Is 19 too young for Botox for non-comestic reasons?

Hi Huh...
Botox injected into the masseter muscles for TMJ is very effective for all ages, so no, you are not too young to have Botox treatment to relieve your TMJ Syndrome problems. Make sure to choose your injecting physician most carefully as Botox injection in the TMJ is an advanced technique to get right. Good luck and be well.

Thank you for sharing your question. No 19 is not too young to receive Botox but be sure to seek out a specialist in consultation to discuss your concerns.

botox can be used at any age if you ahve consent (18 and older)

at home peels like cosmelan, enlighten and aerify along with dermarolling (EmerageSkin roller with anteage AERIFY MD ampules weekly, see link) should be started now to prevent further aging.

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.
