Ingredient review
Krameria Root Extract
INCI: Krameria Cistoides Root Extract
A gentle botanical astringent that may help tighten pores and calm skin, but research is limited.
In plain English
Krameria root extract comes from a shrub native to South America. In skincare, it works as a mild astringent, meaning it can help tighten the skin's surface and temporarily reduce the appearance of pores. It also has soothing properties, making it a nice addition for sensitive or oily skin types. However, there isn't much scientific research on this specific extract, so most of what we know comes from traditional use and a few lab studies.

What it is
Krameria root extract is a natural ingredient derived from the roots of the Krameria cistoides plant, also known as rhatany. It contains tannins and other polyphenolic compounds that give it astringent and antioxidant properties.
How it works
The tannins in krameria root extract bind to proteins in the skin's outer layer, causing a mild tightening effect that can temporarily reduce pore visibility. This astringent action also helps remove excess oil from the skin's surface. Additionally, the polyphenols may provide antioxidant protection against environmental stressors.
Pros
Gentle pore-tightening effect
Unlike harsh astringents like alcohol, krameria root extract provides a mild tightening sensation that can temporarily reduce the look of pores without stripping the skin.
Natural antioxidant source
The polyphenols in this extract may help neutralize free radicals from pollution and UV exposure, offering a low-level protective benefit.
Cons and cautions
Limited research backing
Most evidence for krameria root extract comes from traditional use and a handful of lab studies, so its benefits are not as well-documented as more studied ingredients like niacinamide or green tea.
Potential for dryness
Because of its astringent properties, using products with a high concentration of this extract may leave dry or sensitive skin feeling tight or irritated.
Best for
- People with oily or combination skin looking for a gentle astringent
- Those who prefer natural botanical ingredients in their routine
Use caution if
- Individuals with very dry, sensitive, or eczema-prone skin may find it too drying
Usage tips
Safety summary
