First, I want to acknowledge how heavy this has been for you. Feeling like you have to control your smile or hide parts of yourself just to feel “normal” is exhausting—and you’re not imagining what you’re seeing. What you’re describing is a real, anatomical pattern, not a flaw or something you caused. Looking at your photos and your description, this appears to be driven by chin shape and muscle behavior, not aging or weight. What’s likely contributing 1. Strong mentalis muscle (dynamic chin prominence) When you smile, the mentalis muscle contracts and pushes the chin upward and outward. In some people—especially those with inherited chin structure—this creates a more prominent, squared, or “masculine” appearance only during expression. This is why it feels much worse when you smile. 2. Chin projection relative to the rest of your face Your chin itself isn’t “too big” in isolation—it’s that its projection and muscle activity are stronger compared to your softer facial features. This imbalance is what your eye is picking up on. 3. Genetics (and yes, parents pass this down) This is very commonly inherited. The good news is that structural concerns like this are also some of the most predictable to improve when treated correctly. Options that actually address the root cause The goal here is softening and feminizing, not shrinking your face or changing who you are. • Neuromodulator (Botox-type treatment) to the mentalis This is often the single most impactful treatment for concerns like yours. Relaxing this muscle: Reduces the “balling up” of the chin when smiling Softens projection without adding volume Allows you to smile naturally without forcing it For many patients your age, this alone makes a dramatic difference. • Conservative chin contouring (only if needed) In select cases, very subtle structural balancing (not enlargement) can help harmonize the chin with the rest of the face—but this is never about making the chin bigger, and it’s not always necessary. • What usually does not help Overfilling nearby areas Aggressive contouring Anything that adds bulk These often make the chin look stronger, not softer. A very important thing to know You are not too young to address this—but you are at an age where conservative, reversible approaches are the smartest place to start. Many people wait years carrying this discomfort when the solution is actually quite straightforward. And just as important, you should never feel like you have to hide your smile to be acceptable. Your face isn’t wrong—it’s just responding to muscle patterns that can be softened.
