Thank you for sharing your photo and being so detailed about your concerns—it really helps to understand what’s happening. From what you’re describing, the double chin and indentation when you talk or smile are likely related to the underlying structure of your chin and jawline, including the chin bone, soft tissue, and how your muscles move when you speak or smile. Even in people who are very lean, the chin can appear “indented” or create a double chin look if the chin is slightly recessed, the muscles in the area are active, or there’s looser connective tissue in that region. This isn’t about weight, but more about anatomy and movement. There are a few ways this can be addressed subtly: Dermal fillers can help enhance the chin and jawline, filling in indentations and giving the area more projection, which can reduce the appearance of a double chin. Muscle modulation (like Botox) can sometimes help if overactive muscles are contributing to dimpling or movement-related folds. Combination approaches can provide a smoother, more balanced profile while still looking natural. The key is subtle, precise enhancement—too much filler or volume can actually exaggerate the problem. With the right approach, you can soften the indents and improve the chin’s overall shape, which often improves both the appearance at rest and while talking or smiling.
