The skin is the largest organ of the human body, and yet it's something we tend to take for granted. It really does pay in the long run to take care of it, which anyone in the know will confirm — I mean, who has ever reached a ripe old age and thought to themselves, “I wish I hadn't wasted all that time taking care of my skin”?

Exfoliation is an important aspect of any skincare routine, and these sponges from Minamul are a fantastic tool for getting the job done.

Made from natural and biodegradable konjac — a porous root vegetable said to have been first used by Japanese farmers centuries ago to cleanse babies' skin — these sponges exfoliate really, really gently, making them ideal for daily use even if you have sensitive skin or tend to suffer irritation from scrubs and the like.

They're also infused with activated bamboo charcoal, which binds with impurities on a molecular level and thus deep-cleanses your pores and reduces excess oil, with the added bonus of being anti-microbial so the sponge doesn't become home to lingering bacteria and odors, the way those crappy plastic dollar-store loofa puffs do.

When you're done with a given sponge — which can take a couple weeks or a month, depending on your usage — simply toss it in your compost.

Pick up a pack of 4 body sponges ($14) or 6 facial sponges ($10) and give your skin that glowy boost it deserves.
