Potato pack – The best home remedy: Find small to medium sized potatoes when you next go for vegetable shopping. Peel away the skin and make a paste of the potato in a blender. The paste you get might be watery. Don’t try to filter the water out. Use the paste as such. Apply generously all over the arms and face. Let it dry (I hate the raw smell – but the result is worthy enough). Allow it to dry well and then wash it off with plain cold water.
