What Is Ajuga Nipponensis Leaf/Stem Extract?
Ajuga nipponensis is a hardy herb in the mint family that grows across East Asia. The leaf and stem extract is packed with plant sugars, polyphenols, flavonoids and small amounts of essential oils that give it both water-loving and skin-soothing properties. Traditional folk remedies valued the plant for calming the skin, which led formulators to explore it for modern beauty products in the late 20th century when natural actives started gaining popularity.
To create the cosmetic grade extract, freshly harvested leaves and stems are gently dried then steeped in a mix of water and food-grade solvents. The liquid is filtered, concentrated and standardized so each batch offers consistent moisture-binding and conditioning performance. The finished ingredient is a clear to pale amber fluid that blends easily with both water-based and emulsion systems.
Today you will most often see Ajuga nipponensis leaf/stem extract in hydrating toners, lightweight lotions, sheet masks, soothing after-sun gels, anti-aging serums and occasional scalp treatments where extra moisture and comfort are desired.

Comedogenic Rating
Rating: 0–1 (very low)
Ajuga Nipponensis Leaf/Stem Extract is mostly made of water soluble plant sugars and polyphenols with almost no heavy oils or waxes. Because it sits lightly on the skin and rinses away easily it is very unlikely to clog pores. For this reason it is generally considered safe for people who are prone to acne or breakouts.
Only when a formula pairs the extract with richer emollients could the overall product feel heavier so always look at the full ingredient list if congestion is a worry.
Summary
Ajuga Nipponensis Leaf/Stem Extract acts as a humectant and skin conditioner. The natural sugars pull moisture into the skin keeping it plump while gentle phytochemicals smooth rough spots and leave a soft finish.
