Sun Protection Factor or SPF is a measure of a sunscreen's ability to reduce the effects of sun exposure by absorbing or reflecting ultraviolet B (UVB) radiation. Products with high SPF ratings have the ability to protect skin from a larger percentage of the UVB rays in the environment than formulas with lower SPF ratings.
All of the sunscreens in this product assortment have a minimum SPF of 50, which indicates that they reduce skin's exposure to UVB by about 98 percent. Formulas that are labeled as "broad-spectrum" also keep the skin from absorbing some of the ultraviolet A (UVA) energy from the sun to provide more complete sun protection.
Formulas with High SPF Ratings
Anyone who wants to greatly reduce their exposure to UVB can choose to use a sunscreen with a high SPF rating; however, the products in this assortment are especially ideal for certain individuals. SPF requirements can vary based on skin type and medical history as well as geographic location, time of year and time of day.
Finding the Best Sunscreen
Sunscreens with high SPF levels come in a wide array of forms, including lotions, gels, creams, sprays and sticks. Some products are water-resistant sport formulas
that are ideal to wear when you're swimming or exercising. The product names and descriptions can be helpful when deciding which sunscreen will be right for you. You can always check with your doctor or pharmacist for recommendations as well.
