There are two categories of UV light -- UVA and UVB -- that we consider in terms of sunscreen. UVB causes sunburn, and UVA has more long-term damaging effects on the skin, like premature aging. SPF, or sun protection factor, numbers were introduced in 1962 to measure a sunscreen's effect against UVB rays.
SPF stands for Sun Protecting Factor. It is a measure of how good the sunscreen is to protect against the UV rays of the sun.
The higher the number the greater the protection
its the spf amount
The SPF number on a sunscreen label stands for Sun Protection Factor. This means if the SPF is 30, this means you can stay in the sun 30 times longer than you would be able to without wearing sunscreen.
On sunscreen bottles, SPF stands for 'Sun Protection Factor'.
SPF means Sun Protection FactorSunscreen and SPF can be confusing, we'll explain the differences and what works best and will protect you from sunburn as we move into the summer months.
Sun Protection Factor
it is sun protection field
It is proven that people with light skins, are best protected when using a SPF 50 sunscreen and upwards. Sunscreen has SPF ranging from 8, all the way up to 70. Depending on your skin tone, it is better to be too careful by protecting with a high number SPF.
Assuming the question is asking about sunscreen SPF, it stands for sun protection factor. This is put on sunscreen bottles to show the consumer how strong the sunscreen is.
boring It means thats the SPF protection from the solar rays(for your skin)...always get 30+.... the higher the number, the better protection :)
I have a bottle of spray on sun screen, it had an SPF rating of 110. I have very white skin ;) Previous answer: As far as I've seen 100. It must also be kept in mind that after a particular number the SPF does not count. What counts is whether the sunscreen gets washed out due to sweat or water and whether it gets wiped out due to clothing. If so then even if you have a SPF 200 sunscreen, you will need to reapply as required.
No. SPF 30 lets in 1/30 of burning UV rays, while SPF 50 lets in 1/50. Adding the two together is pointless and would not result in high levels of skin protection.
SPF stands for Sun Protection Factor. A higher SPF means your sunscreen is able to protect you from the sun more. It is recommended to use at least an SPF-15 sunscreen. You can see on the back of sunscreen what the active ingredients are. Those ingredients provide the sun protection factor in the form of a number.
100, because it offers more UV protection.
The highest SPF I have located is 110 for both Face and Body: Face: Neutrogena Age Shield Face - SPF 110 Body: Banana Boat Kids Max Protect & Play Continuous Spray Sunscreen SPF 110 Banana Boat Ultra Defense Sunscreen Lotion SPF 110 Banana Boat UltraMist Sport Performance Sunscreen SPF 110
A million SPF
"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
The protecting capacity of a sunscreen is measured by the term SPF (sun protecting factor). A higher SPF sunscreen will protect you from the sun more. It is recommended to use at least SPF 15 sunscreen or higher. Sunscreens can also help prevent photoaging.
It does. The higher the SPF, the higher UV protection it contains. Let's say you have a sunscreen with a 30 SPF and one with 60, the one with 60 offers more protection.
"The sun protection factor of a sunscreen is a laboratory measure of the effectiveness of sunscreen --- the higher the SPF, the more protection a sunscreen offers against UV-B (the ultraviolet radiation that causes sunburn)."
it would be............spf 50
Yes. The purpose of sunscreen is to lengthen the amount of time you can be in the sun before tanning starts. Also, SPF 15 provides the maximum amount of protection. Any higher SPF number does not provide any additional protection.
