Escoge el fotoprotector adecuado: ¿qué significa SPF y el número?

Choose the right sunscreen: what does SPF and the number mean?

Many cosmetics incorporate sun protection and indicate it with the acronym SPF or FPS. Do you really know what they mean and which is the most suitable sunscreen for your skin?

What is SPF?

The acronym SPF or FPS that appears on some cosmetics means Sun Protection Factor. They usually appear accompanied by a number. This indicates the level of protection that the product provides against harmful solar radiation (UVB). It is wrong to think that it corresponds to the time in minutes that it protects the skin with its application. In fact, the number specifies how many times it increases the skin's natural protection against burns. From this, you can extract the approximate time that your skin would last in the sun without burning. We'll tell you then!

How to choose the most suitable SPF?

To choose it, look at:

  1. Minutes that your skin can last naturally without burning , without applying protective cream).

  2. Number indicated on the container label , that is, the number of times more than the cosmetic will protect your skin.

Multiply the how long your skin lasts based on the SPF number. The result is the approximate time that your skin will be protected with the sunscreen. For example, if you usually burn after 15 minutes of exposure and you apply SPF20, the time it will take to burn is 300 minutes (15min X 20 times = 300 min).

Careful, IT IS NOT AN EXACT TIME ! No sunscreen provides total protection. In addition, factors such as sweat, contact with water, correct application, radiation intensity, perspiration, etc. have an influence. which reduce it, which is why we recommend applying sunscreen more regularly during exposure.


  • As reported by the Sun Protection Guide of the Ministry of Health, the general council of official associations of pharmacists and the Spanish Association against Cancer (aecc), there are different ways to specify the SFP. In Europe, the COLIPA method is usually used and determines them in the following way:
      • Low: 2-4-6
      • Middle: 8-10-12
      • Height: 15-20-25
      • Very tall: 30-40-50
      • Ultra SPF: 50+
  • Use an SPF higher than 15! A lower one protects from burns but not from aging or skin cancer.

  • Apply high protection if you do outdoor sports or if you are going to be exposed to the sun a lot!

Protect your skin daily even if you are not going to be directly exposed to the sun!
We recommend the GGcare Moisturizing Facial Cream with Sunscreen . It will hydrate and protect your face and will also add a touch of color to your skin.
