Your Skin & the Sun

the 411 on sun exposurer

Even though summer is coming to an end, we still need to be smart about the sun. Some of you will take sunny vacations in the winter so be prepared. Some sun is great for assisting our bodies in producing vitamin D. During the summer months or in more tropical climates, about 20 minutes of unprotected sun exposure, preferably in non-peak hours (10 a.m to 3 p.m.), is all we need to give our bodies a boost of this essential vitamin that has been long overlooked. But any more than that and we need to protect our skin from the sun's harsh rays to prevent premature aging:  sagging skin, age spots and those dreaded wrinkles!

Staying indoors, donning a wide-brimmed hat and wearing long sleeves are great options, but when we want to enjoy the great outdoors we need sunscreen. Seems easy enough when there are hundreds of products to choose from on every store shelf. But as you have probably heard there is a lot of talk about the safety of sunscreen. Unfortunately, we can't rely on the FDA to protect us from the scads of sun "protections" sold. Below is a list of common ingredients found in popular sunscreens today and the problems associated with them. Don't just take our word for it, Google the ingredients for yourself. And most are full of nasty parabens to boot!

  • Titanium dioxidecauses DNA damage (the cells genetic material) due to superoxide radicals, active oxygen radicals and hydroxyl radicals when exposed to light (1) (2) (3)
  • Octyl-methoxycinnamateproduces free radicals (singlet molecular oxygen) known to be toxic to cells (4)
  • PABAproduces free radicals in the presence of light (4)
  • Oxybenzoneis rapidly oxidized in the presence of light and inactivates important antioxidant systems in the skin (the skin’s natural protection system) (5)
  • Cinoxatecauses DNA damage (sister chromatid exchanges) (6)
  • Padimate-Oproduces free radicals in presence of light (singlet molecular oxygen) and substantially increase indirect damage (strand breaks in DNA) when in contact with cells (1) (7)
  • Dibenzoylmethane and Parsol 1789produces free radicals responsible for direct DNA damage (strand breaks) (8)
  • Methyl sinapate causes DNA damage (chromosome aberrations and sister chromatid exchanges) (9)
  • Phenylbenzimidazole sulphonic acid and 2-phenylbenzimidazoleacts as photosensitisers of DNA damage when exposed to sunlight or UV- B radiation (10)
This is why we are so excited about our newest find, Soleo Organics! With Soleo's SPF 30+ Water Resistant sunscreen, it's safe to go back in the water and the sun! Although the hat is a fashion must, ditch the sleeves and grab the Soleo.
