A fragrant geranium oil with mild astringent benefits, but its strong scent and potential for irritation mean it's best for those without sensitive skin.
In plain English
This is an essential oil made from the flowers, leaves, and stems of a specific type of geranium plant called Geranium macrorrhizum. In skincare, it's mainly used for its pleasant, rosy scent and its ability to help tighten pores and balance oil production.

emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
An essential oil steam-distilled from the aerial parts (flower, leaf, stem) of Geranium macrorrhizum, a perennial geranium species native to the Balkans. It contains aromatic compounds like citronellol and geraniol, which give it its characteristic scent and mild astringent properties.
How it works
When applied to the skin, the oil's astringent compounds can temporarily tighten the skin's surface and help reduce the appearance of pores. Its fragrance also provides a sensory benefit, which can make a product feel more luxurious. However, these same compounds can also disrupt the skin's natural barrier if used in high concentrations or on sensitive skin.
Pros
Natural astringent effect
Can help tighten pores and reduce shine for oily skin types, offering a quick matte finish.
Pleasant natural fragrance
Provides a rose-like scent that can enhance the sensory experience of your skincare routine without synthetic perfumes.
Cons and cautions
Potential skin irritation
Essential oils like this one contain volatile compounds that can cause redness, stinging, or allergic reactions, especially on sensitive or compromised skin.
Limited research on benefits
Most evidence for its astringent and soothing effects is anecdotal or based on traditional use, with few modern clinical studies to back up claims.
Best for
- People with normal to oily skin looking for a natural astringent
- Those who enjoy botanical fragrances in their skincare
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Anyone with a known allergy to essential oils or fragrance components
