You can’t lose weight to make your cheeks bigger by eating betel nut, but you can make them smaller by injecting Botox. When eating betel nut, the biting muscle chews, and in the long run, the biting muscle becomes enlarged, which is manifested as “big cheeks”. This change is not purely obesity or fat accumulation, so it is not possible to lose weight through ordinary dieting. If you want to eliminate the biting muscle, you can try to inject botulinum toxin to paralyze the nerves that innervate the biting muscle, so that the biting muscle atrophy, to achieve the so-called thinning effect of the face. It is not recommended to chew betel nut for a long time, because chewing betel nut can not only make the biting muscle enlarged, which affects the appearance, but also, more critically, it has been proved that betel nut alkali in betel nut is a kind of carcinogenic substance, and chewing betel nut for a long time can increase the incidence of oral cancer, so for the sake of health, it is advisable to eat betel nut sparingly. Botulinum toxin injection is recommended to go to regular hospitals, operated by professional doctors and nurses.
