I tried contouring injections at another hospital, but at that time I got steroids and I also had bleeding. That was about 3 years ago? I guess it was like that. I took it without any steroids, but there were no side effects and the effect seemed to be good, so I'm satisfied. ★★★★ About four stars? It's amazing to see a big difference when comparing pictures :) I heard somewhere that contour injections are more dramatic when combined with Botox, so I did it together . Botox also takes effect gradually after a month. I also heard that the effects of contour injections gradually come out after the 2nd or 3rd session. So, I was worried for a long time until I got the first and second shots . I wondered if this would really reduce the fat in my cheeks. ㅠㅠ But then I got all 6 shots, and the square jaw Botox effect came out, so my lower jaw line was completely different. Before, my cheeks were puffy and my chin was round. It looked a bit out of place, but now that the jaw line has become sharper, should I say that the overall impression has become more sophisticated? I've tried liposuction for double chin, but I didn't see much of an effect...ㅠㅠ This is a personal difference! I just got it done at a plastic surgery clinic.. Compared to liposuction, contouring injections are much easier, no anesthesia, no pain, and you can live your daily life! It's a bit annoying to have to go multiple times instead of just once ... but I'm confident that it's an excellent choice as a way to look prettier(?) without being noticeable.
