Belkyra has passed a series of clinical trials that demonstrated an excellent track record of safety. The most common side effects include tenderness, bruising, redness, and swelling surrounding the injection site, which will eventually resolve on their own. In the meantime, you can treat them at home with ice packs and over-the-counter pain medications.
Initially, the swelling may temporarily increase the prominence of your chin. However, you should welcome the swelling as a sign that the treatment is working, because it happens as a result of Belkyra actively breaking down the fat cells.
