As the summer approaches and everyone will be pulling layers of clothes off their backs, we are all concerned with getting beautiful tanned skin. Women in particular are ready to throw their favorite summer dresses on and bare their skin and show off beautiful sun glazed legs.As the weather warms up everyone is running to the beach or pool and ready to intake as much sun as possible. Moderate sun exposure is healthy and necessary but we should also keep in mind sun damage ans skin cancer that comes along with sun exposure.
Herbs have been used in medicines and cosmetics from centuries. Their potential to treat different skin diseases, to adorn and improve the skin appearance is well-known. As ultraviolet (UV) radiation can cause sunburns, wrinkles, lower immunity against infections, premature aging, and cancer, there is permanent need for protection from UV radiation and prevention from their side effects. Herbs and herbal preparations have a high potential due to their antioxidant activity, primarily. Antioxidants such as vitamins (vitamin C, vitamin E), flavonoids, and phenolic acids play the main role in fighting against free radical species.
Have you ever thought that natural compounds in fruits particularly grapes could help protect our skin against sun damage?
In a quest to find effective topical photo protective agents, plant-derived products have been researched for their antioxidant activity, so the use of natural antioxidants in commercial skin care products is increasing. Today, we look at the chemical composition of herbal remedies to ascertain
The skin’s natural sun blockers are proteins (the peptide bonds), absorbing lipids, and nucleotides. The high concentration of plant peptides protects the peptide bonds of the skin proteins.
Natural chemicals contained in grapes can help your skin defend itself against sun damage.
Research at the University of Barcelona shows that phyto nutrients in grapes can slow down the formation of destructive reactive oxygen species (ROS) that form in skin cells. ROS may be linked to sun damage, skin cancer and cell death.
The Spanish scientists believe that these flavonoids can be used in skin-care products that keep the sun’s ultraviolet radiation from negatively affecting skin cells. If you eat grapes, these compounds can also be taken up by the skin and promote better skin health.
Rutin is found in trees in small and medium-sized regions of the Brazilian cerrado and caatinga. The substance is also present in onions, grapes and in red wine.
Rutin is a flavonoid, traditionally used as an antioxidant and vasoprotetor, which increases venous tone and reduces the capillary hipermeabilidade and edema formation, says the professor. It also acts to prevent the damage caused by ultraviolet radiation.
The results of this research indicate that the flavonoids have a tendency not to penetrate the stratum corneum of the epidermis, remaining on the skin surface. This led the researchers to use as an adjunct to routine systems sunscreens, because of its chemical structure similar to the filters on the market, and tends not to be absorbed through skin.
Over the past few years, grapes have taken center stage in the world of superfoods, thanks to an anti aging compound in grape skins known as resveratrol. But it turns out that the lowly grape has even more to recommend it—health benefits found in the seeds. In fact, the tiny seeds of this juicy fruit harbor compounds that can make us look and feel younger and more vibrant both inside and out thanks to their potent antioxidant power. These miniature marvels are so powerful that they outperform vitamins C and E and beta-carotene, making grape seed extract a highly effective warrior against the
free radical damage that can injure our DNA and age us prematurely.
What It Is
Grape seed extract’s antioxidant power is 50 times greater than that of vitamin E and 20 times more potent than vitamin C. It also boasts anti-inflammatory and antimutagenic properties, as well as the ability to protect against the harmful effects of radiation in animal studies.
Yet these abilities aren’t grape seeds’ main claim to fame. Grape seeds contain substances called proanthocyanidins, commonly referred to as oligomeric proanthocyanidins. These water-soluble flavonoids help to strengthen and protect our cell membranes from the oxidative damage caused by free radicals. Without this protection, our skin begins to prematurely show the signs of aging from overexposure to the sun’s harmful rays. According to researchers at Creighton University in Omaha, Neb., grape seed extract applied topically boosted the skin’s natural SPF (sun protection factor) in a group of human volunteers.
What It Does
Studies show that grape seed extract, especially when combined with other antioxidant-rich compounds (such as white tea and tomato extract), promotes youthful skin by enhancing the health of skin cells as it protects elasticity and flexibility. Specifically, these skin-friendly seeds increase the synthesis of collagen and elastin—the two pillars underlying structures of youthful skin. Grape seed is so effective that when postmenopausal women took a supplement containing the extract for six months, they experienced significant improvement in the crow’s feet, wrinkles around the mouth, age spots, sagging, and even the dark circles under their eyes compared to women taking a placebo.
Grape seeds’ benefits go far beyond skin health. In Europe, extracts of the seeds are used for a variety of circulatory problems, including varicose and spider veins. Grape seed extract also improves the flexibility of the arteries that take blood from the heart, as well as boosting overall circulation.
