Dear Greta Harrison， Thank you very much for your inquiry．We are happy to help you with your questions． From the code you gave US，we have determined that your sunblock passed its expiration datethree months a90．This is the most likely reason why its consistency has changed． The product should retain its consistency at reasonable room temperatures，even in warm areas． Refrigeration will not restore it to the original consistency．Given the expiration，the active ingredients in the sunblock have lost effectiveness． We would be happy to replace the product．However，we will need your full contact information before processing this．Please call(888)195-3958，extension l l2，with reference number 153206 to provide the information． Please feel free to contact US again with any questions． Bradley MartinCustomer Service Representative Guarderma Skin Care
