The layer of skin lining the back of the hands is very thin and over the years tends to mark and thin. The repeated action of water and cleansers leads to a reduction in the hydro-lipid barrier; the skin becomes more reactive and sensitive. The protective film is regenerated fairly quickly but, if the stress to which it is subjected is continuous, it will struggle to recreate itself, leaving the skin unprotected. It will be easier to have chapped, dehydrated and dry hands marked by fine lines. Constant and frequent use of hand creams restores water and nourishment to the skin: redness fades and dehydration lines disappear.
