Are sagging cheeks inevitable after facial contouring?

Are sagging cheeks inevitable after facial contouring? Or will it have a greater impact depending on the surgical method? A while ago, when I was looking up the side effects of facial contouring on the Internet {and even looked up surgery videos on YouTube}, I thought to myself, “There is no such thing as fat loss in watermelon because the skin is separated from the bone...” So I looked it up and it said “ㅊㄷㅁㅇㅁㄷㄱ”. The hospital said that when facial contouring is done, it is done with ultra-fine incisions that only make 3MM incisions. It doesn't cause massive sagging, but they just wrote something about the effect of 45-degree cheekbones. The theory is that facial contouring surgery is done with minimal dissection by making only 3MM incisions. Is it possible? And when I looked at the reviews on Google Maps for that hospital, I saw a review written by someone and it said something like this. Am I not good at searching on the internet? Is there only a cheekbone surgery on the face and lines on the inside of the mouth and hazel eyes?
