Abstract
A 64-year-old female presented with facial hyperpigmentation. She had dyed her hair monthly with pure henna powder for the past seven months. After patch tests, the patient was diagnosed as post-inflammatory hyperpigmentastion due to allergic contact dermatitis to pure henna that has rarely been reported. The patient underwent Q-switched Nd:YAG laser treatment and was treated with oral tranexamic acid for 10 weeks. The hyperpigmentation on her forehead demonstrated substantial improvement.
