As far as I'm concerned much of it is modern day snake oil salesmanship.Thank Fuchs, just what we need, more skin therapy, can never have too much concoctions to chuck on our skin.
Mason shaved his beard a bit, cause he messed up his trimming, and his face was red, so his moisturisers and beard balms aren't working.
I'd love to see a real world test. Identical twins. From birth, ensure they live as close to similar lives as possible in terms of where they live, careers, diet, sleep, exposure to sunlight, stress, exercise etc. One twin only ever uses good quality soap and basic moisturiser. The other uses various skin care products that claim all sorts of stuff.
Compare their appearance and healthiness of the skin each decade. Would love to know the difference
