What it is
An extract derived from the flowers of Helianthemum nummularium, a plant commonly known as rock rose or sunrose. It contains various bioactive compounds, including flavonoids and phenolic acids, which contribute to its antioxidant activity.
How it works
The flavonoids and other polyphenols in rock rose flower extract help neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. By donating electrons to these free radicals, the extract helps prevent oxidative stress and supports the skin's natural defense mechanisms.
Pros
Gentle antioxidant
Provides a mild protective effect against free radicals without irritating the skin, making it suitable for sensitive skin types.
Soothing potential
May help calm redness or irritation, adding a soothing benefit to formulations alongside its antioxidant role.
Cons and cautions
Limited research
There is very little published scientific evidence specifically on Helianthemum nummularium extract in skincare, so its benefits are less established than those of more common antioxidants.
Lower potency
Compared to well-studied antioxidants like vitamin C or ferulic acid, this extract may offer weaker protection, so it's best used as a supporting ingredient rather than a primary active.
Best for
- Anyone looking for a mild antioxidant ingredient
- People with sensitive or reactive skin who want gentle protection
Use caution if
- Those seeking a proven, high-potency antioxidant with strong clinical backing
Usage tips
