Science
Mechanism of Action
The benefits of Rosa Rugosa Bud Powder are attributed to its rich content of phytochemicals, including polyphenols (such as ellagic acid and gallic acid), flavonoids (like quercetin and kaempferol), and Vitamin C, which provide robust antioxidant defense by neutralizing free radicals. It also exhibits anti-inflammatory properties, aiding in the reduction of redness and swelling. Tannins present in the powder contribute astringent effects, which can help tone the skin. As a skin conditioning agent, studies indicate that Rosa rugosa extracts can induce keratinocyte differentiation, thereby enhancing skin barrier function through increased expression of key proteins like FLG, IVL, LOR, and CLDN1. Furthermore, specific phenolic compounds from the flower buds, such as rosarugosides A and D, have demonstrated anti-aging efficacy by suppressing intracellular Reactive Oxygen Species (ROS) production and decreasing MMP-1 secretion, alongside regulating procollagen type I α1 expression. The aromatic oils inherent in roses also provide a soothing effect to the skin.

Key findings
- 01 Rosarugoside D, a phenolic compound isolated from Rosa rugosa flower buds, significantly reduced intracellular Reactive Oxygen Species (ROS) production in TNF-α-induced human dermal fibroblasts (NHDFs) by 1.77-fold at a concentration of 0.03 µM, without cytotoxicity below 100 µM.
- 02 Rosarugoside A, another phenolic compound from Rosa rugosa flower buds, dose-dependependently decreased intracellular ROS production and significantly reduced MMP-1 secretion across concentrations of 1-100 µM in TNF-α-induced NHDFs.
- 03 A fermented Rosa rugosa 'Mohong' methanol extract demonstrated strong antioxidant properties with 92.27% ABTS radical-scavenging activity at 0.25 mg/mL.
