Hydromol is very good, but better as part of a whole skincare regime. My mum has it put on once her legs have been washed, and then she has blue line stockings on. The skin looks very dry and scaly once it has dried, but it's in fact the Hydromol, and the skin is much better underneath. Definitely as part of a routine though.
I must add, my mum had a bad reaction to Dermol, but has used Doublebase with great success on her arms.
