There is a product called Nanoblur which helps to deflect/diffuse light so that lines and crepey skin don't show as much - I use it to great effect on my ageing face and the backs of my hands. They also make something for reducing wrinkles etc.it is called Snoxin. I think they were the first to deal with HD cameras and so invented formulas that hid and repaired problems with ageing skin... - it is a good brand, please look into it! I buy mine at the local drugstore (in Canada) and it is reasonably priced.
