At 50, it’s very common to notice a combination of skin laxity, jowling, and loss of facial volume. When the face is losing volume, simply tightening the skin may not fully address the “sinking” appearance. Since you’ve already tried Sofwave and threads, I would approach this a little differently. For someone with noticeable volume loss, restoring volume and improving collagen quality together can often create a more balanced, natural-looking result. For collagen stimulation, treatments such as Sofwave, radiofrequency microneedling, certain lasers, and biostimulatory injectables such as Sculptra can stimulate your own collagen production. Results are gradual and usually develop over several months rather than immediately. For the jawline specifically, if the issue is primarily loose skin, energy-based tightening can help. If the jawline looks less defined because of volume loss, carefully placed filler or a collagen-stimulating treatment may provide better structural support. The key is not to overfill the lower face, because too much product can actually make the area look heavier. At home, the most important collagen-preserving steps are daily broad-spectrum SPF 30–50 and a retinoid, provided your skin tolerates it. A healthy diet with adequate protein, avoiding smoking, and maintaining stable weight can also support overall skin health. The important thing is that collagen stimulation and volume restoration address different problems. Based on your description of both sinking and fat loss, I would focus less on simply doing more tightening and more on determining how much of the change is from laxity versus volume loss.
