If you're interested in looking younger and with skin cancer on the increase, it's important that you use sunscreen to protect yourself whenever you can. However, with so many different types of sunscreen and SPF protection it's not surprising that you may become confused. Let's see if we can take some of the guess work out of it.
In this article, you're going to find out exactly what SPF means, plus you're going to find out 3 top tips to ensure that you're getting the skin protection from your sunscreen that you're expecting. After all, if you're wanting to look younger and you're using wrinkle creams to prevent the formation of wrinkles, how much more effective would you be if you could reduce premature aging caused by the sun?
So firstly, what does SPF mean?
SPF stands for sun protection factor. Let's look at how SPF (or sun protection factor) is calculated. All sunscreens on the market use a formula that is FDA approved. The SPF rating calculates the amount of time it takes to sunburn without sunscreen against what it takes with sunscreen. So for example, if you burn in 10 minutes and you have a sunscreen with an SPF of 15 you will now be able to stay in the sun for 150 minutes before you burn.
Three tips here about using sunscreen to ensure that you're getting to help you:
Firstly, when choosing an SPF remember to use how long it takes to burn depends on which art of the day you're in the sun. The hottest period from 10 am to 2 pm, so your burn rate during this period is higher, so a SPF 30 sunscreen will not last you as long as it would if you were out in the sun at 4 or 5 pm. Also remember, the higher the altitude the quicker you will burn.
Secondly, the SPF rating of your sunscreen is calculated by studies that assume that you're going to put the sunscreen on as thickly as it was applies in that study. Did you know that it's assumed that sunscreen is applied to an internationally accepted thickness of 2 mg/square cm, whereas in a study of real life people applying sunscreen, found that they only applied a thickness of 0.39 mg/square cm. So apply enough of the cream to have the desired effect.
Thirdly, the SPF rating of a cream will only be maintained if you apply the cream at the right time. What do I mean? See a sunscreen takes about 15-30 minutes to properly absorb into the skin to provide maximum protection, so make sure you apply the cream 15-30 minutes before you go into the sun.
But how often should you reapply the sunscreen? The instructions commonly say 2-3 hours after application, but in a study in the UK, it was shown that in fact reapplying 15-30 minutes after you get into the sun, not 2-3 hours after, will provide you with the maximum protection. Also, reapply after going swimming, rubbing the skin or using a towel.
And remember, there are sunscreens that protect against just UVB rays or sunscreens that protect against both UVB and UVA rays. You should choose sunscreens that provide both UVA and UVB protection because both types of rays will cause skin problems now and in future.
Finally, realize that sunscreen has its flaws as you've just learned, so it's important to not only rely on sunscreen. The best policy is to stay out of the sun at peak hours, and to wear a long sleeved top and a wide brimmed hat when you are out in the sun.This helps up the SPF rating of your skin a lot!
So there you have it.You now know what SPF means and the important tips to follow to make sure that you're getting the protection you're expecting. Steer clear of the sun if possible, but if you are out in the sun, stay protected to prevent premature aging of your skin, and enjoy having younger looking skin at any age.
