Science
Mechanism of Action
This extract combats oxidative stress by neutralizing free radicals generated from environmental stressors like pollution and UV exposure, thereby mitigating cellular damage. It exerts anti-inflammatory action through the inhibition of key mediators such as IL1-alpha, IL6, and PGE2, which helps calm UVB-induced inflammation. Furthermore, it supports cellular renewal, strengthens the skin barrier via keratin production, and improves skin oxygenation, complexion uniformity, and radiance.

The Formula
Formulation
Stability
Polyphenolic compounds within whole rose flower extracts tend to exhibit good stability. However, the phenolic elements derived specifically from petals may be compromised or destroyed during alcoholic extraction processes. No specific optimal pH range for formulation stability was provided.
Conflicts
- High concentrations of alcohol during the extraction phase, which can degrade the extract's beneficial phenolic content.
- Presence of essential oil components like citronellol and geraniol (naturally occurring in rose) at concentrations exceeding 0.001% in leave-on products or 0.01% in rinse-off products, as these require specific allergen labeling under EU cosmetic regulations.
Safety
Safety Profile
The US FDA generally recognizes essential oils and natural extractives of several rose species, including Rosa alba, as safe (GRAS) for human consumption. The Cosmetic Ingredient Review (CIR) Expert Panel assessed related Rosa damascena-derived ingredients and concluded them safe for cosmetic use when formulated to be non-sensitizing. While the overall irritancy risk is considered low, products containing Rosa Alba Flower Extract may be contraindicated for pregnant or breastfeeding individuals if they also contain certain essential oils. Specific components, such as citronellol and geraniol, are identified fragrance allergens that necessitate labeling if their concentration exceeds regulatory thresholds.
