How should I choose the procedure for my parents?

Hello. Today, I am writing not to discuss my own skin concerns, but because I want to book some dermatological treatments for my parents. I am struggling to decide which lifting procedures to choose. As you can see in the photo, my dad has quite a few wrinkles. In particular, the wrinkles around his eyes are very deep. I know it isn't easy to get rid of wrinkles that have already formed deeply, but what kind of treatment would be best to book for him to help improve them even slightly? I know absolutely nothing about lifting procedures. I don't mind the price, but I would prefer it not to require too many sessions. I think my dad might find it bothersome.
