Wrinkles that appear when you smile, is Botox the answer?

I usually smile brightly, but these days, I'm careful because of the wrinkles that clearly appear around my eyes and mouth every time I look in the mirror after smiling.

Botox was the first thing that came to mind, but I was hesitant to try it, worried that my muscles might stiffen when I smile, making my expression look awkward or even expressionless. People around me say Botox is the fastest and most effective treatment, but I'm curious about what options would be best for someone like me who wants to smooth out fine lines while maintaining a natural expression.
Rather than simply stopping the muscles, I would like to increase the elasticity of the skin itself to blur wrinkles. Please advise on a procedure with a high satisfaction rate.
