He does not have entropion? If his eyes water, there is a reason. Could be an allergy to something in the air too, like flowers, grass, ect.
I recommend keeping him on the diet he is on, that is really GOOD food. It has a very high rating. Can you put baby powder in his wrinkles safely?
My bully Sarah had allergies so bad I actually had her ROPE wrinkle removed, so she would be more comfortable. Now I am not saying you have to do that! But it will depend on the severity.
If this guy is a bully vet, why has he not asked you to run allergy tests on her yet? The idea is not to MASK the problem, but to find the source of it! If he continues to have problems, I would look into that, and make sure there is no entropion! He could have a very mild case of it but it is still very uncomfortable and make the eyes water really badly!
