That may be more due to inadequate preventative sunscreen/protective clothing per outdoor time, every one who spends time outdoors without it shows signs of skin aging like the a/b test in one, truck drivers, with the side closest to window showing significantly more wear and tear versus the interior facing side. In addition to sunscreen, there are nowadays a lot of arm/leg covering just for SPF protection even in hotter temperatures - I always wear the arm protection/eyewear when outside.
