These little rock-like sponges have taken the skincare world by surprise, and for a good reason. They’re made out of a root called konjac, hence the name. This root has been part of Asian cultures for thousands of years.

As a matter of fact, konjac sponges were first used on babies in Japan, Korea, and Southeast Asia, about a century ago. The reason they became so popular is that once they’re soaked in water, their texture becomes so soft that is ideal to cleanse delicate skin while also providing an extremely gentle exfoliation.

The science behind konjac sponges is relatively easy. The konjac root powder is melted along with calcium hydroxide. Once the mix has cooled down, it turns into the compact rock-like form we know. In most cases, the original mix is enhanced with other components such as activated charcoal, or different types of clays.

Why They Work

We all know about the importance of exfoliation when it comes to skincare. It helps to remove toxins and dead cells, as well as improve blood circulation. Konjac sponges are great for daily exfoliation because they’re so soft they won’t irritate skin. In the long run, you will notice softer and more luminous skin.

They’re also extremely useful if you have flaky or acne-prone skin. Konjac sponges are great even for sunburnt skin and eczema. Besides, the konjac root is rich in minerals and vitamins (A, B, C, D, and E) that are great for your skin.

One Color For Every Need

Like I mentioned before, it is common to find konjac sponges with added benefits. As a result of these additional ingredients, there’s a wide variety of colors. These are the most common:


This is the natural color of the konjac sponge without any added ingredients. Let’s say, the classic version.


Black sponges contain activated charcoal. As you may know, charcoal has become very popular in skincare because its great for removing impurities that cause blackheads and acne.


Most green sponges contain green clay, which is great to mattify and purify skin. However, there are others that contain green tea, which helps treat acne and prevent the early signs of age. 


Red konjacs are enriched with red clay which has astringent and exfoliating properties, ideal for oily and combination skin types. This is a very popular one for acne-prone skin to keep pores unclogged and prevent breakouts. 


Purple sponges are less common but are the first kind I tried. They contain lavender, which is known for its soothing and relaxing properties.

How to Use Them

When you use a konjac sponge for the first time, you will have to soak it in warm water for a few minutes. You will notice how it starts to expand and becomes really soft, almost slimy. Press to remove the excess and water and proceed to wash your face in circular motions.

Once you’re done, pat the sponge with a dry towel. Just make sure you don’t press too hard because you might damage it. Hang the sponge in a well-ventilated spot so it can dry completely. This is very important to prevent it from growing mold. You can also wash it with boiling water every two weeks, just to make sure it stays clean.

Depending on how much you take care of it, a konjac sponge can be used from 4 to 6 weeks. Once you notice it starts to break, it’s time to change it. 

Sustainable Beauty

One of the things I liked the most about konjac sponges is that they’re completely degradable. Hence, you can toss it into the organic trash, or even your compost pile. Pretty cool, huh?
