Ingredient review
Croton Glabellus Bark Extract
INCI: Croton Glabellus Bark Extract
A gentle botanical extract with antioxidant potential, but research is limited and benefits are not yet well-established.
In plain English
Croton Glabellus Bark Extract comes from the bark of a tree native to South America. In skincare, it is added for its ability to fight free radicals (unstable molecules that can damage skin) and to help calm the skin. However, there isn't much scientific research on how well it works compared to more studied ingredients like vitamin C or green tea.

What it is
Croton Glabellus Bark Extract is a natural extract obtained from the bark of the Croton glabellus tree, a plant in the Euphorbiaceae family. It contains various plant compounds, including flavonoids and tannins, which are thought to provide antioxidant and anti-inflammatory benefits.
How it works
The extract works primarily by donating electrons to neutralize free radicals, which can otherwise cause oxidative stress and contribute to premature skin aging. Its tannins may also have a mild astringent effect, helping to tighten pores and reduce excess oil on the skin's surface.
Pros
Natural antioxidant source
Derived from a plant bark, it offers a natural way to introduce antioxidant protection into your routine, potentially helping to defend against pollution and UV-induced free radicals.
Low irritation potential
Based on available data, it appears to be gentle on skin with a low risk of irritation or clogging pores, making it suitable for many skin types.
Cons and cautions
Limited research
There are very few peer-reviewed studies on Croton Glabellus Bark Extract specifically in cosmetic applications, so its efficacy and long-term benefits are not well understood.
Uncertain concentration guidelines
Without robust safety data, it's unclear what the optimal or maximum safe concentration is in leave-on products, which can vary by formulation.
Best for
- People looking for a gentle, natural antioxidant ingredient
- Those with normal to oily skin who want a mild astringent effect
Use caution if
- Individuals with known allergies to plants in the Euphorbiaceae family (e.g., poinsettia, castor oil plant)
