Contact dermatitis causes and risk factors

Reading time: 1 min

Contact dermatitis is a non-contagious skin disease that can have many different causes: 

Person wearing a mask in a work environment

Working in sectors in which contact with toxic chemical substances or irritants is common, such as the metallurgical industry, aesthetics, healthcare, the food industry, cleaning, construction and painting.  

Perfume and deodorant

Fragrances and perfumes are the second most common cause of contact dermatitis in Spain and the main cause of cosmetics allergies, ahead of preservatives (products added to cosmetics to conserve them such as parabens, benzoic acid or benzyl alcohol, amongst others). Amongst fragrance allergies, deodorants are the cosmetics that most frequently cause allergic dermatitis. To confirm which allergen causes the reaction, it is essential for the dermatologist or allergist to carry out epicutaneous tests on these substances.  

There are other risk factors, such as:  


Being a woman. 

Woman growing older from childhood to old age

Age (greater risk with age).  

DNA molecule or helix

Certain gene polymorphisms.
