Abstract

Background: Allergic contact dermatitis (ACD) is a common diagnosis resulting from exposure to a chemical or chemicals in a patient's personal care products, home, or work environment. It is a delayed type of hypersensitivity reaction caused by contact with allergens in the environment. Patch testing is a gold standard to establish the diagnosis. After the causative allergens have been identified, patient education is needed to the proper treatment and management of the patient. Case: Herewith, we report A 23-year-old woman with suspected ACD due to lipstick and was planned to perform patch test. She complained about dry lips that appear after she used new lipstic for about 3 months and there was not history of applying another agent. After recovery, the patch test was performed with allergens that might contact with her lips and the result was positive one in toothpaste allergen while negative in lipstick allergen. Conclusion: The allergen which is suspected to the patient from history-taking might be different with the result of patch test, so that performing patch testing is needed to investigate the cause of ACD.
