WHAT IS THE SPF PROTECTION INDEX?

SPF stands for "Sun Protection Factor". It is a measure used to indicate how effectively a sunscreen product can protect the skin from the harmful effects of the sun's ultraviolet (UV) radiation. Specifically, SPF measures the level of protection against UVB rays, which are the ones that cause sunburn.

The higher the SPF number, the more protection it provides.

Here is a general guideline of what SPF numbers mean in terms of protection:

o SPF 15: Blocks around 93% of UVB rays. It is recommended to reapply after 15 minutes when in the sun.

o SPF 30: Blocks around 97% of rays

UVB shots. It is recommended to reapply after 30 minutes when in the sun.

o SPF 50: Blocks around 98% of UVB rays. It is recommended to renew after 50 minutes when in the sun.


Note that no sunscreen product can offer 100% protection.

The use of a broad-spectrum sunscreen with an SPF of 30 or higher is recommended to provide adequate protection from both UVB and UVA rays. It is important to reapply the protective product every two hours, or more often if you swim or sweat, to maintain its effectiveness.

Remember that SPF only indicates protection against UVB rays, so it's also critical to look for a sunscreen product with a broad spectrum of protection that offers protection against UVA rays, in order to ensure complete protection from the sun.
