Hi, hot oil splattered on my arm and my first instinct was to put ice. After googling I realized this was a mistake. Ran my arm under cool water for a while. From photos can you please tell me, is this a first or second degree Burn? It looks like blisters will form. I wanted to apply burnol but it says do not use for second degree burns. I also have burnheal which has silver nitrate and chlorhexidine gluconate cream. Which one should I use? Thanks.
