polyphenol-rich plant extracts + hyaluronic acid + Cetraria islandica + vitamin B3

This is a **combination product** containing four main active components: polyphenol-rich plant extracts, hyaluronic acid, Cetraria islandica (Iceland moss) extract, and vitamin B3 (nicotinamide). - **Polyphenol-rich plant extracts** are widely recognized for their antioxidant and anti-inflammatory activity, primarily attributed to plant polyphenols that scavenge free radicals and modulate oxidative stress. - **Hyaluronic acid** is a naturally occurring glycosaminoglycan used for its hydrating, lubricating, and wound-healing properties, especially in skin and mucous membrane formulations. - **Cetraria islandica (Iceland moss)** contains polysaccharides and lichen acids (fumarprotocetraric acid, protolichesterinic acid) and is traditionally used for its **antimicrobial, anti-inflammatory, demulcent, and immunomodulatory effects**. Its main active polysaccharide, lichenan, has demonstrated stimulation of dendritic cell maturation and secretion of IL-10, which points to an anti-inflammatory effect[1][3][4][5]. - **Vitamin B3 (nicotinamide/niacinamide)** is involved in cellular metabolism, supports skin health, and has been shown to exert anti-inflammatory, antioxidant, and immunomodulatory activities[7]. This combination is typically formulated for use as a **dietary supplement or over-the-counter product** for general wellness, respiratory or digestive support, or dermatologic/skin uses.
