help! what is this :(

My poor baby girl is only about 3 weeks old and her beautiful face is starting to break out. Her whole chin is raw looking... is this baby acne? Or something else? Any advice on how to help it? Or do I just leave it be? It breaks my heart looking at it.. but it doesn't seem to be bothering her. I wipe with a warm cloth after feedings but I feel like it's gradually getting worse not better..:(
