3. Higher SPF means less risk for skin cancer.

Speaking of SPF, many people don’t know how it works. In order to minimize your skin cancer risks, you should at least learn how to choose the right SPF. The higher the Sun Protection Factor (SPF) value, the better sun protection it can offer, and the greater your chances of avoiding skin cancer.

Sunscreen with SPF 15 is generally a good choice for everyone. Based on studies, it’s enough to cut your risk of developing skin cancer by half. But if you have a light-colored skin tone, a family history of skin cancer, or any medical condition that makes your skin more sensitive to sunlight, you should go for products with SPF 30 or higher.

Usually, a higher SPF rating means better sun protection. With proper application, SPF 15 can give you 93% protection from cancer-causing UVB rays, SPF 30 can give you 95-97% protection, and SPF 100 provides up to 98% protection. SPF also determines how long a sunscreen’s protection lasts before you get sunburned. As a rule of thumb, the SPF value should be multiplied by 15 – the result will show how many minutes before your skin gets toasted. That means SPF 15 can shield you from the sun for 150 minutes, SPF 30 for 450 minutes, and SPF 100 for 1,500 minutes.

Regardless of the SPF, dermatologists recommend reapplying sunscreen every 2 hours and to wait for at least 30 minutes after application before exposing your skin to sunlight.
