It has an SPF of 15 (I know because I have it)


You have only SPF 15 at home could you just apply it three times so that it is equal to SPF 45?

No it doesn't add up. It is still 15 no matter how much you apply it.

Does the SPF count?

"The Sun Protection Factor (SPF) displayed on the sunscreen label ranges from 2 to as high as 50 and refers to the product's ability to screen or block out the sun's harmful rays. For example, if you use a sunscreen with an SPF 15, you can be in the sun 15 times longer that you can without sunscreen before burning. Consumers need to be aware that SPF protection does not increase proportionally with an increased SPF number. While an SPF of 2 will absorb 50% of ultraviolet radiation, an SPF of 15 absorbs 93% and an SPF of 34 absorbs 97%." from http://www.melanomafoundation.org/prevention/facts.htm


What rays does SPF block?

Should be UVA and UVB. Read the labels, and use at least SPF 15 up to SPF 30 if you are very fair or freckle easily.


Will you get a good tan if you use spf 45 for 2 days and spf 30 for 2 days and spf 15 for the remainder while on Caribbean vacation and you have fair skin?

How long is the vacation? You are still apt to burn with fair skin if you are using SPF 15 for 7-10 days longer.


How long can you stay in the sun with SPF 15?

150 minutes

Try Aveeno. All of their mosturizers are fragrence free and have SPF in them.


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.


What SPF sunscreen you should use to exercise outside?

If you are exercising, it would be best to use a sunscreen with an SPF of at least 30 and reapply at least every two hours or after sweating.


What are the SPF levels of lotion for Coppertone?

Probably 5, 10, 15, 20, 25, 30, 35, 40, 25, and 50. Why do they would make lotion like SPF 5 and 10 while they already have SPF 50?
