The redness drew widespread attention when news photographers captured close-up images of the president’s neck during a Medal of Honor ceremony. Here was the White House’s response:

“President Trump is using a very common cream on the right side of his neck, which is a preventative skin treatment, prescribed by the White House Doctor,” Sean Barbabella, the president’s doctor, said in a statement. “The President is using this treatment for one week, and the redness is expected to last for a few weeks.”
