How to act

We all love warm weather in the summer - or even in the spring when we are lucky, and almost all people want it. We spend a lot of time enjoying the sun's rays, but, of course, if you're smart, always use sunscreen before going out into the sun. Some people shed last year's creams, while others go shopping to buy new ones. But how should we act? Can we use sunshine last year? Does it have the same effect?

Sunscreen

When you buy a new cream against the sun, the label usually says the product lasts about 12 months after the opening. Creamers say SPF can be halved after one year. According to them, this happens because the product constantly comes into contact with UV radiation, oxygen and heat during the summer. That's why the lotion becomes less effective over time, they explain.

However, Ann Lievens thinks this is probably a bit exaggerated. She explained to HLN that it is unnecessary loss of so many open creams if they disappear after a year. Lievens wanted to know the truth about it and therefore, tested whether the SPF of an annual bottle of a cream was reduced or not.
