I went to get filler for the corners of my mouth, and it was recommended that I get 1cc of filler + Botox, and the results are amazing... I tried it because my lips were short and my upper lip was curled, and I was more satisfied with the botox on the corners of my mouth than with fillers! 1. Botox at the corners of the mouth: Botox is applied to the depressor muscles, so it is much more comfortable because the muscles that droop when you stay still are taken care of! It made me want to get Botox on all my depressor muscles. The best time was about 3 days after getting it. 2. Mouth corner filler: I only put in 1cc, so I’m not sure about the horizontal or curled effect… It became thicker overall, but as the swelling went down, the part where the filler was added to lengthen the upper lip got rolled in, making the lips look smaller and creating nasolabial folds. Would it have actually improved if more had been added? 3. Conclusion: Satisfied with Botox, dissatisfied with filler. I don’t think the place I went to is good at lip fillers… ㅠ If you have insufficient lip volume like me, you are good at lip filler, so go ahead and put in at least 2cc*^^*
