On cold days we like to take a steaming hot bath to get warm and restore our moisture balance. But we don’t realise that a hot shower or bath effectively extracts water from our skin through osmosis. What’s more, both the temperature of the water and the water itself extract the naturally hydrating lipids from our skin. This means that long and hot showers or baths are bad for your skin and may even cause dry skin. So take shorter showers with warm instead of hot water.
