The last twenty years or so have seen an incredible amount of research and development in the field of skincare. If we knew twenty years ago, what we know now about the importance of skin care maintenance, would it have made a difference to the way we looked after our skin? Imagine if we had all avoided the sun, not smoked and made a point of drinking two litres of water every day, one has to wonder how much younger we would look today. On the flip side, because of all our mistakes in the past we have built an enormous health and beauty industry specifically to counteract our bad skin etiquette.
