Can hand wrinkles also be alleviated with injections?

My mom has pretty fine skin, so even though she works in the fields, her skin remains smooth and in good condition.

My mom says that he used to look old for his age, but he's getting younger and younger as time goes by haha.

But perhaps because he is in his 60s and has a job that requires a lot of use, his hands are wrinkled.

Now that I look at it, it feels like my face and hands don't match, and I'm upset because they look too thin and wrinkled.

Are there any injections or procedures available to smooth out hand wrinkles in situations like this?
