How long does the effect of glabellar filler last?

Lately, I've been bothered by the wrinkles between my eyebrows, so I'm thinking of getting filler treatment.

I'm also curious how long it usually lasts after one treatment, and is it okay to get it regularly?

From what I've briefly looked up, it is said to last about 6 months, so to make the filler treatment last longer

Is there a specific way to manage this? Ideally, I would like to keep it going for a long time without getting it too often.

If you get fillers, you usually feel like you'll keep getting them once you start (if you're satisfied).

I was also curious about how you manage it.

I plan to take good care of it so that it lasts a long time. Not just between my eyebrows, but also my nasolabial folds and forehead area.

I'm still thinking about it, but I'm planning to get fillers between my eyebrows first before deciding.
