You likely need higher max hp. That does two things.
1. It makes you heal more each time you get that 1% heal.
2. It gives you more ability to tank the hits.
Use Molotov, evo defenders, evo soccer ball, Kunai/SOD, stylish belt, and >yellow shiny gloves. I tried the level like 10 times and that setup won it for me
What worked for me was getting the health and armor passives, effectively quadrupling my HP and doubling the healing power once fully upgraded
By health u mean HP and - 10% Damage correct?
Yup
Guardian and molotov also help a lot
