Will the cost of Botox continue to be a burden more than I thought? ㅠㅠ

Lately, I've been stressed about my jawline every time I look in the mirror, so I'm looking into Botox, but I have one concern, haha. It's the maintenance cost!! At first, I thought it just lasted a long time after one injection, but I heard that a lot of people get Botox regularly :)

So when I did the math, I realized that the maintenance costs might actually keep piling up. ㅠㅠ Of course, the duration varies from person to person, but I saw a lot of posts saying that people usually get it redone every few months!! Still, seeing people who say they do it consistently because of their high satisfaction makes me curious again. ㅎㅎ

Especially with Botox, the price difference between clinics seems really huge!! If you look at the promotional prices, there are places that are super cheap, but I actually get worried about the ones that are too cheap ㅠㅠ I'm not sure if it's a difference in dosage or the product lol

Also, I've heard there's a difference between domestic and imported Botox. Is the difference actually noticeable? Some people say domestic products are sufficient, while others prefer imported ones because of the longer lasting effect, so it's making me even more confused. :)

Since it's my first time, I just hope the results look natural for now. ^^ I don't want people to notice right away, so I think I'd be satisfied if it just looked a little more refined. Haha. But it was funny reading Botox reviews and seeing how many people say it's actually addictive. lol

If anyone here gets Botox regularly, I'm curious how much you usually spend on maintenance!! I'd love to hear your honest reviews on whether it feels too expensive or if it's actually better than expected.
