My skin is beautiful everywhere BUT MY FEET! On the bottom of each foot is hard, dry, YELLOWISH skin in some places (i.e. ball of foot and heel ). On the sides of my feet, are dark, brown blotches similar to how acne can blemish a face. There are also certain pressure points (my guess is from the shoe rubbing the foot) that has small blisters filled with clear liquid. I moisturize my feet twice daily with Eucerin or Gold Bond Dry Skin or Burt s Bees but nothing seemd to work long term. Any advise will be appreciated.
