The boscia Konjac Cleansing Sponge. I Love this thing! Made of konjac root which has been part of Japanese beauty rituals for over 1,500 years. I bought mine at Sephora but similar sponges are available on Amazon. To use, wet the sponge, put a little cleaning gel on it and wash your face. It gently cleanses and exfoliates, and lasts two to three months. Plus, it makes washing my face a little more fun. Can’t argue with that.
