I am looking for a non-surgical solution to smooth out the chin area below the mental crease? (Photos)

Botox is a good idea to minimize animation deformities.  You can also try fat grafting to the chin to help improve the contour. 

Thank you for your question and photos. Botox is a neuromodulator that works by relaxing the muscles that lead to the formation of certain wrinkles. It is also effective in relaxing the masseter muscle in the jaw to relieve persistent clenching. However, it is not terribly effective in smoothing away lines and wrinkles in the chin. While it is difficult to make a full assessment from images alone, I would likely recommend a combination of Botox to reduce the clenching and dermal fillers to smooth out the mental crease. Make sure you work with a board-certified dermatologist who is also an expert injector, since this treatment will require precise placement and a gentle touch to achieve a smooth, natural result. 

While Botox can effectively address your clenching and any enlargement of the masseter (jaw) muscle, it is not the most effective in reshaping the chin. However, there are other non-surgical options for this purpose, including the careful use of dermal fillers to create a more attractive lower jawline. I encourage you to book a consultation with an experienced, board-certified plastic surgeon who can give you a full assessment and design a treatment plan based on your specific needs. Good luck to you!

Botox only lasts 4 to 6 months. That means getting maintenance retreatment at least twice a year. The hyaluronic acid filler will last for about a year. Understand that there is fundamentally nothing wrong with your chin and the only real reason to treat your chin is that you are asking for service. The big risk with botox is that treatment of the mentalis muscle can easily be out of balance. That causes disturbing wading of the chin. For that reason and the treatment time frame, I generally prefer to use Restylane or Lyft for chin treatment. 

Thank you for sharing your excellent question and photographs.  Most likely with a combination of Botox and dermal fillers you will see improvement in the depth of the crease present.  See an ASPS board certified plastic surgeon in consultation to discuss. 

Treatment for chin dimpling (""pebble chin"" or ""orange peel"") is Botox injected into the mentalis muscle. This typically gives great improvement to the appearance of the chin. Results take about 1 to 2 weeks. I suggest getting a formal evaluation with a board-certified cosmetic dermatologist. Best, Dr. Emer

I think that a combinatiomn approach best. Botox/Dysport/Xeomin will stop the tensing of the chin but this will not get rid of the crease . I would use Restylane Lyft or Radiesse to help with creasing and shaping. Would be best if do neuromodulator first, get it working and then add filler when relaxed. 

Thank you so much for your question regarding botox.  Botox injections to the mentalis muscle would relax your chin and create a softer appearance.  It would not require many units.  If that did not give you the results you were looking for you could progress to dermal fillers.  I believe botox alone would offer the improvement you are looking for.  Of course I am not able to tell via pictures for sure if this is the correct treatment for you. 
I recommend an in person consultation with a board certified provider for a proper evaluation.    

Please schedule a consultation to talk about fillers and neuromodulators. Fillers will help soften that crease. You expect some swelling and discomfort after the injections but that will go away in a few days. 

Botox should work very well for your chin issue. it will not take but about 8 units and then after 10 days or so if it is not as smooth as you want, then add a little filler
