Thank you for your question regarding the appearance of your neck and whether tongue posture might be the cause. While mewing and practicing good tongue posture (keeping the tongue at the roof of your mouth) can help with overall facial structure and alignment, it may not fully address the concerns you have with your neck. If your neck sits lower than your jaw and feels "off," it could be due to excess fat or loose skin in the neck area. In such cases, neck liposuction can be an excellent solution to improve the contour and definition of the neck and jawline. Neck lipo can remove excess fat, tighten the area, and create a more defined jawline, giving you the result you’re looking for. This will help the appearance of your neck and elongate it. Combining good tongue posture with a procedure like neck lipo would likely yield great results, helping you achieve the improved neck and jawline appearance you desire. Sincerely, Dr. Katzen
