I never leave the same barrier on for more than a day, I'll always wash it off gently and reapply - I managed to go quite long with that routine before I messed it up for other reasons. But keeping the same barrier for me is not possible because the layers build up far too much and interfere with daily life a lot.
I'm happy someone else (you) is trying a different method though. We know the product is effective but we need to determine the best methodology of applying.
If more people who read this thread tried it we could explore even more application methods.
Most important thing is to keep updating on your methodology and progress here, if you find anything that hinders progress let us know. Any tweaks to your application regime that help let us know, and I'll do the same.
