To protect your skin and reduce your risk of developing skin cancer, wear sunscreen every day. Many studies show that people do wear sunscreen. However, those same studies show that they're doing it wrong. You are best protected by broad-spectrum sunscreen with an SPF of at least 30. Higher SPF products filter out only slightly more sunlight so it isn't necessary to spend more money for higher SPF. What is essential is to apply a liberal amount of product to your skin. Experts recommend using one ounce of sunscreen for the body and one-third to one-half a teaspoon for the face and neck. Most people do not apply nearly that much. Then, if you're outdoors for more than a few hours, you must reapply your sunscreen periodically to maintain adequate protection. If you swim or sweat, your sunscreen is diluted and needs to be reapplied.
In addition to using sunscreen properly, you can protect your skin by reducing sun exposure during the peak hours of the day. Mid-day sun is bright and strong, so avoid it when possible. It can also be helpful to wear lightweight, long-sleeved shirts and pants when spending time outdoors. Keep in mind, as well, that your skin is absorbing sunlight even when you're in the car, so these tips for protection apply.
