A Japanese Skin Care Secret: Konjac

Konjac is a potato-like plant and is a traditional food, unique to Japan. Though once a delicacy, Japanese people now eat konjac daily as it is a low-calorie, high-fiber food that is known for improving gut health.

It is said that konjac was introduced to Japan as shojin cuisine, or vegetarian food for Buddhist monks. Over time, people grew their own konjac potatoes in their own fields. They processed them by hand, producing only enough for their families. 

What was not eaten was repeatedly frozen and dried by hanging it outside for a few days during the harsh winter season. After this process, only konjac fibers remained.

Japanese Skin Care

These ancestors used the remaining fibers to make konjac sponges. In a time when clothing was not gentle, parents wanted to wash their newborn children comfortably and safely. The konjac sponge – now a Japanese skin care tradition – was born from parental love.

Konjac has unparalleled water retention, moisturizing power, and elasticity. Additionally, it is a colorless and odorless vegetable fiber. This makes it an essential element in skincare and allows for a wide range of development. It is no wonder that this versatile plant has become a Japanese skin care staple. Today, demand has grown for this best-kept Japanese skin care secret to be shared around the world.

Japanese Skin Care

Authentic konjac sponges that have been used as part of a Japanese skin care regimen for generations are manufactured using only konjac. Konjac sponges are popular among those with sensitive skin. To remove dirt without irritating skin, our sponges are slightly alkaline with a pH of 8.0 to 9.0. When you use our konjac sponge to gently wash your face, the soft 100% natural fibers and the water film will gently remove dirt without damaging your skin.

Methylisothiazolinone is an antibacterial agent that is banned for use in products, such as cosmetics, that remain on the skin.
