The Beauty Secrets of Coffee - Antioxidant potential
Antioxidants are substances that counteract the harmful activity of molecules known as free radicals. Several laboratory analysis confirm their effectiveness. Free radicals are formed naturally in the body, frequently due to stress or to some environment toxins.
They are very reactive and can cause serious disorders to cells. Experimental data indicate a causative role of radicals in aging processes including damages that may lead to neurodegenerative, cardiovascular or cancer diseases.
The coffee beverage is a very rich source of beneficial antioxidants such as polyphenols and melanoidins. Coffee polyphenolic antioxidants and caffeine have an important skin properties. These molecules showed proven efficacy against photoaging and photodamage. Oxygen radical absorbance capacity (ORAC) of coffee extract has substantially more capacity to scavenge free peroxyl radicals in comparison with other antioxidant-containing formulations and antioxidant compounds such as green tea, red wine, pomegranate extract, vitamins C and E.
On the other hand, caffeine shows a potent antioxidant activity. It helps to protect cells against the UV radiation and slows down the process of photoaging of the skin even when administered orally. It is also widely applied as an active compound within cosmetic formulations such as anti-cellulite, anti-aging, sunscreen and hair care ingredient thanks to its extraordinary properties for the skin.
According to recent studies, the amount of antioxidants is much higher in coffee than in other popular drinks such as wine, green tea or fruit juice. The graph shows the comparison between the anti-radicals activity of coffee with other common beverages.
