There has been a bit of controversy because of the Nanoparticle issue. They work by reflecting UVA and UVB rays away from the skin. The two main ingredients are Zinc Oxide and Titanium Dioxide, which in of themselves, are perfectly safe. Mineral Sunblock is used by most of the “natural” brands. If you are in and out of the water/sweating a lot (even if it says it’s water-resistant, you can’t be sure. Moreover the SPF doesn’t take into account:ģ. In a recent Consumer Reports study, there was a huge gap between the SPF claim and the actual SPF of quite a few companies. The other fishy thing about the supposed SPF of a sunscreen is that it’s not an exact science, and is often completely off, even in an SPF 30 sun screen. Remember anything higher than an SPF 50 on a label is just marketing, and dangerous because it gives people (especially kids), a false sense of security. You need to purchase a broad-spectrum sunscreen to make sure you are protected from both UVA and UVB rays. However, SPF only refers to UVB (the burning rays,) not UVA rays, which are the ones responsible for deep-down damage and accelerated aging. So, if you normally turn beet red after 10 minutes, the theory goes that if you slather yourself in SPF 30, you should be good for 5 hours. This means that you can stay in the sun 30 times longer without burning, than you would be able to were you not wearing sunscreen. The truth is that the highest protection you’re ever really going to get is about SPF 30 (conservatively speaking). The higher the SPF, the safer I’ll be, right? Not so. But, as usual, let me begin by separating truth from fiction:
SUNFORGETTABLE PERFECTLY CLEAR SKIN
Could a topic be more complicated than a simple sunscreen? Seriously – with skin cancer rates, and SPF’s on sun screens both on the rise, it seems odd that we haven’t managed to get a handle on the situation.
