I am on here looking for an in-home cure for water blisters. My daughter presented her hand to me & it is covered in water blisters, i took her to our doctor & she diagnosed her with scabies which she doesnt have. I know that these are not part of the Excema family, & i know this because i have Excema myself & i have had Excema all my life & never seen water blisters as part of it. If anyone out there is looking for something to help with the Excema then i have something for you to consider as i do this myself & yes it does work.
Add 2 caps of either Janola or Bleach with 2 squirts of Protext anti-bacterial handwash soap (has to be in the hand pump bottle though). Soak for atleast 30mins, it will dry your skin, but for me & a few other people that i have told it helps us, but i will stress that this is not for everyone but in life everything is worth a try atleast once. If it doesnt work then you know but if it does its a very inexpensive way to help fight off the infection. You can use this for any skin condition. I got this information from a friend of mine who got it from a Excema nurse for her son, so give it a whirl & see how you go.
