block it out

Expert Tip

Finding a good sunscreen is of the utmost importance. Replacements, such as makeup products with SPF are not enough to block powerful UVB rays. In fact, Dermatologist Leslie Baumann, M.D., says, “You need seven times the normal amount of foundation and 14 times the normal amount of powder to get the sun protection factor on the label.” Instead, try replacing toxic sunblock with SPFs designed for people who have sensitive skin or for children. These lotions use ingredients such as titanium dioxide or zinc oxide to replace hazardous chemicals previously mentioned.

Sunscreens with higher SPF ratings block slightly more UVB rays than their lower-SPF counterparts. For example, SPF 15 products block about 94 percent of UVB rays, while an SPF 30 product blocks 97 percent of UVB rays. No sunblock, however, o ers 100 percent protection. And although slathering your skin in extra sunscreen may seem like a keen idea, ingredients found in the SPF that you so readily apply may be doing more harm than good. Watch out for the following ingredients on the label of your SPFs.

OXYBENZONE Heat rash? Think again. This penetration enhancer undergoes a chemical reaction when exposed to UV rays. This reaction can cause an eczema-like allergic reaction that can spread beyond the exposed area and last long after you’re out of the sun. Experts also suspect that oxybenzone disrupts hormones, which can throw o your endocrine system.

OCTINOXATE. This chemical may be a culprit for premature aging, as it produces menacing free radicals that can damage skin and cells.

RETINYL PALMITATE. FDA studies have shown that retinyl palimitate may speed the development of malignant cells and skin tumors when applied to skin before sun exposure.

OCTOCRYLENE. When this chemical is exposed to UVB light, it absorbs the rays and produces oxygen radicals that can damage cells and cause mutations. It is readily absorbed by your skin and may accumulate within your body in measurable amounts. It can also be toxic to the environment.
