Here is a general rule to live by: "If it's not safe to eat, it's not safe to apply to skin," and sunscreens are definitely not safe to eat. Loaded with toxic chemicals, I wonder if the majority of sunscreens are actually the cause, not the solution, to increasing cases of skin cancer year after year. Oxybenzone is one of the most common ingredients in traditional sunscreens, yet it is a known carcinogen. Spray-on sunscreens are also a big concern, since you are very likely inhaling small particles that may or may not be safe for you.
A seal from the Skin Cancer Foundation does not mean that a sunscreen is safe either, as the foundation will place its seal on any sunscreen that has an SPF rating higher than 15, or on the product of any company that donates $10,000.
So what's the solution? For starters, stop buying the myth that the sun is the enemy. Vitamin D is essential to a healthy body, and many of us our not getting enough because we see the sun as our enemy. Purchase sunscreen with zinc instead of synthetic chemicals which will block rays naturally. Badger Brand has a great line of natural products that fit the bill - organic, bio-degradable, broad spectrum, water resistant, and safe for your whole family.
