I wasn’t sure about this at first and did an internet search. Which I recommend. Easy to use. I drop in a glass of water while I make my coffee. Squeezing out the water and run under warm water while I gently rub all over my face. What’s wonderful about this sponge, is you don’t need cleanser. At night you may need a cleanser to remove makeup. Just remember to gently wash it and air dry. It shrinks as you use it.
