Sunken fontanelles (superior view). I have no experience with it, because Boston isn't sunny enough. I'm also not familair with the brand name you refer to.
The procedure does sound right, though you'll need to ask the doctors who prescribed it for details. Chances are they know what they're doing.
Good luck.
