Impetigo in toddler

Dominique

Back in may my son had a few spots of impetigo from daycare. Had him on antibiotics and cream . Went away . He now has it again all over his face . The doctor doesn’t want to do antibiotics yet . Anyone have home remedies I can use on a toddlers face.?

What I found on google was to use bleach in his bath water but I don’t feel like that’s safe especially since the affected area is his face
