Centella Asiatica Extract

Korea ranking #43 serumUS stock

A pared-down formula that is essentially centella asiatica (cica) extract in a light, watery base, with no fragrance and no added extras. It feels like a thin toner or essence and is meant to calm skin that runs sensitive, red, or easily irritated. Simple enough to slot into almost any routine, on its own or layered with other steps.

More detail

The formula is about 95% centella asiatica extract, a botanical valued for soothing irritation, calming redness, and supporting the skin barrier, rounded out only by butylene glycol and a gentle preservative, with no fragrance, essential oils, or alcohol. The texture is thin and lightly slippery, absorbing like a hydrating toner. Use it after cleansing by patting a few drops into the skin, or layer and mix it with your other products; morning and night both work. Its minimal ingredient list makes it a low-risk choice for reactive skin. As with any concentrated botanical, patch test first if your skin is highly sensitive.
