Are there any precautions to take when getting wrinkle Botox?

I feel like I'm getting old. Every time I take a selfie or laugh hard, I get startled by the deep wrinkles forming around and under my eyes. No matter how much eye cream I apply, it doesn't help since the lines already follow my expressions, so I guess I need to get wrinkle Botox before they get any deeper. However, I'm a little scared because I've heard that if the injection is done incorrectly around the eyes, it can make your smile look awkward or your eye shape look distorted. For those of you who have gotten wrinkle Botox around your eyes for expression lines, did the lines smooth out naturally without making your expressions look unnatural or feeling awkward? How often should I get injections to maintain the effect? ​​Wrinkle Botox Please share any precautions you may have during the procedure!
