Laravel文本区域验证最佳实践

I am not sure what kind of validation I should use for comments in E-commerce website that I am currently developing. It is not much I want to validate but I'm worried about security.

So what is the best practice?

My code now looks like this:

$this->validate($request, [
    'comment' => 'max:1000',
]);

Is it safe to leave it like that?

It depends on your needs but I could suggest some

$this->validate($request, [
    'comment' => 'required|min:3|max:1000',
]);
