Why is my chin sticking out so much, it looks like a Witch's chin —can it be fixed? (Photos)

It appears that you have a large soft tissue pad and prominent chin with a deep mentolabial fold. Both aspects need to be corrected in order to provide you a more feminine appearance. I would recommend a bony reduction of your chin with simultaneous reduction of the soft tissue pad. The surgeries can be performed simultaneously in the office with intravenous sedation.  

Dear helpplease1000,
it is hard to tell for sure without an examination. If your chin bone is the problem, then you will need an osteotomy in order to get improvement. In case of excess fat tissue in that area, liposuction might be the best solution. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

Based on just one picture it appears your chin protrusion is a combination of both bone and soft tissue excess. But regardless of its tissue composition it is going to require surgery to reduce it.
