SPF what is it? Guide

We have written many times about the importance of not only caring for, but also protecting the skin. Each of us should remember to protect our complexion from harmful external factors, including sunlight. Here the title SPF plays an important role.

What exactly is SPF? What should each of us know about this topic? We encourage you to read!

What is SPF?

As announced, let’s start with an explanation of what SPF is. SPF when expanded, stands for Sun Protection Factor, which we translate as Sun Protection Factor. SPF is the international symbol for the level of protection of the skin from the sun’s UVB radiation.

According to the recommendations of the European Commission, there are 4 levels of SPF protection, these are:

  • Low, very mild UVB protection – SPF 6 and 10,
  • Medium UVB protection – SPF 15, 20 and 25,
  • High UVB protection – SPF 30 and 50,
  • Very high UVB protection – SPF 50+.

SPF 20, 30, 50+ – what does it mean?

It is imperative that we emphasize that creams with SPF do not provide 100% protection from the sun’s rays. Even SPF50+ cream does not absolve us from being cautious and does not completely eliminate the risk of burns. The SPF index, however, tells you how long it takes for sunburn to occur. The length of time after which we are in danger of burning depends on individual tolerance, as well as the SPF index. Let’s use an example. If in the absence of sunscreen the erythema on our skin appears after about 30 minutes, after applying SPF10 cream it will appear after about 300 minutes.

SPF vs. UVA protection

Above we mentioned the levels of UVB protection. However, it is imperative that we keep in mind the second type of harmful solar radiation, UVA. UVA rays are very dangerous to our skin. They penetrate the deep layers of the skin and cause photoaging. No system has emerged for the level of UVA protection – as is the case with UVB radiation. Moreover, manufacturers are not obliged to put information on cosmetics about such protection. However, it is assumed that the SPF cream should provide at least ⅓ of protection against UVB. That is, for an SPF30 cream, UVA protection should be a minimum of 10.

Sun protection – why is it so important?

SPF cream should be used all year round, not just on hot days or while at the beach. The sun shines all the time, even in winter. Lack of protection can result:

  • acceleration of skin aging processes,
  • loss of skin firmness,
  • discoloration,
  • overdrying,
  • damage to collagen fibers,
  • increasing the production of free radicals in the skin, which can even lead to cancerous lesions, such as melanoma.
