As usual with EC, some may work for others and some won't. I have not heard of anyone trying to manage EC with Blistex or maybe I just haven't read enough.
About Aquaphor, some users find it helpful and some find it made their lips worse by a margin.
I've actually had this for around 4-6 months now, but I can definitely say it has drastically worsened just this Feb because my upper lip wasn't peeling a month ago and doesn't get white in water, but now it kinda does too.
