My partner played lots of outdoor sport in his youth so he has some skin damage but from his mid 20s when I met him I encouraged proper sun safe behaviours and to moisturise. We live in Australia for Christ sake, this sun is not fucking around.
He’s got mates of all ages but some of the blokes in their late 20s seem to think looking after their skin is a feminine trait and they play outdoor sports. When he’s been out with these guys, people think he’s the youngest despite being over 10 years their senior.
It’s so silly. Put some sunblock on and moisturize. It’s not that hard.
