Will Botox in the massater muscle reduce nasolabial folds or make them more prominent?

nasolabial folds are not effected by jawline treatments. but I would suggest starting at home peels like cosmelan, enlighten and aerify along with dermarolling (MTS roller with anteage MD ampules weekly, see linkt) should be started now to prevent further aging. folds are best treated with morpheus, threads, and fillers in office.

For facial rejuvenation, I would suggest a combination approach of
1) skin care with products and PRP/microneedling
2) PDT light therapy few times a month with growth factors
3) laser treatments like clear and brilliant regularly and a few times a year Fraxel/halo Viva, Co2/Erbium
4) Sculptra injections a few times a year for collagen production with fillers like juvederm/restylane/belotero/radiesse/bellafill
5) thermage/ultherapy for yearly skin tightening with or without PDO or cone based instalift threads for lifting
6) botox every 2-3 months to stop movement lines and prevent lines at rest
7) deep microneedling RF like Fractora/morpheus8 for tightening of the skin
8) Vascular laser like vbeam/excel V or BBL forever young treatment every quarter (3-4 months)

Best, Dr. Emer.

The masseter is a strong muscle that starts at the cheekbone (zygoma) and inserts at the angle of your jaw that aids in chewing. Injecting the masseters with neuromodulators can be an effective way to treat myofascial pain/TMJ dysfunction as well as soften the contour of the jaw when the muscle is too prominent. With regards to your concern, the nasolabial fold is a function of the mimetic muscles of the face and its fibrous attachments, which is independent of the muscles of mastication (i.e. masseters). Furthermore, the nasolabial folds is situated much more medial and distant from the masseter muscle, such that injecting it with neuromodulators should not worsen the appearance of your nasolabial folds. I hope this answers your question, and if you decide to get the injection, I hope it will help with your TMJ problem!
