Orange is one of the foods with high content of vitamin C. Taking vitamin C or extend through cosmetic products improves wound healing and helps to counteract the signs of aging caused by external agents such as pollution, ultraviolet rays or snuff. This is confirmed by a new study published in ‘Free Radical Biology and Medicine.
“Our study shows a mechanism by which vitamin C helps maintain healthy skin. First, it improves healing of wounds and also because it protects DNA from oxidation by free radicals (oxygen molecules responsible the destruction of healthy cells and premature aging of the skin), “said Marcus Cooke, lead author of the article.Scientists from the University of Leicester (UK) and Institute of Molecular and Cellular Portugal have analyzed the effects of a derivative of vitamin C (ascorbic acid 2-phosphate) in dermal fibroblasts, a type of cell synthesizing collagen to the healing process. And the result was conclusive. The authors found that vitamin C increased the proliferation of fibroblasts and, consequently, could improve healing problematic.
“It’s new way of using it can improve healing complex for one reason or another,” explains Aurora Guerra, section chief of dermatology at the Hospital of University 12 October.
“It stimulates the division of fibroblasts and promotes their migration into the wound area. In addition, it also enhances their capacity to repair DNA damage produced, for example, solar radiation,” they said those responsible for this work . “Not only prevents and treats these types of damages, it also helps against skin cancer,” they add.
Although numerous studies have shown their anticancer effect and its role in the immune system and skin, “his properties are still under debate in the scientific community.” However, studies like this, say the authors, “have great significance in the cosmetics industry for it counteracts premature aging.
In fact, as Dr. Guerra says, “years ago that vitamin C is an essential element in cosmetics. It is an important anti-free and also has whitening action in the liver spots.”
According to pharmacodynamic studies, adds dermatologist, “Vitamin C applied topically (in these products, often recommended concentrations between 2% and 5%) achieves levels 30 times higher in the skin to those achieved with oral administration (dose Recommended: 120 mg.). But both routes are preferable to the only systematic “.
