I'm writing this in case I get a refund . I'm afraid there will be a disadvantage in relation to the refund.. Regardless of whether I get a refund or not (a refund would be 99% unreasonable), so I have to deal with something else first. I will keep inquiring about the method for preventing sagging cheeks ㅜㅜ Is there any surgery after sagging cheeks that says it works well?
