I had to take pictures in a few days, so I chose a treatment with no downtime. There was no real swelling, redness, bruising, or anything else. The cheek neuter was hot, so it didn't hurt that much even when I raised the level. I recommend Shrink instead to people who can't tolerate pain. This is my first time trying it. I was told it could hurt even my gums, so I thought it would be true, but my gums actually hurt ^^.. Still, I can tolerate pain well, so I raised the level and applied it. For reference, I applied numbing cream for about 20 minutes. Before playing ball, I need to get enough sleep and control my condition well. I felt like I had a bit of a headache after using it. I chose the cheek newer to improve my jawline. Now that it's the second day, I don't know if it's because of my mood, but it's definitely effective. I feel like it's relieving the headaches that only I can recognize. Plus, I heard a compliment about my face shape at the beauty salon today.. Recommended for people with fat cheeks + those who have concerns about their nasolabial folds.
