I was in one place and wanted to go to another place too. I received it from a total of three places. In conclusion, it was effective if it was a place that confirmed the authenticity of the product. In some places, there were cases where the doctor brought a syringe from outside the treatment room without even checking, gave the injection as soon as he came in, and then disappeared. It was ridiculous and embarrassing. I had some pain in my jaw muscles, so I got Botox, but it didn't seem to work at all and I spent several months unable to get it anywhere else because I was worried about tolerance. Make sure to go to a place that confirms the quantity of genuine products. The introduction was a bit long, but I think it would be okay to recommend a hospital as long as it verifies the genuine quantity as mentioned above..! If there is a hospital you want, you may want to refer to this point. The hospitals that did not confirm are large PDI clinics that are located in Seoul and other regions. And if you have jaw muscle pain due to poor sleeping or chewing habits, we recommend getting Botox regularly! I am so satisfied with this aspect rather than the external aspect that I get it regularly :)
