The muscles in the lower face are constantly in motion. Over time, the skin in this area can lose elasticity, leading to sagging and the formation of a double chin.
In addition to the effects of skin aging, fat cells tend to accumulate under the chin, forming an unsightly bulge. This fat is often resistant to dietary changes and physical activity. Even with successful weight loss, it can be challenging to eliminate fat deposits in this region. Factors such as repeated weight fluctuations or genetics can also contribute to the formation of a double chin, making it harder to address.
