Tip of the month: You think you're safe from the sun?

Listen, it's all well and good to warn people about exposure to too much sun as well as the dangers of chemical laden commercially prepared sunscreens but for goodness sake, PRINT A WARNING when you're advising people to make their own sunscreen using powdered minerals. It is VERY unhealthy to inhale powdered zinc and any recipe containing that as an ingredient should include a cautionary statement. Wear a dust mask, mix this recipe in a well ventilated area (without a breeze to spread that dust around), and make sure it doesn't get everywhere. It's stable in a creamy base but must be handled with care before hand. Properly store any left overs.
And keep in mind that a homemade sunscreen doesn't have a number rating so you'll have to take care to avoid over exposure and reapply as needed.

The author of this article should be more careful not to over-exaggerate what is written in her sources and to misrepresent the scientific conclusions by suggesting a stronger and more alarming conclusion.

For example here it is claimed that "sunscreen contains toxic chemicals, like vitamin A, known to cause cancer".

Well that's not the same as what is stated in the referenced article:
"Research by the federal Food and Drug Administration and National Toxicology Program suggests that this chemical may heighten skin cancer risk when used on sun-exposed skin. Until definitive research is available, EWG recommends that prudent consumers avoid vitamin A-laden sunscreens."

I don't believe that "may heighten skin cancer risk" should be translated into "known to cause cancer" at all, especially since they also state that the research is not definitive. "Known" means a proven fact, but "may heighten risk" means it is unproven and has the possibility of turning out to be a false positive after further research, since the state of research is described as not being definite yet. This kind of ideological dishonesty diminishes the scientific credibility of this article.
