Common causes of dry skin include:
Places that require air-conditioning or dehumidifiers will drastically reduce the humidity in the air and cause your skin to dry up.
Warm Baths & Showers
Try and avoid taking too many long showers with hot water. Spending too long in the sauna or jaccuzi can also have detrimental effects to your skin. The heat from these activites can damage and irritate the surface of the skin, causing skin to get drier even though it feels warm and moist while you’re at it.
Soap & Detergent
Coming into contact with dishwashing fluid or harsh soaps can cause skin to become dry and flake off. This is because these soaps have an agent that can destroy the natural skin barriers and cause skin to dry out.
