Review of jaw botox and closed mouth

Now, I get chin botox every 1 year to 1 year and 6 months, but when I first got chin botox, I believed in the saying that it should be done every 3 to 5 months? The first Botox treatment was fine, but after the second treatment, I yawned and my mouth was closed. The degree to which you have to close the chin with your hand to close it; ㅠㅠ I didn't get a repeat treatment cycle, but I think it's because I just had the treatment. After that experience, I realized that the re-treatment cycle varies from person to person, and it can also vary depending on the drug or the skill of the doctor. Besides, I hadn't even thought about my cheeks, but my cheeks were dented and I was sober. Botox is still being treated and I don't think it's very difficult, but still... you have to be careful! ㅠ ㅠ You may think that it is too light, so I will write a review that does not shut my mouth.
