What's wrong with my chin and how can I fix it? (Photo)

It appears that you have a deep mentolabial fold and prominent chin. When smiling, your chin soft tissue pad drops below the mandibular plane. Surgical correction of this problem usually requires lengthening the chin and reducing the chin prominence. Additional photos would be helpful.

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

The deep mental crease or indentation in the chin that you are describing is known as a mental crease or dimple. It can be caused by a variety of factors, including genetics, muscle activity, and aging.

There are several treatment options available to help reduce the appearance of a mental crease, including:

Dermal Fillers: Injecting dermal fillers such as hyaluronic acid fillers or collagen stimulators can help to fill in the crease and create a smoother appearance. The results of dermal fillers typically last between 6-12 months.
Botox: Injecting Botox into the mentalis muscle can help to reduce the activity of the muscle and smooth out the crease. The results of Botox typically last between 3-6 months.
Chin Implants: A chin implant is a surgical procedure that involves placing an implant in the chin to augment the area and reduce the appearance of the crease.
It is important to consult with a qualified and experienced practitioner who can assess your individual needs and recommend the appropriate treatment plan for you. They can discuss the benefits and risks of each option and help you to choose the best one to achieve the results you desire.

I hope this helps.
best of luck!

I suggest having multiple in person, consultations with oral surgeons in your community. There are several issues going on with your mandible. Your chin has excessive projection. At the same time, it appears you have a dental overbite collusion with a lack of projection for the back of your mandible.
To make an accurate assessment in this time. She’s an option in your case is a bit complex, and perhaps a bit more than what’s suitable for an online post.
If it bothers you enough to have surgery then contact a few oral surgeon and get proper assessments and recommendations.

The soft tissue relies upon the underlying 'hard tissue/bone/teeth' for contours. You appear to have a lower jaw whereby the lower teeth are 'behind' the chin point in profile. Often this relates to the lower jaw being 'overclosed' and the jawline being more 'square'. It is best to consult an orthodontist and Maxillofacial surgeon for this assessment. Failing that, one can consider a genioplasty to alter the height and prominence of the chin relative to the 'fold'/lower lip. It is quite a common issue
