Your natural collagen network gradually weakens with time. Supporting fibers become less effective. Skin begins responding more to gravity. Previously sharp contours soften along the jawline.

The youthful fullness in your cheeks slowly shifts downward. Volume accumulates along the jawline. This creates heaviness and disproportion where definition once existed.  

Facial muscles naturally lose tone similarly to body muscles. This removes internal support that once maintained crisp contours. Definition decreases even  when skin quality remains good. 

Your facial skeleton actually undergoes small but significant changes with age. Support areas diminish. When this foundation alters, all the tissues above follow gravity's natural direction. 

Your skin's natural elasticity fades yearly. That youthful "snap back" quality diminishes. This magnifies structural changes. Effective treatment strategies can significantly improve appearance alongside rebuilding architecture.
