What causes contact dermatitis?

Contact dermatitis is primarily caused by exposure to a specific allergen or irritant. This condition occurs when the skin reacts following direct contact with substances that provoke an inflammatory response. Allergens can include certain metals like nickel, fragrances, or cosmetics, while irritants might be chemicals like soaps, detergents, or even physical substances like plants (e.g., poison ivy). The skin’s reaction ranges from mild irritation and redness to severe blisters and peeling, depending on individual sensitivity and the nature of the irritant or allergen.

Understanding this mechanism is crucial for those in the beauty and cosmetology fields. Identifying and avoiding such substances when providing treatments or applying products is essential in preventing dermatitis in clients. Proper education on product ingredients and awareness of common allergens is key to maintaining skin health and ensuring safety in various beauty treatments.
