Hi, It is not advisable to use kerosene or any other harsh agents or chemicals on the skin. Some colours, especially the dye based ones, stain the skin deep and stay on for some time. Use only your routine soap which is gentle and suits you. Don't rub too harshly. It will take a few days for the color to fade. Keep your skin hydrated with a good moisturizer. Give it time. Be patient. Take care, Dr Siddharth Prakash
