Ophiopogon Japonicus Root Extract description

_Ophiopogon japonicus_ root extract is from a perennial evergreen plant native to southeast Asia, where is has a long history of various uses in the practice of Chinese Medicine. Research on the root of this plant has revealed it’s a rich source of a type of antioxidant known as homoisoflavonoids. Over a dozen have been identified in this plant, with two being especially good at reducing signs of irritation due to their pronounced soothing effect. This is complemented by the root’s saponin content, which are sources of carbohydrates in this plant. Along with calming signs of irritation, _Ophiopogon japonicus_ root extract also helps to visibly strengthen skin’s barrier by boosting a key ingredient (urea) in skin’s surface layers that’s part of its natural moisturizing factors. Doing so helps prevent water loss and maintain adequate hydration, as does the root’s mix of complex sugars known as polysaccharides. Usage levels of _Ophiopogon japonicus_ root extract as a blend with butylene glycol ranges from 1–5%. As you may have gathered, this plant extract has particular value for those with sensitive skin.
