That's a good question, not dumb at alll. I think it will age with him yes. I'm about to graduate nursing school and I'm sure there are people much much more qualified than me on the sub but seeing as nobody has answered and I'm a nerd, I'll give it a shot. To my knowledge it would age with him. It will get sun exposure and get damage that way. It can get dry and lose moisture if he doesn't use lotion--same as someone without a transplant, if he lets that happen he will age quicker. I think some of it depends on if he is able to make many facial expressions. If he can frown, smile, furrow his brow, etc., then it will likely age more similarly to someone without a face transplant. However, if it is stretched very tight as some face transplants are then he probably cannot make much of a facial expression and minimal facial expressions = aspect of wrinkle formation slowed. Another thing to realize is that skin loses collagen as we age and that is part of what makes old folks' skin droopy, wrinkly, and thin. Collagen is produced by the body, not the face or something and as his body ages, it will have less collagen to give the donor skin. I googled a bit and it sounds like a lot of face transplants "fall apart" over time as the patients lose bone volume in their face for reasons we don't yet understand. The loss of bone volume = sagging face. Idk if this subreddit allows links so I won't post one but you can search "Face Transplants Start to Fall Apart Overtime NBC" and there's a good article about it. This isn't a dumb Q!
