Dry skin after swimming may be due to irritation from the chlorine-containing disinfectant ingredients in the pool, which can be relieved by applying urea ointment, vitamin E cream and petroleum jelly after cleaning the skin. Dry skin after swimming may be related to the disinfectant, because the swimming pool water contains chlorine disinfectant, which is an important substance to keep the pool clean, and the main ingredient is hypochlorite, and prolonged immersion in the water containing hypochlorite will cause damage to the human skin and lead to dry skin. Therefore, the body should be washed with water as soon as possible after swimming, after which urea ointment, vitamin E milk, petroleum jelly, etc. can be applied externally to relieve dry skin. If there is dry skin after swimming, accompanied by local rashes, itching and other symptoms, should promptly go to a regular hospital, by the doctor according to the specific circumstances of the individualized treatment plan, so as not to delay the condition.
