I got an acupuncture injection at ㅁJ in Gangnam. I went there because a YouTuber said it was effective there. I've gotten contour injections at most places like ㅌㅅㅁ, ㅃ, ㅌㅅㅇㅍ, ㅅㅋㅇㅂ, etc., but almost none of them were effective. I think the ㅁJ acupuncture injection is the best.
 Instead, the premium acupuncture is said to be a large capacity (5cc), and since this is a large capacity, I had a bad headache due to the steroid.
 It's better to get a regular acupuncture injection of 3cc two or three times. It was effective on my jawline and double chin.
 And since most places get square jaw botox, I recommend just getting it done at a cheaper place.
