1 doctor agrees

In brief: That is not true

In the U.S., there are several ingredients commonly used in today's sunscreens.
If the sunscreen protects against both UVA and UVB ultraviolet radiation from the sunlight, then it does work. One can get an idea of how well it works by looking at the SPF number (for example, SPF 8, SPF 15, SPF 30). However, a person may see little difference in effect among high SPF's, such as SPF 40 vs. SPF 60.
