On day 5 of the caveman regimen now. Only washed my face 4 times so far with just a splash of water. I have to say my face gets incredibly oily throughout the day and this is really annoying. I am also experiencing a very bad breakout af about 5 or 6 whiteheads. My skin has also gotten very rough in the areas of oily skin (forehead, nose, cheeks, chin). Hopefully this is the detox period and there are better days ahead!
