The Beauty Secrets of Coffee: Anti-ageing properties
Today, science devotes much space to the causes of skin ageing as this may help predict certain diseases. At the same time it helps to find out how to counteract the signs of ageing and appear young for a long time.
The skin is a sensory and protective organ responsible for the maintenance of temperature, electrolyte and fluid balance. Over time, it is exposed to many external and internal factors that cause its loss of functions resulting in the appearance of visible signs of ageing. Studies show that UV radiation is the main cause of premature skin deterioration in the parts of body that are often exposed to the sun during the day as face and neck. The cause is oxidative stress, which is the formation of free radicals that skin is not sufficiently able to counteract alone. However, the good news comes from clinical studies showing that the topical use of antioxidants could be a viable option for skin protection against oxidative stress.
Many plant species are very rich in polyphenols-natural antioxidants, suitable for use in cosmetic formulations.
Coffee extract contains many active polyphenolic compounds such as condensed proanthocyanidins, chlorogenic, quinic, and ferulic acids with proven efficacy against photoaging and photodamage. Oxygen radical absorbance capacity (ORAC) of coffee extract (water-soluble and lipid-soluble components) has substantially more capacity to scavenge free peroxyl radicals in comparison with other antioxidant-containing formulations and antioxidant compounds such as green tea, pomegranate extract, vitamins C and E.
The subsequent study of 40 female participants showed clearly that a topical mixture containing Coffea arabica after 12 weeks significantly improves the appearance of wrinkles, firmness, redness, and texture of the face skin. It also had a positive effect on hyperpigmentation and no adverse events were observed.
