From the photos, you appear to have developed moderate laxity in both the lower face and neck, with soft tissue descent contributing to the loss of jawline definition. While photographs provide a helpful starting point, an in-person examination is necessary to evaluate skin elasticity, platysmal laxity, and the underlying facial structure. In my opinion, the most effective approach would be a deep plane facelift combined with a neck lift. By repositioning the deeper facial tissues rather than simply tightening the skin, this technique can restore a more defined jawline and achieve a natural, long-lasting result. A neck lift would further improve the neck contour and enhance the transition between the jawline and neck. If facial volume loss is also present, fat grafting using your own fat can be performed during the same procedure. This helps restore youthful fullness to areas such as the cheeks and midface while maintaining a balanced, natural appearance. The objective is to restore facial support and improve the harmony between the face and neck rather than create an overly tight or operated look. The final treatment plan should always be individualized following a detailed facial examination.
