I've been long-convinced that companies tell us to wash our face twice a day just to sell us more face wash. I mean, I don't know about most people but I'm not running marathons in my sleep, so unless I'm in a warmer climate (or if one has oilier skin,) a few splashes of water seem to suffice.
(Hair is another story -- the shampoo companies would surely put me on their A-list, as I have to wash my hair everyday, partially as a calming ritual.)
I love talking to people about their personal care routines -- what works for them and what doesn't, and the journey it took to get there, because it's so highly individual.
One crucial thing I've learned is that whenever a buzzy ingredient comes out -- it might very well be my skin's new arch nemesis. Both niacinamide and hyaluronic acid have been touted as skincare wunderkinds for years, and it's become nearly impossible to find anything without them -- but on me, they produce a burn-like rash.
There is a part of me that thinks I would have loved to have been a dermatologist turned esthetician, as I think I would have enjoyed helping people try to find what works for them.
I don't have anyone close to me who is also into such products, so it's always a treat when I visit friends and we literally have a hundred bottles out for each other to try (that's not an exaggeration -- at the last such gathering, I counted 37, and that was just for skin and hair; I didn't even get to counting the makeup.)
