How did the lime get on the face?
Is calces, immediately with oil (other oil - such as horse oil) to clean the lime, and then washed with water, because the lime water will react and produce high calorie burning skin, and lime is a strong alkaline substances will damage the skin, and can be isolated from oil water and avoid reaction.
It's slaked lime, it doesn't react with water, but it still damages the skin because it's strong alkaline, so it should be washed immediately.
In this way, not only does not hurt the skin, but on the skin surface played a bactericidal role. Ha-ha
