I splattered a drop of concentrated phenol:chloroform solution while performing DNA extraction on my hand. Initially, I didn't feel anything and then I noticed a white substance forming on my skin where the phenol had made contact with. Then I felt a slight burning sensation. I immediately washed my hands with water, and the burning sensation slowly disappeared. However, I noticed that a small area of my skin has turned purple, like when you accidentally burn your skin while handling hot items or accidentally flaming your skin.The scar doesnt appear too bad but I just wanted to know if such a burn scar caused by a chemical is permanent? Please help.
