Do you really know about UV protection?
It’s the season again when you’re in search of a nice cold Americano or iced tea. In the stifling heat, all you want to do it avoid the blazing sun. When summer begins, the weather forecast calls for everyone to be cautious of UV rays. UV rays are hazardous to your health because they can cause sunburns, premature aging, and in severe cases, can lead to skin cancer. UV rays, which are in sunlight, can change your skin color, promote accelerated skin aging, such as freckles and wrinkles, and can causes skin problems, like hives, redness, and eczema. Therefore, it’s extremely important to apply sunscreen before going outside. However, many people do not know a lot about sunscreen. For the health of your skin, how much do you know about sunscreen?
Sunscreen is divided into two types, physical and chemical, that differ in their components and effect. Physical, also known as mineral, sunscreen contains inorganic chemicals, such as zinc oxide and titanium dioxide, which reflect and scatter UV rays to protect the skin. Physical sunscreens don’t glide on very smoothly, and leave a layer of white cast that doesn’t seep into your skin. Because of this, physical sunscreen can stay on the skin surface for a long time, so it’s important to thoroughly wash your face to avoid your pores from being clogged and causing breakouts. Chemical sunscreen contains organic chemicals, such as oxybenzone and avobenzone. This type of sunscreen protects your skin by absorbing and switching UV rays into heat energy. Unlike physical, chemical sunscreen is easier to apply; it also absorbs into the skin well, and has good UV blocking power. However, you should be cautious because some skin types are sensitive to the active ingredients in chemical sunscreens, which can lead to an allergic reaction.
It’s recommended to apply sunscreen at least 20-30 minutes before going out into the sun. In particular, in order for chemical sunscreen to effectively block UV rays, it should be applied in advance and given some time to adequately absorb into the skin. Sunscreen’s effectiveness doesn’t last as long as you’d think and is not perfect. Therefore, it’s good to reapply every 2-3 hours. Even if you’ve applied sunscreen, on those days when the UV index is high, it’s good to wear a hat, wear a long-sleeved shirt and pants and/or carry a parasol to help block the sun.
If you’ve ever look closely at sunscreen, you’ve probably seen something like “SPF 30++” written on the label. Do you know what this means? UV rays are divided into A, B and C. UVC is blocked by the earth’s ozone layer. Sunscreen’s SPF number indicates how much UVB is blocked, and the + sign indicates how much UVA is blocked. One + sign means it blocks 2-3 times more UVA than if you don’t apply sunscreen, two + signs indicate it blocks 4-7 times more, and three + signs means it blocks 8-15 times more. So, sunscreen with “SPF 30 ++” filters 97% of UVB in contact with your skin and blocks UVA at a rate of 4-7 times more than if you don’t apply sunscreen. However, higher numbers do not necessarily mean the blocking power is better. Since sunscreen causes chemical reactions, the higher the SPF, the more irritation and breakouts the sunscreen can cause. Experts recommend SPF 30, so be sure to reapply sunscreen throughout the day.
Just like makeup, it’s just as important to wash off sunscreen as it is to wear it. You should thoroughly wash your face to avoid irritated skin or breakouts from clogged pores due to any remaining product.
