Urolithin A description

Urolithin A is an antioxidant-rich natural compound produced when microbes inside the gut break down foods rich in ellagic acid, such as pomegranates, nuts and many types of berries. Ellagic acid is a polyphenol antioxidant. Its metabolite, urolithin A, also has antioxidant benefits, backed by studies showing it has potent free radical-scavenging abilities. Even more promising is research demonstrating that it can enhance skin longevity by preventing cell senescence. Cell senescence is one of the key biomarkers of aging. It’s a process where cells stop dividing and start sending inflammatory messages to nearby, healthy cells. Premature cell senescence increases skin’s biological age, resulting in the well-known signs of aging including wrinkles, discolorations and skin losing its ability to repair itself. Studies demonstrate urolithin A can mitigate the effects of senescence, including that caused by UVA radiation, which is a leading cause of skin aging and a contributor to every type of skin cancer. Additional research indicates that urolithin A may work by increasing removal of damaged mitochondria (mitophagy) and improving mitochondrial health. This leads to re-energizing the cells to reducing the breakdown of collagen and prolonging skin health. More research is needed, but urolithin A shows a lot of potential in becoming an anti-aging ingredient to watch. Urolithin-A may be plant-derived or synthetic. The research-supported use level of this ingredient in cosmetics is 1%.

Évaluation des ingrédients

Excellent

Ingrédient dont l’efficacité est prouvée et basée sur des études cliniques indépendantes. Un actif exceptionnel pour la plupart des types de peau ou problématiques cutanées.

Bon

Ingrédient nécessaire pour améliorer la texture, la stabilité ou la pénétration de la formule.

Moyen

Généralement non irritant, mais peut présenter des problèmes esthétiques, de stabilité ou autres qui limitent son utilité.

Mauvais

Un risque d'irritation est possible. Ce risque augmente lorsqu'il est associé à d'autres ingrédients problématiques.

Très mauvais

Peut provoquer irritations, inflammations, sécheresse, etc. Peut présenter un certain intérêt, mais s'avère globalement plus nocif que bénéfique.
