Searching for the origins of something can sometimes present a challenge. A case in point: when we wanted to find out who invented sunscreen, we ended up with light bulbs. They have more in common than light alone.

Sunlight is the source of life on Earth. But it is not only the sun that is responsible for our well-being. Artificial light is also playing an increasingly important role in our everyday lives.

When a new cosmetic product is launched on the market, it is time to switch on the advertising megaphone – loudly. The product can do this, that and the other. Before that can happen, however, researchers and developers need to back up the advertising claims with validated tests and results . Customers and end users have to be able to rely on the statements made about the products. 

When buying sunscreen, the majority of consumers pay most attention to the sun protection factor. This value is tested directly on humans via what is known as an in vivo process. However: A high sun protection factor alone does not mean a sunscreen is good.

We all know that the sun is responsible for life on our planet. For the most part, its rays also make us feel good and put us in a happy mood. Even so, we want to continue raising people's awareness of the need for sun protection, because sadly, skin damage and skin diseases caused by UV rays are widespread.
