What is SPF

SPF : Sun Protection Factor measures how well sunscreen can protect the skin from harmful UVB rays, which cause sunburn and contribute to skin cancer.

The SPF number indicates the level of protection the sunscreen provides compared to unprotected skin. For example, sunscreen with a 30 means that it will take 30 times longer for the skin to redden from UVB exposure compared to not wearing sunscreen. 

SPF & UVB

It’s important to note that SPF primarily measures protection against UVB rays and not UVA rays, which can also cause skin damage. Therefore, it’s recommended to use a broad-spectrum sunscreen, which protects against both UVA and UVB rays.

SPF30+ indicates that the sunscreen has been tested and determined to provide a sun protection factor of 30 or higher. The “30+” symbolises that the Sun Protection Factor level is at least 30 but may be higher, offering adequate protection against UVB rays. Sunscreens with SPF30+ are designed to block a significant amount of UVB radiation, allowing individuals to stay in the sun without experiencing sunburn 30 times longer than if they were not wearing sunscreen. The PLUS sign in the 30+ indicates a sun protection factor of 30 or higher but lower than 40.

SPF50+ indicates that the sunscreen has been tested and determined to provide a very high level of sun protection factor of 50 or higher. The “50+” symbolises that the Sun Protection Factor level is at least 50 but may be higher, offering powerful protection against UVB rays. Sunscreens with SPF50+ are designed to block a significant amount of UVB radiation, allowing individuals to stay in the sun without experiencing sunburn 50 times longer than if they were not wearing sunscreen. The PLUS sign in the SPF50+ indicates a sun protection factor (SPF) of 50 or higher, emphasising that the actual Sun Protection Factor is above 50. 50+ is higher than a 50 but lower than 60. 

Testing:  These claims can only be made based on the rigorous testing conducted by an authorised regulatory body for sunscreen testing. It’s essential to rely on sunscreens that have undergone proper SPF testing to ensure that they deliver the level of protection indicated on the packaging.

Can any sunscreen provide provides 100% protection?

No sunscreen can block 100% of the sun’s rays. To ensure adequate protection, sunscreen must be applied generously and reapplied regularly, especially after swimming or sweating. Understanding the Sun Protection Factor and its application is vital in maintaining proper sun protection and minimising the risk of sun damage. It’s essential to use other sun protection measures alongside sunscreen, such as seeking shade, wearing protective clothing, and avoiding peak sun hours. These measures, when used in conjunction with sunscreen, provide a comprehensive approach to sun protection, especially in very sunny or high-altitude environments, making you feel secure and well-informed about your sun protection strategy.
