Korea is a hotbed of beauty trends and The Doctors are checking out some Korean Konjac sponges. These are derived from the root of a plant found in Asia. They are natural exfoliating sponges and they are a buzz! Dermatologist Dr. Sonia Batra says they need to be soaked first but once they are, they are the right amount of exfoliation. They aren’t too harsh that they will cause inflammation or irritation but they are ideal for sluffing off dry, dull skin.
