Ingredient review
Rue Leaf/Stem Extract
INCI: RUTA GRAVEOLENS LEAF/STEM EXTRACT
Rue extract may offer astringent and soothing benefits, but its use is limited by potential skin irritation and lack of robust safety data.
In plain English
Rue leaf/stem extract comes from a plant called common rue (Ruta graveolens). In skincare, it's used mainly for its astringent properties, which means it can help tighten pores and reduce oiliness. Some people also find it calming for minor skin irritations. However, rue contains compounds that can make skin more sensitive to sunlight and may cause irritation in some individuals, so it's not as widely used as gentler botanical extracts.

What it is
Rue leaf/stem extract is a natural ingredient derived from the leaves and stems of the Ruta graveolens plant, a perennial herb native to the Mediterranean region. The extract contains various bioactive compounds, including alkaloids, flavonoids, and essential oils, which contribute to its astringent and soothing effects.
How it works
In cosmetic products, rue extract works primarily as an astringent by causing mild contraction of skin cells, which can temporarily tighten pores and reduce the appearance of oiliness. Its flavonoids may also provide antioxidant and soothing benefits, helping to calm minor redness or irritation. However, the exact mechanisms are not fully understood, and its effects are generally mild compared to more researched ingredients.
Pros
Natural astringent
Rue extract can help tighten pores and reduce excess oil, making it useful for oily skin types in toners or mists.
Antioxidant content
Contains flavonoids that may help neutralize free radicals, offering some protection against environmental damage.
Cons and cautions
Irritation risk
Rue extract can cause skin irritation, redness, or allergic reactions, especially in sensitive skin, limiting its suitability for many users.
Photosensitivity concern
Compounds in rue may increase sensitivity to UV light, raising the risk of sunburn if used without adequate sun protection.
Best for
- People with oily or combination skin looking for a natural astringent
- Those who tolerate botanical extracts well and want a mild soothing ingredient
Use caution if
- Individuals with sensitive or reactive skin
- Anyone with a history of allergic reactions to rue or related plants (citrus family)
Usage tips
Safety summary
Rue extract is considered safe for cosmetic use at low concentrations, but it carries a moderate risk of skin irritation and photosensitivity. It is not recommended for sensitive skin or for use without sun protection. Always patch test and consult a dermatologist if you have concerns.
Research notes
Research on rue extract in cosmetics is limited. Most evidence comes from traditional use and in vitro studies showing antioxidant and antimicrobial activity. Human studies on safety and efficacy are scarce, so its benefits are not well-established compared to more studied botanicals.
Common label clues
- Typical concentration
- Typically used at 0.1–1% in leave-on products
- Regulatory status
- Approved for cosmetic use in the EU and US, but concentrations are typically restricted due to potential irritation and phototoxicity. Not recommended for leave-on products at high levels.
- Common uses
- Toners, Facial mists, Soothing serums
- Environmental note
- Rue is a hardy perennial that can be grown in dry, rocky soils, making it relatively sustainable to cultivate, though wild harvesting should be avoided to protect natural populations.
Good to know
- Rue has a long history in traditional medicine, but its use in modern cosmetics is limited due to safety concerns.
- The plant is also known as 'herb of grace' and has been used in folk remedies for centuries.
