Avoid products that contain allergenic fragrances or preservatives which could cause skin reactions.
Use cleansers containing moisturizing active ingredients (glycerine, milk protein, shea butter) and surgras agents which restore the hydrolipidic film that protects the skin.
Avoid alcohol-based lotions which tend to dry out the skin, Pat dry the skin rather than rub.
Avoid overheated environments and cover yourself up appropriately (gloves, scarf, etc.) in the cold.
Bathe and shower with lukewarm or even slightly cool water.
Apply a moisturiser every day and especially after swimming because chlorine dries out the skin!
