The Micro Exfoliator + 3 Minute Mask by Geologie is an incredible product, according to Lauren's video review. This versatile product can be used in three different ways - as a scrub on the face, as a mask for three minutes, or as a body scrub. Lauren also mentions the concept of skin cycling, where you can alternate between exfoliating and using Retin-A or Retinol. She highlights that the product smells great and has helped clear up her skin by getting rid of dead skin cells. Overall, Lauren seems very happy with the results of using this product.
