It gets easier to remember when you get dependent on it and your hands hurt if you don’t put lotion on them. That might just be because I live in a desert, though.
A valid point, but this study tested forearms. Most of us wash our hands multiple times a day, wiping off natural oils and dehydrating our skin. We don’t do that with forearms. If we agree the benefits of handwashing outweigh the dehydration, it’s probably better to offset the dehydration with moisturizers.
Moisturizers are often used in the prevention and treatment of irritant contact dermatitis. The present study was to determine whether long-term daily use of a moisturizer on normal skin would affect skin barrier function, hydration state, or susceptibility to sodium lauryl sulphate. Healthy volunteers used a moisturizer on one forearm 3 times daily for 4 weeks. The other forearm served as a control. Afterwards both forearms were challenged with a patch-test of sodium lauryl sulphate. Skin barrier function was evaluated by measuring trans-epidermal water loss and skin hydration by measuring electrical capacitance. Electrical capacitance was significantly increased on the treated arm during the treatment period. After challenge with sodium lauryl sulphate, transepidermal water loss was significantly higher on the arm treated with moisturizer than on the control arm. The results suggest that long-term treatment with moisturizers on normal skin may increase skin susceptibility to irritants.

Or somewhere cold. Or if you wash your hands frequently.
Same, desert folk checking in. My hands THIRST for lotion.

How do we prevent sodium lauryl sulphate
