I was worried about sagging face and a double chin, so I went to the Gangnam branch of Olympium Chaum and got 60,000 threads of Onda lifting.
I was bothered by the double-chin fat, the jawline, and the corners of my mouth sagging, and my jawline disappearing. The procedure felt like warm heat, so it was more manageable than I expected, and as time passed, I felt a slight hot sensation with a tingling feeling only in the bone area. After it was done, I could go right back to daily life without swelling or bruising, which I liked.
From the next day, I could feel my jawline becoming more defined, and since it is a procedure that builds collagen, I plan to watch it for another month or two. If you are worried about sagging, this may help as a reference!
