Hot, hot, hot
The climate is changing. The earth is warming up, and it is seen as one of the greatest threats facing the planet.
It is really hot outside, so every time I go out I wear protective clothing or I put on sunscreen with SPF 15. Another tip I got is to wear light-colored clothes because it reflect sunlight better than dark colors.
Anyway, to truly protect your skin from UV rays, prepare, cover-up and use commonsense. Your skin will be healthier for it.
