Hi, Thank you for sharing your concern and the photo—it really helps in understanding the dynamics of your smile. The deep creases you notice when smiling are commonly called nasolabial folds or “smile lines.” These lines are partly caused by the movement of muscles around the mouth, especially the zygomaticus muscles, which pull the corners of the mouth upward when you smile. Botox can help soften the activity of these muscles, which in turn can make the lines less pronounced. Typically, small, carefully placed injections around the upper cheeks and lateral mouth area can relax the muscles that contribute to these folds. It’s important to avoid over-treating here, because these muscles also help you smile naturally, and you wouldn’t want a frozen look. Sometimes, for deeper folds, Botox is combined with dermal fillers, which add volume and smooth the skin more effectively than Botox alone. Botox mainly softens movement, while fillers physically lift and fill in the lines. Everyone’s facial structure and muscle activity are a bit different, so the exact placement and dosage vary from person to person. The key is a subtle approach that preserves a natural smile while reducing the creases.
