Facial aging is not a simple process that affects only one specific area. Deepening nasolabial folds or a less defined jawline should not be considered concerns limited to those areas alone. As the skin, fat, muscles, and skeletal structure change together over time, the overall impression of the face also changes.

Changes such as skin thinning and decreased elasticity causing cheek volume to move downward, alterations in the position and size of fat pads disrupting facial volume balance, and the gradual definition of wrinkles caused by repeated facial muscle movements may appear as separate processes, but they generally progress simultaneously.

Therefore, even when facial aging appears simply as “sagging” on the surface, it reflects complex changes occurring across multiple layers beneath the skin.
