I went to Gangnam Tsㅁ and got botox and contour injections together. Botox is usually given regularly, so it seems to be effective when it is just taken.. They say that the contour injection takes up to the 3rd time to be effective.. You only got the 1st shot, but your chin has gotten a little slimmer? I think there is a feeling. I don't have much fat on my cheeks, so I gave a lot of injections around the chin. I think it will be more effective if I get the 2nd and 3rd shots~ I'm going to go get the 2nd shot soon!
