Welcome to the party!
Make sure you check out the free aquaphor thread. That one is a lifesaver when you're going through a $17 jar every week.
Unfortunately, try it and see is the best advice we can give. With 30 different types of ichthyosis, many of us are dealing with opposite problems. Netherton's skin is too thin. EHK blisters all over the place, LI leaves a trail of flakes and eye problems. XLI has the pregnancy issues as well as the skin issues, and IV folks are often told they have something that isn't even ichthyosis so end up stumbling upon us blindly.
The only stuff that's really in common is that we all have water barrier problems - lots of dehydration and overheating issues, and generally keeping the skin soft so it doesn't dry and crack. The majority of us do long baths, lots of scrubbing, add bleach to the bathwater to kill the bacteria, and find some cream or other that works for them. Beyond that, we pretty much just make it up as we go along.
Another thing you might want to look into is the FIRST foundation. They hold a family conference at the end of June every even year. Next year's will be in Denver. It is SOOOO worth it to come and spend the weekend and meet people of all ages that have been there and done that and can often answer whatever you want to know.
