Allergic Contact Dermatitis

Allergic contact dermatitis (ACD) is a common skin condition resulting from an immune response to allergens that come into contact with the skin. In dermatology, ACD often manifests as red, itchy, and inflamed patches, which can develop within hours to days after exposure. Common triggers include fragrances, preservatives, metals like nickel, and certain plants.

Cosmetology plays a crucial role in managing ACD, as many cosmetic products contain potential allergens. It's essential for consumers to read labels and perform patch tests before trying new products. Treatment typically involves identifying and avoiding the allergen, along with topical corticosteroids to reduce inflammation and alleviate symptoms. Education about ingredient safety and proper skincare routines can significantly enhance skin health and prevent future outbreaks.
