Glossary

Cream or lotion capable of absorbing or reflecting ultraviolet rays given off by the sun. Sun screens contain a number of molecules in order to cover the widest possible spectrum of UV rays. Unfortunately, protection against the longest UV rays (UVAs) remains insufficient. It is important to choose a protection factor that covers both UVBs and UVAs, and that is higher than 30. When exposed to the sun, sun screen must be liberally and frequently - every 2 hours - applied to the skin since the molecules are destroyed as they absorb the UV rays.
