Ophiopogon Japonicus Root Extract

Ophiopogon Japonicus Root Extract is a botanical humectant/soothing extract (often used around ~0.1–2%) with limited evidence of intrinsic irritancy and is generally well tolerated in leave-on moisturizers. However, as a plant-derived mixture it carries a small but real risk of idiosyncratic irritation or sensitization in highly reactive/eczema-prone patients, so it is best scored as very gentle rather than inert. Safety Notes: In mass-market and prestige leave-on products (toners/essences/serums/creams), Ophiopogon Japonicus Root Extract is frequently used as a secondary botanical at very low levels (often ~0.0005–0.05%) due to supplier-recommended use rates and INCI-list positioning. Higher-end soothing/barrier-focused serums and ampoules—especially Asian beauty products marketed around "Mai Men Dong" hydration—are formulated closer to typical botanical active levels (~0.5–2%), and a small number of high-strength consumer products use up to ~5% when the extract is the primary featured active. Rinse-off cleansers/masks generally sit toward the low end because of short contact time, while leave-on formats account for most of the upper-range usages.
