What is SPF?
A higher SPF than 50 doesn't really necessarily mean better protection from the sun, because they require higher concentrations of sun-filtering chemicals than low-SPF sunscreens, plus it's more expensive and potentially more toxic.
What's toxic about shelf-bought sunscreens?
Sunscreen’s active ingredient comes in the form of chemical and mineral filters. It’s the chemical sunscreens that are causing need for concern.
According to the EWG,
[chemical sunscreens] include a combination of three to six of these active ingredients: oxybenzone, avobenzone, octisalate, octocrylene, homosalate and octinoxate. The most problematic of the sunscreen chemicals used in the U.S. is oxybenzone, found in 80 percent of chemical sunscreens. EWG recommends that consumers avoid oxybenzone because it can penetrate the skin, cause allergic skin reactions and may disrupt hormones.
Most of us trust what's on the market, we think "they" have our best interest, but sadly they don't! If they did, they would NOT be allowing these toxic chemicals to be put in the sunscreens our children are using!
