I'm the one who almost grabbed the doctor by the collar because it hurt so much during Ultherapy ㅠㅠ. After that, I was too scared to get a lifting procedure, but after getting so many recommendations for a dermatology clinic in Nonhyeon-dong, I visited Cheongdam Gowoon Sesang Dr. G Dermatology for CoolSonic. They said that because it's a pen-type device, they can shoot strong energy at sagging cheeks, double chin, and other areas. They examined each spot super meticulously. There was absolutely no stinging or pulling sensation; in fact, it felt refreshing, so I kept chatting away in the middle of the session haha. Since it didn't hurt, I asked them to set the energy level to the highest setting. Other people say they can never get Ultherapy again, but CoolSonic is super convenient. As soon as it was over, I looked in the mirror and my skin elasticity had lifted dramatically, my jawline and double chin were completely smoothed out, and my sagging cheeks had lifted up so much I was speechless. There was absolutely no bruising or swelling, so I felt confident when I took off my mask. Every time I do my makeup, my contours are alive, so looking in the mirror is a joy. There is a reason why this Nonhyeon-dong dermatology clinic gets so many recommendations. The value for money is insane, and the results last a long time. You definitely have to go. Do it!!
