Seriously, the human race has done without skin care products for millions of years, 90% of the worlds people, the ones who happen to live in less fortunate parts of the world still do without it, and even 90% (more?) of the male population in developed countries do without it. Unless you have a serious allergy which requires prescription medicine, you can really do without skin care products altogether, although the marketing people at Boots and the like want you to believe otherwise.
yes, but those people you mentioned dont work in a pressurised tube in the sky!! being cabin crew and pilots can really dry out your skin and its so important to moisturise if you dont want those horrible wrinkles much before they are due!!
