What Is Premna Serratifolia Root Extract?
Premna Serratifolia Root Extract is a plant based ingredient obtained from the roots of Premna serratifolia, a small evergreen shrub native to South and Southeast Asia. The roots are naturally rich in bioactive compounds such as flavonoids, phenolic acids, terpenoids and small amounts of essential oils, all of which contribute to its skin friendly profile. Long valued in traditional wellness practices, the plant was first used topically to calm and soothe the skin. As modern formulators began searching for botanical alternatives to synthetic conditioners, the extract gained popularity and found a place in contemporary cosmetic lines.
To make the extract, roots are cleaned, dried and milled into a fine powder, then steeped in a gentle food grade solvent like water or ethanol. The mixture is filtered to remove plant solids and the liquid is concentrated under low heat to preserve delicate compounds. The resulting extract is standardized for consistent quality before being added to finished products.
Because of its mild nature and conditioning properties, Premna Serratifolia Root Extract appears in a variety of leave on and rinse off formulas. You will commonly find it in daily moisturizers, soothing lotions, anti aging serums, hydrating masks and after sun gels where it supports smooth comfortable skin.

Comedogenic Rating
Rating: 1 / 5
Premna Serratifolia Root Extract is primarily composed of water-friendly compounds like flavonoids and sugars with only trace amounts of oil. These light molecules do not sit in pores or form heavy films, which keeps the risk of clogging very low.
With this low score the extract is generally fine for acne-prone or breakout-prone skin.
As always the overall formula matters, so a product packed with heavy butters could still trigger congestion even if this single ingredient would not.
