Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Ascophyllum nodosum, a brown seaweed, is increasingly used in skincare products due to its rich content of bioactive compounds, including polysaccharides (such as fucoidan and alginate), polyphenols, vitamins, and minerals. Several in vitro and limited in vivo studies suggest that extracts from A. nodosum may have antioxidant, anti-inflammatory, and moisturizing properties. These properties are thought to help protect skin from oxidative stress, support the skin barrier, and reduce signs of aging. For example, polysaccharides from the seaweed have been shown to retain moisture and promote collagen production in skin cells in laboratory settings. Some small-scale clinical studies and product-based trials suggest improvements in skin hydration and elasticity with topical application, though sample sizes are often limited and methodological quality varies.

Despite this, robust, high-quality human clinical trials are lacking, and most evidence comes from cell culture studies or animal models. The use of A. nodosum in skincare is relatively recent and is driven by the cosmetic industry’s trend toward marine-derived actives. While there is growing scientific interest and some promising preliminary results, the overall quality and quantity of evidence is still modest, supporting a rating of 2 out of 5. More rigorous and larger-scale clinical studies are needed to conclusively validate the efficacy of A. nodosum for general skin care.
