Although there are thousands of exfoliation methods on the market, only few of them are truly effective.
I tend to stay away from the products with microbeads. Why? I have never found them very effective in the first place, but what really confirmed my dislike of them was the sentence I once read: "What do you think happens to all those microbeads which are washed down your drain?"
Most exfoliation products contain plastic beads. Those go down the drain, into our water system, finish up in oceans. Apparently ocean fish all contain microbeads in their digestive system and in their tissue.
