My chin is fleshy and long. It protrudes more when I smile. What procedure do I need to reduce it for a natural look? (Photo)

A chin reduction done through a submental approach can change your pointy long chin to a shorter and more rounder one. The chin bone needs to be reduced both vertically and horizontally and this may also require some soft tissue removal as well. It is also possible that an intraoral bony genioplasty with wedge reduction my suffice as well but this will require better pictures to assess. Smiling and non-smiling front and side view pictures are needed for a more complete assessment of chin reduction options.

your lower jaw and chin area can be recontoured to reduce the 'look' you dislike. The jaw is quite narrow so that you could benefit from changing its dimensions vertically, and width-wise. The lower front incisors may be tilting backwards towards the tongue in your growth pattern; so evaluate that area since these teeth support the lower lip. If the lower lip is recessed, then the chin appears more prominent, especially with smiling
