SPF 70 indicates that a sunscreen provides a high level of protection against UVB rays, which are primarily responsible for sunburn and can contribute to skin cancer. The SPF number measures the amount of time you can stay in the sun without getting burned compared to not wearing sunscreen. For example, if you typically burn after 10 minutes of sun exposure, SPF 70 theoretically allows you to stay in the sun for about 700 minutes without burning, although this is a simplified calculation and actual protection can vary based on factors like skin type, water exposure, and reapplication. It's important to apply sunscreen properly and reapply regularly for effective protection.
How long is the vacation? You are still apt to burn with fair skin if you are using SPF 15 for 7-10 days longer.

To find the mean of the numbers 70, 70, 81, 85, and 74, add them together: 70 + 70 + 81 + 85 + 74 = 380. Then, divide the total by the number of values, which is 5: 380 ÷ 5 = 76. Therefore, the mean is 76.

SPF 70 offers a higher level of protection against UVB rays compared to SPF 30, blocking approximately 98.6% of UVB rays versus 96.7%. However, the difference in protection is relatively small, and both SPF levels are effective for sensitive skin. It's essential to choose a sunscreen that is formulated for sensitive skin, regardless of the SPF, to minimize the risk of irritation. Additionally, proper application and reapplication are key factors in achieving effective sun protection.

Sun Protection Factor

"The sun protection factor of a sunscreen is a laboratory measure of the effectiveness of sunscreen --- the higher the SPF, the more protection a sunscreen offers against UV-B (the ultraviolet radiation that causes sunburn)."
