Science
Mechanism of Action
This extract operates through a multifaceted approach, harnessing its abundant antioxidants, including flavonoids and vitamins, to shield the skin from environmental stressors and mitigate inflammation by attenuating MAPK signaling pathways and reducing sUV-induced COX-2 expression. Its inherent antibacterial and anti-inflammatory attributes actively soothe redness and irritation, while its hydrating capacity helps restore optimal moisture. Furthermore, it contributes to skin brightening by inhibiting melanin generation and offers anti-wrinkle and firming effects by inhibiting elastase activity, promoting skin regeneration and maintaining a delicate pH balance.

Key findings
- 01 In vitro studies demonstrate that Rosa Damascena Flower Water Extract (RDE) at concentrations between 0.05% and 0.5% significantly inhibits melanin production, showcasing skin whitening effects. The 0.5% concentration proved particularly effective in both whitening and elastase inhibition, contributing to anti-wrinkle benefits.
- 02 The extract exhibits robust antioxidant activity, with one form (RDF) achieving over 90% DPPH free radical scavenging, notably superior to RDE, indicating strong protective capabilities.
- 03 Research, including a 2020 human subject study, supports rose water's anti-inflammatory effects on the skin, particularly following sun exposure, by reducing inflammatory signaling pathways. It also consistently showed antioxidant and anti-wrinkle formation activity, likely linked to its inflammation-inhibiting properties.

The Formula
Formulation
Stability
As a hydrosol, Rosa Damascena Flower Water Extract is more susceptible to degradation compared to essential oils. Optimal freshness and prevention of contamination require proper preservation and, ideally, refrigeration. For seamless integration and stability, it is recommended to add the extract to formulations when temperatures are maintained below 50°C. It demonstrates broad compatibility across various personal care ingredients.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Rosa damascena-derived ingredients are safe for use in cosmetics, provided they are formulated to be non-sensitizing. While generally well-tolerated, rare allergic reactions may occur in individuals with specific sensitivities to rose plant compounds, hence patch testing is advisable. Natural fragrant components such as citronellol, geraniol, and linalool may be present and require specific labeling if their concentrations exceed regulatory limits in certain regions (e.g., 0.001% for leave-on products).
