The first time I got trapezius botox, I got about 100 units, and a year later, when I got my second dose at another hospital, I got 200 units. The first time I got it, I got it at a hospital in Gangnam as part of an event. I don't remember much because there were a lot of people and it was done in a hurry, but the effect was good for the price. The second hospital treatment was at a dermatology clinic near my house, but after getting the treatment, another dermatology clinic performed armpit hair removal treatment, so it didn't have the same effect as the first dose, probably because I had to lie down (never lie down after receiving Botox. ㅠㅠ) Because of my job, I always carry a 15-inch laptop. Where do I go after I go? I wonder if I'm an athlete. My trapezius muscles are fully developed and I also have severe shoulder stiffness, so I started getting Botox. Maybe it's because my condition is so severe, but it definitely eases to a visible level in about 1-2 months (I'm not sure right after or after a month, but it's definitely 6 After about 8 months, I can feel my trapezius muscles rising) After about 2 days, the habitual stiffness in my shoulders has almost completely disappeared. That's why I get 200 units about once a year. Cost is important when choosing a hospital, but I think the doctor is the most important. !
