I'm wondering if it's better to get multiple treatments with a cheaper Botox product.

Lately, the fine wrinkles around my eyes seem to be deepening significantly, so I have begun seriously considering Botox treatment. When looking in the mirror or taking photos, I started noticing fine lines appearing next to and under my eyes. Even when I am still and not making any facial expressions, it feels like subtle marks are forming, leading me to believe that I need to take care of them before they get any deeper. Since the skin around the eyes is very thin and sensitive, relying solely on home eye creams has its limitations, so I am planning to seek help from a clinic for a procedure.

However, my concern is that my expression might become stiff or awkward when I smile, as if only my mouth is smiling while my eyes aren't. I would like to know if the amount of Botox is carefully adjusted to smooth out fine wrinkles while preserving a natural expression. Also, since there are various types of Botox, I am wondering whether it is better to unconditionally choose the most expensive product, or if it would be better to undergo multiple treatments with a cheaper product.

Since wrinkles around the eyes affect not only appearance but also confidence and the naturalness of one's facial expressions, I want to choose carefully. My greatest wish is to find a way to alleviate fine lines while maintaining a natural smile.
