But before applying any product or lotion, in Allumidermorder for the final result to be as expected it is necessary to prepare the skin properly. We advise you to wash with warm water and a mild soap the area to be whitened and then exfoliate to remove all dead cells and get the skin ready to absorb the nutrients from the lightening ingredient you are going to use. The exfoliation can be done with a commercial lotion or with some basic products you have at home, such as salt, sugar, coffee or oats.
