Science
Mechanism of Action
This ingredient works through a complex array of bioactive compounds, including vitamins (notably vitamin C), carotenoids, and a diverse profile of polyphenols such as flavonoids (rutin, quercetin, kaempferol, anthocyanins) and phenolic acids. These constituents collectively contribute to potent antioxidant and anti-inflammatory effects. Furthermore, it aids in skin cleansing by gently loosening dead skin cells, which supports the achievement of a more uniform complexion and overall skin refreshment.

Dusting Analysis
The CIR Expert Panel noted that Rosa Canina Flower Powder was 'not reported to be in current use' at the time of their 2016/2017 assessment. This absence of reported usage concentration suggests that if incorporated into formulations, it may be at sub-optimal or 'dusting' levels, as specific efficacy data for the powder form is currently undefined.
The Formula
Formulation
Stability
The solubility of Rosa Canina Flower Powder is complex, with anthocyanins exhibiting water solubility and essential oils from petals, largely composed of aliphatic hydrocarbons, suggesting oil solubility for certain components. The precise overall solubility will vary based on the specific composition and processing methods of the powder.
Safety
Safety Profile
The CIR Expert Panel deemed Rosa Canina Flower Powder, within a group of 12 Rosa canina-derived ingredients, safe for cosmetic use when formulated to be non-irritating and non-sensitizing. However, no specific maximum use concentration for the powder form was evaluated due to its lack of reported current use at the time of assessment. Formulators should account for cumulative botanical constituent levels when combining multiple plant extracts. Trace levels of heavy metals (< 2 ppm) have been observed in Rosa canina fruit extract, a general consideration for plant-derived ingredients.

Verdict
Rosa Canina Flower Powder is a valuable botanical offering broad skin conditioning, antioxidant, and anti-inflammatory benefits, though further research into optimal concentrations for its powder form is warranted for maximum efficacy.
