Working as a masseur is considered a high-risk occupation for irritant contact dermatitis. Causes of irritant contact dermatitis are wet work; contact with soaps, detergents, and disinfectants; irritating components of massage products; and chronic mild trauma due to manual work. Masseurs are exposed to a whole range of potential contact allergens, such as essential oils, carrier oils, preservatives, fragrances, emulsifiers, and rosin. Olive oil has sensitized masseurs and given occupational allergic contact dermatitis. It should not be used to treat dry skin. Masseurs may also contract fungal infections from clients when massaging infected skin.
