Using these facial sponges is a breeze. First, wet the sponge with warm water. Once it expands, you can gently use it on your face for cleansing or applying products. Since they're for single use, just toss them away after one application to keep things hygienic. There's no need for any special maintenance, but make sure to store them in a dry place. Avoid using them on broken or irritated skin. And that's it - enjoy the precision and natural goodness of these raindrop-shaped sponges!
