UV stands for Ultra Violet, and UV light is harmful to your skin if your skin is exposed for long enough. Sunscreen tends to block, absorb, or reflect UV rays, therefore protecting your skin. The strength of the sunscreen can differ, and that's why you see labels on sunscreen bottles saying "25 SPF" or "35 SPF", the higher numbers indicating stronger sunscreen for longer or more intense exposures.
