Price:  $11.95


A Konjac sponge is made from the Konjac plant native to East Asia. Its integral part in Traditional Chinese Medicine has been irreplaceable for over 1500 years, and more recently has evolved into the skincare industry as a natural exfoliant even for those with sensitivities. The vitamin-rich Konjac plant is what the sponge is made from – 100% natural vegetable fibres derived from the plant roots.  

It’s made from adding water to Konjac root powder, thickening it into a paste. The paste is mixed with a natural calcium hydroxide powder to make it alkaline, where then it’s heated, frozen and dried. Makers can add components to these sponges to create a more targeted product depending on the skin’s needs – this is why you’ll see different colours on offer. The added Green Clay in this Konjac sponge is rich in minerals and fine essential oils to restore vitality whilst drawing out any excess oil and impurities from the skin. 

This sponge is like a gentle, natural version of a Clarisonic – exfoliating the dead skin in circular motion with the same aftereffect without tiny bristles irritating the surface. As the sponges are natural, they need to be rinsed thoroughly and excess water squeezed out (not twisted). Leave them out to dry nowhere near the shower – this will avoid any moisture trapping back into the sponge. Once dried, they return hard. A general rule is that Konjac sponges should dry completely between uses. Usually, Konjac sponges last around 4-6 weeks.


Who are KUU Konjac?

KUU Konjac believe that the Konjac sponges are the most natural way to cleanse skin. The original use for these sponges were made for the delicate skin of babies, and have been adopted far and wide for anyone, with any skin type. KUU Konjac produce their sponges in one of the purest, most untouched areas in Korea – Jeju Island – an UNESCO World Heritage site. And by pure, we mean, this water is filtered through volcanic rockland producing some of the highest quality water in the world. This, coupled with the Konjac fibres, produce their high quality Konjac sponges.

All of KUU Konjac’s sponges are free from parabens, chemicals, preservatives, artificial fragrances and artificial colours. They are vegan and not tested on animals. The key difference between KUU Konjac sponges and others is that the quality of the fibre is high – meaning that in comparison to other manufacturers who may use artificial dyes in their sponges, KUU’s sponges last longer, where others will disintegrate within a few weeks of use. The best part about Konjac sponges? They are incredibly environmentally friendly and fully biodegradable.


First impressions

The KUU Konjac sponge doesn’t have any artificial fragrance in it, so it smells as bland as what you’d imagine fibre to smell like. It’s really not off-putting, as the texture and aftereffect is what’s more important here.

Konjac sponges are very hard in texture, almost like a pumice rock to begin with. They need to be softened with water, and gently massaged until the water has penetrated all the way through.

There is absolutely no harm in using Konjac sponges as part of your routine. You can use them solo for their purifying capabilities or with a cleanser for added cleansing properties. Due of the nature of the product, any skin type can benefit from using a Konjac sponge (ensuring that it is a high-quality sponge), particularly for sensitive skin types that struggle to pinpoint exactly what they’re sensitive to. Skin should feel cleansed but moisturised after use.

Formulation full analysis

The Good

100% Natural Konjac Fibres are extracted from the Konjac root. The root contains about 40% glucomannan which can expand up to 17 times in size when in contact with water, making it a natural hydrating product. It’s also been reported to have natural antibacterial properties which can help in combatting oily skin and reducing acne.

French Green Clay is a common addition to products when targeting normal to oily or acne-prone skin types. The reason is because French Green Clay contains valuable properties that naturally absorb excess oils and pulls bacteria to the surface of the skin. This is due to the iron oxide content and high amount of decomposed plant matter that has a multitude of mineral elements helping to refine and purify the skin.  

The Questionable

There are no questionable ingredients in this product.
