Lately, I keep looking tired even after applying concealer because of the hollowness under my eyes. ㅠㅠ So I've been searching for posts about how long under-eye fillers last, but everyone says the opinions are so different.

Some people say the fillers last quite a long time,

but there are also reviews saying they felt like they faded quickly, which makes me even more conflicted.

How long do you generally expect the results to last without touch-ups?
