Please recommend a dermatologist

Now that I'm in my 40s, I'm concerned about the wrinkles around my eyes.

I have severe wrinkles around my eyes when I smile, and I heard that getting botox would help.

Since it's around the eyes, I'm a little worried about the side effects, but I'd like to ask for recommendations from those who have had it done.

A place where you can see the effects of botox injections, a place that doesn't hurt much

If you know where to go, please give me some information.
