How long does the effect of removing deep cheek fat with Ondari Lifting last?

I see a lot of people whose appearance deteriorates as they get older, and it seems that's all because of deep cheek fat.

As my cheeks sag, the corners of my mouth droop too. If I don't smile, I look grumpy and depressed, so I end up hearing people ask if something bad happened, if I'm sick, or if I'm tired for no reason. It's a vicious cycle that causes me stress.

I don't have any fat on my cheeks, so I don't know why they're sagging.

The bigger problem is that lately, people have been saying that my nasolabial folds get a bit bigger when I smile, and in the end, they've engraved fine lines on them.

It still looks like a hairline crack, but once my makeup starts to wear off, that part stands out, so I can't just leave it as is.

I am looking into Ondari Lifting because I want to get rid of deep cheek fat and smooth out nasolabial folds. I think what I like about Ondari Lifting compared to other procedures is that it stimulates both the dermis and subcutaneous fat layers.

Since it targets both the dermis and subcutaneous fat layers, it feels like you can intuitively see the skin tightening up nicely after the Ondari Lifting procedure.

I heard that Ondari Lifting should be done every 3 to 4 weeks. If I receive the appropriate number of treatments at 3 to 4-week intervals, I am curious how long the results will last once the deep cheek fat and nasolabial folds disappear visibly.
