These sponges are like hard styrofoam when you get them. After a minute or so in warm water, the sponge will soften and expand. Just a little bit of soap and they suds up very nicely. Rince it out and hang to dry. The sponge should last 2-3 months with care. I think this charcoal one does dry my face a bit but I just use a honey moisturizer afterwards and my face is nice and soft. I really like this sponge but I think I might try the aloe one next time.
