Ingredient review
Broom Flower Extract
INCI: Cytisus Scoparius Flower Extract
A gentle botanical extract with antioxidant potential, but research on its cosmetic benefits is still limited.
In plain English
Broom flower extract comes from the bright yellow flowers of the Scotch broom plant. In skincare, it's used mainly as an antioxidant to help protect skin from environmental stress, and it may have mild soothing effects. Because it's not heavily studied in cosmetics, it's considered a supporting ingredient rather than a star performer.

What it is
A natural extract derived from the flowers of Cytisus scoparius (Scotch broom), containing flavonoids and other plant compounds that can act as antioxidants.
How it works
The flavonoids in broom flower extract help neutralize free radicals, which are unstable molecules that can damage skin cells. This antioxidant action may help reduce oxidative stress on the skin, potentially supporting a more even-looking complexion over time.
Pros
Gentle antioxidant
Provides mild protection against environmental stressors without being harsh or irritating for most skin types.
Botanical appeal
Derived from a natural plant source, which appeals to consumers seeking plant-based skincare ingredients.
Cons and cautions
Limited research
There are few peer-reviewed studies specifically on broom flower extract in topical skincare, so its benefits are not as well-established as more common antioxidants.
Potential allergen
As a plant extract, it can cause allergic reactions in individuals sensitive to related plants, though this is rare.
Best for
- Anyone looking for gentle antioxidant support
- Those with normal to combination skin who enjoy botanical ingredients
Use caution if
- People with known allergies to plants in the Fabaceae (pea) family
- Those with very sensitive skin who prefer minimal ingredient lists
Usage tips
Safety summary
Broom flower extract is considered safe for topical cosmetic use at low concentrations. There is a low risk of irritation or allergy, but as with any botanical, individual sensitivity is possible.
Research notes
Research on broom flower extract in skincare is sparse. Most evidence comes from traditional use and general knowledge of its flavonoid content, rather than controlled clinical trials on skin.
Common label clues
- Typical concentration
- 0.1% to 1% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used at typical concentrations. Not a regulated drug ingredient.
- Common uses
- Serums, Moisturizers, Toning lotions
- Environmental note
- Scotch broom is an invasive species in parts of North America and Australia, so sustainable harvesting practices are important.
Good to know
- Broom flower extract is sometimes used in traditional herbal medicine, but cosmetic use is separate from medicinal use.
- The plant is considered invasive in some regions, so sourcing may vary.
