I'm lucky, that even as I approach 51 this year, I don't have bad skin, and apart from my goatee, I have plenty of hair, and almost no greys.
Oh, my skin routine?
Fuck all!
I done it all wrong when younger.. tanning oil included! Oops. Oh and I smoke too! Double oops.
Just relax, and enjoy your aging, and stop fussing, or you'll end up looking like Sharon Osbourne (refering to how she looked on the One Show last night (28/05/20)).
Admittedly, I don't have foreign holidays to worry about skin damage, but for the last twenty years, I rarely just sit in the sun. If think with today's knowledge, just sun tanning (even naturally) is not good for skin (admittedly neither is smoking!), so use a good sun protector, and wear a hat ... One that has enough to it, to shade the face, I personally wear a nice fedora style hat.
