Does anyone ever have allergic reaction using Curaderm? My husband put it on his squamous cell skin cancer spot. He then went out for an activity outdoor late in the afternoon. He developed rough scales and rash and tiny lumps on his chin and forehead. He believes he had reactions to Curaderm and wants to stop using it. Is it a normal reaction? Should he continue or stop? We contacted Curaderm but nobody replied. Thank you!
