Science
Mechanism of Action
Rosa Centifolia Flower Extract functions as a potent antioxidant, neutralizing free radicals and mitigating oxidative stress to support skin vitality and combat signs of aging. Its anti-inflammatory capabilities soothe redness and irritation, while its humectant nature draws moisture into the skin, aiding in hydration and barrier replenishment. Specific forms, like floral water, also offer astringent effects, refining pore appearance and texture, and it possesses calming and potentially antimicrobial actions beneficial for diverse skin concerns, including acne.

Safety
Safety Profile
The CIR Expert Panel concludes that Rosa centifolia-derived ingredients, including the flower extract, are safe in cosmetics when formulated to be non-sensitizing. The main volatile constituents, citronellol and geraniol, are identified as potential sensitizers, requiring formulators to avoid concentrations that may induce adverse reactions. Under EC Cosmetics Regulation, these components must be listed on labels if their concentration exceeds 0.001% in leave-on products or 0.01% in rinse-off products. While undiluted Rosa centifolia flower oil was classified as a moderate skin irritant in rabbits, a 0.8% extract in a human patch test showed no irritation. Patch testing is advisable for sensitive individuals to confirm compatibility.
