AMORPHOPHALLUS KONJAC ROOT EXTRACT: what it is

Amorphophallus Konjac Root Extract, often called konjac root extract, is obtained from the roots of Amorphophallus konjac, a plant species in the Araceae family. That is the plant material identified on the label; it is not a fragrance or a mineral ingredient with a similar-sounding name.

Konjac is also known for konjac glucomannan, a purified polysaccharide obtained from the plant's tubers. The names should not be treated as interchangeable: a root extract and a purified polymer can differ in composition and in how they behave in a cosmetic formula.

AMORPHOPHALLUS KONJAC ROOT EXTRACT: what it does in cosmetics

In cosmetics, Amorphophallus Konjac Root Extract can serve as a humectant and film-forming ingredient. As a humectant, it helps retain water in the preparation; as a film former, it can leave a thin layer on the applied surface. In everyday use, those properties may contribute to the feel of a product on skin or hair.

The literature located for konjac glucomannan discusses gel and film-forming properties, but it is not clinical evidence for this root extract in a cream or serum. Studies involving food, supplements, modified materials, or delivery systems do not show that the isolated ingredient treats skin concerns.
