I have been using this since a young woman, And u do have to put it on thick to remove the hair, Leave it on for a good 15-20 minutes, I personally use a regular razor to shave it off ! Ur legs will be grateful to u, No hair for 2-3 weeks! It used to smell of bleach n Hydrogen peroxide n not anymore, U still smell a hint of it still, but now this one particular one it smells of flowers too! I recommend u have shirts on or a very short top on , no pants it will be like bleach,bleach your pants.
