Sunscreen shopping can be really confusing. A lot of people think that the higher the SPF the better the sunscreen is that is not always true. Lotus Professional sunscreen has a lot of sunscreens with different SPF numbers. For example their SPF 50. Their SPF 70 sunblock. Comparing these two can help us understand when a higher SPF really makes a difference.
What do SPF numbers actually mean?
SPF measures how well a sunscreen protects us from UVB rays. These are the rays that cause sunburn. The thing is, the the SPF number, the smaller the difference in protection. So comparing two sunscreens is not about which one has the bigger number.
Here is what the numbers mean:
* SPF 30 blocks 97 percent of UVB rays.
* SPF 50 blocks 98 percent.
* SPF 70 and above blocks a little more, but not more than 99 percent.
The SPF 50 Sunblock Mist is a sunscreen. It is easy to apply and does not feel heavy on the skin. This makes it great for use. You can wear it under makeup. When you are active outside.
The Ultra Protect SPF 70 Formula is stronger. It is for people who're outside for a long time or who have skin that is very sensitive to the sun. It has sun filters, which can give you extra protection in certain situations.
Who needs the SPF?
Most people do not need a SPF for everyday use. SPF 30 to 50 is enough for people who're only outside for a short time.. If you are going to be outside for a long time or if you have skin that is sensitive to the sun you may need a higher SPF.
Here are some examples:
* If you are outside for a short time SPF 30 to 50 is fine.
* If you are going to be outside for a time or if you are going to be in the water you may need a higher SPF.
* If you have skin that's very sensitive to the sun you may need a higher SPF.
The thing that really matters is how you apply the sunscreen. If you do not apply enough it does not matter what the SPF number is. You need to apply a layer and reapply it every couple of hours.
In the end choosing a sunscreen is not about the SPF number. It is about how time you spend outside and how sensitive your skin is. For people SPF 50 is enough.. If you need more protection a higher SPF can be helpful. Just make sure you apply it correctly.
