Science

Mechanism of Action

Rosa Centifolia Extract contributes to skin vitality through multiple pathways. It actively stimulates the synthesis of collagen and elastin, foundational proteins crucial for maintaining skin firmness and elasticity. Rich in bioactive compounds such as flavonoids and anthocyanins, it functions as a potent antioxidant, safeguarding skin cells from oxidative damage induced by free radicals. The extract also possesses significant moisturizing capabilities, aiding in maintaining skin's suppleness, alongside soothing and anti-inflammatory actions that help mitigate irritation and support skin recovery. Additionally, its astringent properties assist in cleansing and purifying, while Vitamin C content promotes healthy cellular turnover.

Max tested
0.096%
Sensitization risk Moderate

The CIR Expert Panel deemed 9 Rosa Centifolia-derived ingredients safe in cosmetics when formulated to be non-sensitizing. The highest reported maximum use concentration in a 2021 survey for a derivative, Rosa Centifolia Flower Water, was 0.096%. Formulators are advised to carefully manage levels of naturally occurring fragrance allergens, citronellol and geraniol, which the SCCS mandates for labeling if they exceed 0.001% in leave-on or 0.01% in rinse-off products. While the extract is generally considered safe, sensitive individuals may experience irritation; patch testing is advisable. The FDA recognizes essential oils, oleoresins, and natural extractives of rose absolute (including Rosa centifolia L.) as Generally Recognized As Safe (GRAS) for food and drug use.
