Ilex Rotunda Leaf Extract
INCI: Ilex Rotunda Leaf Extract
A gentle plant extract with antioxidant potential, but research is still early and benefits are not yet proven in human skin.
In plain English
Ilex rotunda leaf extract comes from the leaves of a holly tree native to East Asia. In skincare, it's added to help protect skin from environmental stress and calm minor irritation. Think of it as a mild, plant-based helper that may support your skin's natural defenses, though it's not a powerhouse ingredient on its own.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.

emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A water-soluble extract obtained from the leaves of Ilex rotunda, a species of holly. The leaves contain various plant compounds, including flavonoids and phenolic acids, which are thought to contribute to antioxidant activity.
How it works
In a cosmetic product, Ilex rotunda leaf extract is believed to work by donating electrons to neutralize free radicals (unstable molecules that can damage skin cells). It may also help reduce the production of certain inflammatory signals in skin cells, leading to a mild soothing effect. However, these mechanisms are based on laboratory studies and have not been confirmed in human skin.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for most skin types, including sensitive skin.
Natural antioxidant
Derived from a plant source, it offers a mild defense against free radicals from pollution and UV exposure.
Cons and cautions
Limited evidence
Most research is in test tubes or on animals; there are no robust human studies proving it visibly improves skin.
Low potency
Compared to well-studied antioxidants like vitamin C or niacinamide, its effects are likely weaker and less reliable.
Best for
- Anyone looking for a gentle, plant-based antioxidant in their routine
- Those with normal to combination skin who want extra environmental protection
Use caution if
- Individuals with known allergies to holly plants or related species
- Those seeking a proven, high-potency antioxidant (consider alternatives like vitamin C or ferulic acid)
