’s line.

-
Belkyra® is an injectable, synthetic version of deoxycholic acid, a naturally occurring molecule in the body that aids in the breakdown and absorption of dietary fat. When strategically injected into the submental area, it permanently destroys the fat cells. Once these cells are eliminated, the area can no longer store or accumulate fat, resulting in a noticeably more contoured and sharp jawline.
-
Yes, Belkyra is very safe when administered by a trained medical professional. It is approved by both Health Canada and the FDA (where it is known as Kybella) and has been through extensive clinical trials involving thousands of patients.
-
Most patients require 2 to 4 sessions, spaced 6 to 8 weeks apart, to achieve their "Phi" profile.
-
While Belkyra® is primarily for fat reduction, the inflammatory response it creates often leads to a subtle tightening effect of the skin over the new, sharper jawline.

At Phi Skin Clinic, we prioritize your biological safety above all else. For Belkyra®, as well as most other injectable treatments (like Botox or Fillers), we require that you wait until you have finished breastfeeding before starting your treatment journey.
