If very sore and cracked hands are your issue, the Eucerin Intensive 5% Urea Hand Cream (£9) will do just the trick thanks to its star ingredient: urea. Urea is a byproduct of urine (don't freak out, stay with us!) but is also a natural compound found in the layers of the skin, and when synthetically manufactured in a lab it gives the same moisturising benefits.
This one isn't a slather on and go types of creams though. It's definitely one to use at nighttime or to spot-treat individual patches of dry skin as it forms a film layer — this is why it works so well as an extreme dry skin treatment.
