Japanese women have been using konjac sponges for 1,500 years to exfoliate their face every day! It can also help to relieve acne breakouts! One of the benefits of using a konjac facial sponge is its ability to remove dirt, oil, and dead skin cells from the skin's surface without causing any irritation. This is particularly important for those with sensitive skin, as they must be careful not to aggravate their skin with harsh chemicals or exfoliants. Made in Hubei, China, this province is a mountainous region with a warm, humid climate, making it ideal for growing konjac. To avoid using plastic packaging and preservatives, the sponge comes in its dry form.
