zero therapy causing chapped lips

i’m in the middle of a flare-up right now and am trying to commit to zero-ish therapy (washing with cetaphil when particularly oily/after exercising and using metro gel 2x daily). the PoD seems to not be spreading anymore which is great, but since i’ve stopped using lip balm my lips are dry and cracking to the point of bleeding.

i’m constantly uncomfortable and have 6 more days until i can get in with the GP to hopefully get oral antibiotics to go along with the metro gel. other than putting cold cucumber slices on my lips a few times a day for temporary relief, are there any lip balms/moisturizers that can help without making the PoD worse? i’ve been using vaseline for years but that’s obviously a no-no right now.
