Konjac (glucomannan) is a vegetable with unique properties. Konjac when moistened, has an almost gel-like feel. The Konjac plant is naturally alkaline, making it very gentle for the skin. Konjac sponges are extremely gentle, and will remove dead skin cells, debris, and makeup. Konjac sponges are 100% biodegradable, so please compost your sponge when you are finished with it. Sponges should be replaced from 6-8 weeks after usage. We offer a pure Konjac sponge for all skin types and one infused with cleansing charcoal, recommended for acne prone skin. Konjac sponges can safely be used every time you wash your face.
