Can you tell right away when the thread breaks? It's been 9 days since I had it, and I hear a slight popping sound in my left cheek area... ㅠㅠ And when can I definitely feel if my cheek sagging has increased? It looks like my cheeks are still swollen, but I'm not sure about the effect... There's a slight dimple under my cheekbone... ㅠㅠ The hospital said it will get better over time.
