It’s summer time! This is the perfect time to be flaunting your perfect bikini figure at the beach. But hold your horses babes! Don’t forget to protect your youthful skin while having your fun and games! Repeated or prolonged exposure to the sun’s ultraviolet A (UVA) and ultraviolet B (UVB) radiation leads to skin cancer. Your skin also starts to age prematurely if you don’t shield it from the harmful rays of the sun. You can find out more about the sun and premature aging here.
Sun Protection Factor, more commonly known of SPF, measures the extra length of time a sunscreen will protect your skin from reddening or burning. A generally the higher the SPF, the more protection you have. For example, without sunscreen, you can usually stay in the sun without reddening or burning for about 20 minutes. Theoretically, a sunscreen with SPF15 should increase your skin’s protection levels by 15 times. This means that your skin should be able to last for about 5 hours, instead of 20 minutes. However, that does that mean that if you apply a sunscreen for SPF15, you will definitely be fully protected during the 5 hours. Sunscreen will wear off after a certain time.
It is important to know that layering products with sunscreen doesn’t give you more protection against the sun. On the contrary, you are only given the protection of the highest SPF. For example, you use 3 sunscreens of SPF 15, 30 and 60 at the same time. This does not mean you have SPF105 worth of protection. You are only protected with SPF60. It is also not advisable to skimp on sunscreen when you are indoors. UV rays are still able to penetrate the windows and glass. Similarly, it is also not advisable to skimp on sunscreen on cloudy days.
