The discovery allows for the creation of sunscreen on the basis of forest fruit.
The study found the protective effect of strawberry extract against damage causing UVA radiation on skin cells, says lead researcher Dr. Maurizio Battin of the University Politecnica delle Marche in Italy.
It was found that UVA rays damage the DNA of cells and lead to premature aging. Their influence provoked the formation of wrinkles and even skin cancer development.
The other type, UVB rays cause burning of the skin and directly damage the DNA of skin cells. According to scientists, they are associated with most types of skin cancer.
Data from recent laboratory tests confirm that the extract of strawberries, particularly at a concentration of 0.5 mg / ml shows photo-protective effect in fibroblasts – connective tissue cells that are exposed to UV radiation. There is an increase in cell survival and vitality and reduce DNA damage.
According to researchers, the effectiveness of strawberries is due to the content of anthocyanins – the pigments that give the red color of the fruit. The compounds have anti-inflammatory, antioxidant and anticancer properties and are able to modulate enzymatic processes, explains Dr. Tulipani Kappa from the University of Barcelona.
