My daughter is allergic to Mastisol. She began using Banana

Customer Question

My daughter is allergic to Mastisol. She began using Banana Boat Sunscreen Lip Balm, 45 SPF, beginning Thursday, 4/21, while at a 4 day music festival. Used it daily, by Sunday, 4/25, her lips became swollen, red with oozing blisters. Symptoms and appearance are identical to her past Mastisol reactions. How can we determine what chemical, ingredient causes these reactions? Thank you!

She should see a dermatologist or an allergy specialist to have a skin prick test for the chemicals and ingredients.
