Thank you for sharing your concerns and photos. From your description and images, it appears you're experiencing mild skin laxity and loss of jawline definition, which can happen even in your 30s—especially after submental liposuction, as it can accelerate skin thinning or reduce supportive fat layers beneath the dermis. Best Options for Skin Tightening and Jawline Contour: Radiofrequency Microneedling (e.g., Morpheus8, Profound RF) Ideal for mild to moderate skin laxity. Stimulates collagen and elastin, improving firmness and retraction of the jawline and neck area. Typically 3 sessions spaced 4–6 weeks apart yield the best results. Ultrasound-Based Skin Tightening (Ultherapy) Non-invasive, focuses ultrasound energy at the SMAS layer, the same layer targeted in a facelift. Can lift and tighten under the chin and along the jawline. Results improve over 2–3 months as collagen rebuilds. Injectable Options (Biostimulators like Sculptra or Radiesse) Help volumize areas where fat was lost (post-lipo) and stimulate collagen production. Useful for restoring subtle contour without adding fullness. Chin and Jawline Filler Hyaluronic acid-based fillers can enhance the projection of the chin and sharpen the jawline. This offers instant contour improvement and can rebalance the lower face. PDO Thread Lifting Can mechanically lift the skin along the jawline and under the chin. Best for patients with mild sagging who are not ready for surgical intervention. Laser Skin Tightening Treatments such as Fotona or Fraxel can be beneficial for skin tone and surface texture. Works best as a complement to deeper tightening technologies. Additional Considerations: Skincare: Incorporate products with retinoids, peptides, and growth factors to support collagen maintenance. Neck exercises may improve muscle tone, although they won’t correct sagging skin. Surgery (e.g., mini neck lift or deep-plane facelift) is a long-term option but likely not necessary at your current level of concern. Your photos show good skin quality overall. Combining non-invasive tightening with jawline enhancement would likely yield the most natural, youthful results.
