Now that summer is in full swing, even the Pacific Northwest is sunny and bright which causes many people to turn to sunscreens so they can enjoy their favorite summer activities, while preventing overexposure to the sun. Skin cancer is the most common form of cancer in the United States with more than 3.5 million cases annually, so it should be a big concern for all; however in an attempt to minimize cancer risk many are causing additional damage to their bodies through the use of chemical laden products that can have allergic, carcinogenic and endocrine disrupting side effects.
Among the many ingredients that are often used in topical sunscreen, some of the most important to be aware of include:
Retinyl palmitate - A derivative of vitamin A which can serve as a potent anti-oxidant, this compound has been shown to break down when exposed to UV light and produce free radicals that can cause damage to DNA in mouse and rat studies. There is some controversy regarding whether or not these changes may occur in humans or if the free radicals produced are simply quenched by the antioxidant milieu in human skin. Topical retinoids are frequently prescribed for a variety of skin conditions with no published data to suggest that they increase skin cancer risk; however it is currently restricted from being used in cosmetics in Canada and Japan.
Oxybenzone - This compound is an aromatic ketone and one of a greater category of organic compounds called benzophenones that are included in sunscreens as broad-spectrum UV blockers. Oxybenzone is present in close to half of all sunsreens and problems include a high photoallergic potential (meaning that an allergen is produced with UV exposure causing contact dermatitis), but our primary interest in this chemical is the estrogenic effect it has on the endocrine system.
Nanoparticles - Mineral based UV filters such as titamium dioxide and zinc oxide have long been used in sunscreen products and have a low photoallergic reaction rate as well as relative stability in the sun. Issues with these products have largely been cosmetic, as they tend to produce an opaque or white appearance on skin. Newer formulations are using nanosized particles of these minerals to minimize the cosmetic impact and while that has raised question of systemic absorption and toxicity, analysis has been unable to demonstrate toxicity so these may be one of the best bets when it comes to UV blockers.
Keep in mind that large amounts of UV exposure do increase the risk of certain skin cancers, especially basal cell and squamous cell carcinomas and therefore protection from the sun is very important. We recommend you do some research and choose sunscreens with the fewest amounts of endocrine disrupting ingredients along with a combination of timing your outdoor activities when the sun is not at its peak and covering exposed skin with light weight cotton materials or hats.

I'm short of words to express the goodness of God in my life. I was diagnosed of herpes simplex virus 4 years ago. Which was the worst time in my life. I became worried,distress,felt so rejected,dirty and pity by so many,friends,family and most all my lovely girlfriends. I started keeping in touch with many hospitals,tried many solutions,and consulted many medical practitioners to get ride of my HSV virus,none of the ativiral treatment could cure me .I started trying fruits and herbs, and with time became very interested in herbs for solutions,to get ride of my HSV. I thought my life was gonna end there, i became worried and couldn't sleep at night. On faithful Sunday morning,when the appointed time came for my breakthrough, my lovely girlfriend, crystal who visited me home came up with a good news with her HSV test result negative. I was shocked,but so happy to have seen that. I wouldn't believe if I haven't seen the result and that would have being my worst mistake in life. She told me it was the work of an herbalist in Africa,Dr.Elabe. who prepared the HSV cured and sent it to her through the DHL. I became very interest and went online to search for natural ways for my cure then I saw a testimony of a lady comments on how she was cured from cancer by the same herbalist, then,I quickly email him@
