SPF, or Sun Protection Factor, measures the effectiveness of sunscreen in protecting the skin from UV radiation, specifically UVB rays that cause sunburn. Sunscreen, often referred to as sun cream, contains active ingredients that absorb or reflect these harmful rays, with the SPF rating indicating how long it can protect the skin compared to unprotected skin. For example, an SPF of 30 means it would take 30 times longer for the skin to burn than without protection. Therefore, SPF is a critical aspect of sun cream formulations, guiding consumers in selecting the appropriate level of protection.
What else can I help you with?
Do you have to put on factor 10 suncream every ten minutes and factor twenty every twenty minutes?
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.

How can you protect ourself from uv radiation?
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.

What is the highest SPF facial sunblock can be purchased in?
It was probably SPF 30 because that blocks 96.7% of UVB rays. SPF 50 blocks 98% so you aren't really getting that much more protection than the SPF 30. Neutrogena has a SPF 100 but it really isn't necessary because as I said, SPF 30 is already blocking a significant amount, and SPF 50 doesn't even make that much more of a difference. Just for your information, SPF 100 blocks 99% of UVB rays so it REALLY doesn't do much more than SPF 50.
