how to get rid of double chin overnight is unrealistic as it typically requires time and consistent effort. However, some methods may help reduce its appearance temporarily. Facial exercises, like chin lifts and tongue stretches, can help strengthen and tone the muscles in the neck and jawline. Additionally, maintaining good posture and avoiding slouching can minimise the visibility of a double chin. Using contouring makeup techniques can create the illusion of a more defined jawline. Lastly, staying hydrated, maintaining a healthy diet, and managing weight through regular exercise can contribute to long-term reduction of a double chin.
