Definition
SPF measures protection from UVB, which causes sunburn and skin damage.
Expanded Explanation
When choosing a sunscreen product, it is crucial to consider the SPF rating. SPF is an acronym for Sun Protection Factor, which measures sunscreen’s protection against UVB rays. Excessive exposure to UVB rays can result in sunburns and heighten the likelihood of developing skin cancer.
However, SPF doesn’t measure UVA ray protection, which can cause skin aging and cancer.
SPF Ratings
A sun protection factor rating range from low (SPF 2) to high (SPF 100+), with higher numbers offering more excellent UVB protection:
- SPF 15: Blocks approximately 93% of UVB rays
- SPF 30: Blocks about 97% of UVB rays
- SPF 50: Blocks about 98% of UVB rays
Choosing the Right SPF
To select the proper SPF, consider the following factors:
- Skin type: Fair-skinned individuals may require a higher SPF for adequate protection.
- Sun exposure: Prolonged exposure to intense sunlight may necessitate a higher sun protection factor rating.
- Broad-spectrum protection: Opt for broad-spectrum sunscreen, which protects against UVA and UVB rays.
Examples
Example 1: To avoid sunburn at the beach, apply water-resistant sunscreen with SPF 30+ and broad-spectrum protection. This preventative measure will protect your skin from damaging UV rays so you can enjoy the beach without worry.
Additionally, it’s important to reapply sunscreen every two hours, especially after swimming or sweating.
Example 2: Protect your fair skin from further damage caused by the sun. Use a daily facial moisturizer with SPF 50 if you’ve had past sunburns. This will help protect your skin from the sun’s harmful rays to lower your risk of skin cancer.
Using a moisturizer can help keep your skin hydrated and soft while protecting against premature aging. So, apply a moisturizer with SPF 50 daily as part of your skincare routine to maintain healthy and youthful-looking skin.

Understanding SPF and Sunscreen Protection: Sunscreen protects against sunburn and skin cancer caused by harmful UV radiation. A broad-spectrum SPF 30+ sunscreen should be applied every 2 hours, especially between late morning and afternoon when UV rays are strongest.
