16 year old, should i bs?

I feel like i need to train my masseters to get a better lower third but i have no idea how to, i looked into mastix gum drops and i wanted to buy it. I was also wondering if i should start bs'ing with a massage gun since i've seen it gives the right amount of impact force or something, havent been on the forum for long. (Also what can i do against my bad canthal tilt?)
