When Jose Vega Aquino of Puerto Rico started using a popular cream to treat his acne, instead of seeing an improvement in his skin, his face became inflamed with red, sore pimples.
"There was itching, dryness and redness," Aquino said. "Any gesture, even a laugh, was very painful."
He discontinued using the acne treatment but the redness and pain persisted. "I stopped using my contacts and tried to hide behind my glasses. I felt terrible," he said.
