Is Botox effective for wrinkles around the eyes, too? Haha

Lately, I feel like the fine lines around my eyes are getting deeper every time I smile, and it's really bothering me. ㅠㅠㅠ In the past, they appeared naturally when I smiled, so I didn't worry too much about it. But now, they feel like they remain even when I'm not smiling, so I'm worried that I look older than my age. That's why I'm looking into eye Botox, and I'm wondering if it's effective.

I've seen a lot of talk about having to be careful with Botox around the eyes because the skin is thin, so I'm even more worried lol. I really would hate it if I got it done wrong and ended up looking awkward when I smile or feeling like my eyes aren't fully open. I'm also wondering if it's possible to just naturally reduce wrinkles.

I've also heard that the effects of eye Botox don't last long, so I'm worried about that as well. I think it would be a burden if I had to get it done frequently. However, if the results are 확실 (certain/guaranteed), I would like to try it at least once.

If anyone has gotten Botox around the eyes, I'm curious about the actual results!! Please also let me know if the natural look lasts when smiling.
