Um, no. The SPF number in sunscreen is how effective the sunscreen is in blocking out the harmful rays. So SPF 15 means that it is 15 times as effective as normal skin at resisting the UV rays that cause burns. It will normally say on the container how often to apply it.
UV radiation comes from the sun. If you stay indoors when the weather is very sunny you will be safe. Alternatively, wear suncream (also known as sunblock) everywhere you don't have clothes - hands, face, etc. Also, wear sunglasses with a UV filter or, failing that, a wide-brimmed hat to protect your eyes.NB: If it is sunny but also windy, the cool breeze may create the sensation of safety. This is false. Wear suncream anyway.Suncream comes in varying strengths, called "Sun Protection Factor" or SPF rating. For example, SPF15 means the damage to your skin is 1/15 of what it would have been without the cream. I'm not sure what the recommended SPF is, but I seem to recall 30 or so is enough as a general rule.It depends on your skin. Darker skin is safer. I don't think it is even possible for Afro-Caribbeans to get sunburn. Pale, red-haired people are most at risk. If you spend a few days in the sun your skin will tan (darken) to adapt to the sun. Then you won't need suncream as much. Suncream does not prevent tanning, so you might as well use as high an SPF as possible.
