Ophiopogon japonicus root extract: properties, uses, pros, cons, safety
Description
Ophiopogon japonicus root extract is obtained from the roots of Ophiopogon japonicus, a plant commonly known as mondo grass or dwarf lilyturf. The extract is widely used in cosmetic formulations for its moisturizing, soothing, and anti-inflammatory properties.
It is particularly suitable for products designed to improve skin hydration, reduce irritation and redness, and support the skin barrier function, contributing to overall skin comfort and well-being.

Chemical composition and structure
Ophiopogon japonicus root extract contains a combination of bioactive compounds with synergistic effects on the skin:
Saponins
Contribute to soothing and conditioning properties, promoting skin comfort.Polysaccharides
Play a key role in water retention, forming a protective film on the skin surface that helps prevent dehydration.Flavonoids
Provide antioxidant activity, helping protect the skin from oxidative damage induced by environmental stressors.Vitamins and minerals
Supply essential nutrients that support skin vitality and physiological function.
The overall chemical structure of the extract is complex and variable, depending on the extraction method and raw material; however, the combined presence of saponins, polysaccharides, and flavonoids is responsible for the main cosmetic effects.
| Compound class | Primary function |
|---|---|
| Saponins | Soothing, conditioning |
| Polysaccharides | Moisturizing, film-forming |
| Flavonoids | Antioxidant |
| Vitamins and minerals | Nutritional support |
