Our Luna Charcoal Facial Sponge is made from the roots of the konyakku plant and infused with charcoal. The sponge is ideal for daily use, especially for sensitive and acne-prone skin. For the first use, soak the sponge in warm water for 10-15 minutes until it puffs up and rehydrates. It expands about 50% and will be squishy. To use, soak briefly in warm water and rub in circular motions to clean pores. Press between palms to remove excess water and hang to dry. Lasts up to 6 months.
