Science
Mechanism of Action
This extract functions through a complex synergy of active compounds, including phenolic compounds like flavonoids and tannins, alongside Vitamin C. These components confer potent antioxidant properties, neutralizing free radicals and reinforcing the skin barrier. Its anti-inflammatory capabilities reduce redness and calm irritated skin. Emollient properties provide hydration and nourishment, while astringent qualities help refine pores and promote a balanced complexion. Furthermore, it exhibits antibacterial activity. Critically, studies have demonstrated its anti-aging prowess by inhibiting key enzymes such as collagenase, elastase, hyaluronidase, and tyrosinase, which are crucial for maintaining skin's youthfulness and even tone.

Key findings
- 01 Rosa floribunda nanoparticles (RcNps) significantly reduced xanthine oxidase activity, indicating antioxidant properties. RcNps also demonstrated anti-aging activity through dose-dependent inhibition of collagenase (IC50 58.7 µg/ml), elastase (IC50 82.5 µg/ml), hyaluronidase (IC50 191.4 µg/ml), and tyrosinase (IC50 158.6 µg/ml). Additionally, RcNps exhibited antibacterial activity against Staphylococcus epidermidis, Streptococcus pyogenes, and Pseudomonas aeruginosa, and suppressed biofilm formation.
- 02 Rose flower extract demonstrated peak anti-tyrosinase activity.

Formulation
Stability
Rosa Floribunda Flower Extract is soluble in both aqueous solutions and oil-based formulations, with solubility dependent on the specific extraction process. While optimal pH for this specific extract is not defined, other rose extracts show stability between pH 4.0-7.0.
Safety
Safety Profile
Rosa Floribunda Flower Extract is generally considered safe for cosmetic use. Although the CIR Expert Panel has not specifically assessed this species, related rose extracts (e.g., Rosa centifolia, Rosa damascena) are deemed safe when formulated to be non-sensitizing. Rare irritation may occur in individuals with very sensitive skin. Formulators should be aware that volatile components like citronellol and geraniol, common in rose extracts, are recognized fragrance allergens requiring labeling if exceeding 0.001% in leave-on products or 0.01% in rinse-off products in the EU.
