Dermatologists issue warnings against DIY sunscreen

With DIY beauty treatments being all the rage for frugal-loving fashionistas, it’s no surprise that this summer has seen a number of homemade potions being concocted in preparation for the hot weather – but be wary, as these alternative remedies don’t offer the same amount of protection compared to their company-manufactured counterparts. New York-based Dermatologist, Whitney Bowe, explained that developing and applying your own sunscreen is “effectively putting your skin at risk for melanoma”. “Sunscreen companies invest millions of dollars formulating and testing sunscreens to ensure they are stable and effective,” she explains. “Tests are conducted in the lab and on humans to ensure they provide broad-spectrum protection and that the ingredients remain stable and active when mixed together and exposed to heat and sun.” Popular ingredients found in these homemade sunscreens include oils such as almond, carrot seed, coconut and rosehip – components renowned for contributing to sunburns. Yet even when armed with the correct elements, there’s still a strong chance that you could mix them wrong and end up with a completely ineffective sunscreen. However, many beauty bloggers have raised concerns regarding store-bought products – highlighting that many of these sunscreens contain dangerous chemicals that can impact upon your hormones. Known as ‘endocrine disruptors’, these types of chemical sunscreens can alter the normal hormonal functioning; commonly affecting oestrogen, progesterone, testosterone and thyroid. So is there a happy balance? Apparently chemical-free sunscreens are the way forward. Assistant Clinical Professor of Dermatology at Columbia University, Dr Sherry Shieh, says: “The chemical-free sunscreens these days are excellent. They’re fragrance free and non-toxic.” What are your thoughts on DIY sunscreen? Let us know on Twitter.
