I'm curious about Jubelook.

I searched for the Juve Look for the first time today, as it's been advertised everywhere lately.
I actually thought this was something only done at dermatology clinics... but it turns out they sell it as a cosmetic product as well... and there are so many different types. It seems like the word "Juvelook" refers to a substance that helps with skin volume... anyway, it’s a bit complicated haha. There are all sorts of opinions about its effectiveness... but for someone like me who is clueless about cosmetic procedures, Juvelook feels the most familiar since I’ve heard of it the most haha. Getting it done at a dermatology clinic is probably best, but... I wonder if there are many people who use it as a cosmetic product? I’m worried that if I go to a clinic, they might administer it with injections... so I’m a little scared ㅜ I wonder if it will hurt... I’m also curious about the recommended number of sessions. But I suppose there will be individual differences with Juvelook too. It’s about finding the treatment that suits you. I want to find a treatment that works well for me, too.
