Are you using stainless steel or plastic bowls. I found that when I used the plastic bowl Raven started getting some chin acne. Then I switched her to the stainless steel bowls and it went away. The stainless bowls get cleaned right after and before usage with very hot and soapy water. Her acne seems to be gone now. She does have some tear staining but I think in her case it's seasonal allergies. For now might I suggest you clean his face and his eyes with a good warm wash cloth and dry it well after he eats. Then if that doesn't work try one of the cleaners. The tear staining might have also kicked into over drive because you went to a different area. Not sure if you used bottled water or regular tap water, but water differs from region to region. Good luck. The simple change with the bowls and wiping her face with a warm wash cloth helped us.
