Mechanism of Action
The precise mechanism of action for Defatted Hydrangea Macrophylla Flower is primarily inferred from research conducted on Hydrangea Macrophylla Leaf Extract, a related botanical component. This leaf extract is believed to act as a protective skin 'cloak,' enhancing the skin's natural resistance against external environmental factors. It reportedly promotes cellular regeneration and, through its plant polysaccharides, helps establish an imperceptible moisture barrier to maintain skin hydration and softness. Additionally, its antioxidant properties are theorized to combat free radical damage, potentially diminishing visible signs of skin aging. The ingredient may also contribute to reducing skin irritation and improving overall tone and texture. It is crucial to acknowledge that these mechanisms are largely extrapolated from the leaf extract and may not entirely translate to the defatted flower extract.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded 'insufficient data to determine safety for use in cosmetics,' with no reported usage found in the FDA database for this specific ingredient. A significant concern arises from the fact that all parts of the raw Hydrangea macrophylla plant are considered potentially toxic if ingested and can induce dermatitis, rash, or irritation upon direct skin contact. This necessitates rigorous safety testing for the defatted flower extract prior to cosmetic formulation.

Verdict
Due to insufficient safety data from regulatory bodies and the primary mechanism of action being extrapolated from a related plant extract, further direct research on Defatted Hydrangea Macrophylla Flower is essential before widespread and confident cosmetic recommendation, especially given the raw plant's documented irritant potential.
