Understanding Sunscreen Labels Helps Achieve Maximum Protection
July 24 , 2007 by EditorDermatologist Tips for Purchasing Sunscreen
Wayne, PA - Sixty-two percent of Americans surveyed in a new survey* by PreSun Sunscreen products indicate they do not purchase a new sunscreen at the start of every spring/summer season (instead, using what was left from last summer). "Extreme temperatures, including being in a suitcase or hot car, can shorten sunscreen's shelf life, so it's safest to buy a new bottle at least every summer season," explains Florida-based dermatologist Craig Eichler, M.D.
Here, Dr. Eichler offers his tips for purchasing sunscreen:
- Look for Broad-Spectrum Ingredients: Not all sunscreen ingredients are created equal- some provide minimal protection against ultraviolet A (UVA) radiation, which can cause skin cancer and wrinkles. UVA is not considered in the sun-protection factor (SPF), which refers to protection against UVB radiation, a different wavelength that can also cause skin cancer, plus sunburn. Look for products with an effective broad-spectrum sun-blocking ingredient, such as Parsol 1789, which protects against both UVA and UBV rays.
- The ABCs of SPF: Look for sunscreens with a minimum of SPF 15. A sunscreen's SPF represents the level of protection the product provides: SPF 15 blocks about 93% of UVB rays and SPF 30 blocks about 98%, explains Dr. Eichler. "For most people, an SPF 15 will be adequate for short and less intense sun exposures, but SPF 30 is recommended if you are going to be exposed to the sun for a long period of time or intense sunshine."
- Waterproof vs. Water-resistant: Products labeled "waterproof" may provide protection for at least 80 minutes even when swimming or sweating. "Water resistant" products may provide protection for only 40 minutes.
- No Excuses: Some people don't use sunscreen because they don't like the way it feels on their skin, so look for an application that is comfortable for you. "If cream sunscreens feel too heavy, try a gel or spray, such as PreSun Gel, which has a light feel, or the new PreSun Spray, which is quick to apply and very light, making it great for kids and active adults," says Dr. Eichler. "In addition to protecting skin from UVB rays, PreSun Sunscreen products are formulated to protect skin from UVA rays with Parsol 1789, which is widely regarded as one of the most effective UVA blockers," he adds.
