ROSA LAEVIGATA FRUIT EXTRACT.

This extract enhances skin health through several interconnected mechanisms. It deeply hydrates by improving the skin's moisture retention capacity, strengthening the barrier function, and thus reducing transepidermal water loss. Its anti-inflammatory properties stem from compounds that inhibit the production of pro-inflammatory mediators, with in vitro evidence showing inhibition of NF-κB/MAPK signaling pathways via AMPK activation. Acting as a potent antioxidant, it neutralizes free radicals, thereby mitigating oxidative stress that contributes to premature aging. Phytochemicals such as flavonoids, triterpenoids, and polysaccharides are key contributors to its antioxidant, anti-inflammatory, and immunomodulatory effects, with polysaccharides specifically shown to decrease malondialdehyde levels and increase antioxidant enzyme activities in cellular models.
