UVB rays can cause burns and skin spots, while UVA radiation accelerates premature aging. Both types of radiation are linked to the development of some types of skin cancer, warn ZPS. The ability to protect the skin from UVB rays is indicated by a sun protection factor (SPF) on the packaging.
A product with a sun protection factor of 30 must prevent the passage of 96.7 percent of UVB radiation, while a factor of 50 blocks 98 percent. Beach photo: Bob. According to the European Commission’s recommendations, UVA protection should reach at least one-third of the stated UVB protection factor.
The packaging must, however, indicate the information on UVA protection, but unfortunately, the precise value of this information is not mandatory. Comparative tests carried out by consumer organizations are therefore of great importance, as they also provide consumers with a basis for comparison.
