Skin hygiene and care refers to consistent skin cleaning with mild soaps and skin care, usually including moisturizers. Good skin hygiene and moisturizers are important for patients with lymphedema for prevention of skin breakdown or infection. In the past, in patients receiving radiotherapy, washing the skin and continuation of use of moisturizers or lotions on the skin in the radiation field was controversial. Effects of skin hygiene and care, such as moisturizers, was evaluated in patients with cancer related to lymphedema and radiodermatitis.
