We distinguish the following parameters of the effectiveness of UV sun protection cosmetics: SPF, UVAPF, critical wavelength, UVA:UVB ratio, Water Resistance and Very Water Resistance. 

In order to declare that a cosmetic protects against UV radiation, two factors must be tested:

  • SPF (Sun Protection Factor) – for UVB radiation
  • UVAPF (UVA Protection Factor) – for UVA radiation

The SPF factor should be given as a numerical value and an effectiveness category:

  • 6,10 – low (obtained value in the test = 6 – 14,9)
  • 15,25 – mean (obtained value in the test = 15 – 29,9)
  • 30,50 – high (obtained value in the test = 30 – 59,9)
  • 50+ very high (obtained value in the test = 60 ≤ )
The UVAPF factor should be at least 1/3 of the SPF value. This parameter is referred to as the UVA:UVB ratio.

Sunscreen is more valuable when it is waterproof.

The method for determining the water resistance of a sunscreen cosmetic – Water Resistance (WR) – is based on comparing the sun protection factor of the product after two 20-minute water baths at 29 ± 2°C to the sun protection factor obtained before immersion in water.

For cosmetics intended for children, we use a method to determine the high water resistance of the cosmetic – Very Water Resistance (VWR). It differs in that the high water resistance test uses not 2 but 4 baths.

The study must meet appropriate statistical criteria. The SPF value after bathing cannot be less than a specified percentage of the average SPF value before exposure.

In order to ensure reliable test results, we always use reference material (reference product) in the above methods.
