Sunscreen is a must for everyone in their day to day life. There are many articles on the web which state the importance of using sunscreen. But still, there are lots of myths circulating in our society which needs to be busted with well-known information.
Today’s blog post is an in-depth article about sunscreen facts and useless myths which we are listening from ages.
Myth: The amount of sunscreen does not matter at all.
Fact: If you apply only a pea-sized amount on your face and neck, it will not provide enough protection. Your skin will still suffer from damage caused by UV rays. According to Doctors, half teaspoon of sunscreen is an adequate amount for our face and neck. One full spoon for your arms and 2 spoonfuls for your legs.
Myth: Sunscreen with higher SPF don’t need reapplication.
Fact: Even if we have applied a sunscreen with higher SPF but we touch and also wipe off sweat from our face persistently. Which in turn, decreases the concentration of sunscreen on the skin. So, reapplication of sunscreen after 2-3 hours provides protection to our face from harmful UV rays.
Myth: Sunscreen with higher SPF protects your skin better.
Fact: A sunscreen with SPF 30 blocks 97% of harmful UV rays whereas a sunscreen with SPF-50 blocks UV rays up to 98%. This means sunscreens above SPF 30 are just a marketing gimmick.
Myth: Sunscreen is just for sunny days or when you are out in the sun.
Fact: Whether it is a sunny day or a rainy day, Sun’s harmful rays are always active during daytime. Even when you are inside your home or at the office, you are still in contact with UV rays.
Myth: SPF is the only factor to look out when you are buying a sunscreen.
Fact: SPF only protects your skin from UVB rays which harm only the topmost layer of skin. While UVA rays damage the skin up to 3 layers. PA factor on sunscreen defends your skin from UVA rays. If you are not able to find PA factor on a sunscreen, look for the term ‘broad-spectrum’. A broad-spectrum sunscreen is able to protect skin from both UVA & UVB rays.
Myth: Waterproof sunscreen does not need to be reapplied.
Fact: Waterproof sunscreen loses their effectiveness after 30-40 minutes in water. Waterproof sunscreen needs reapplication after every hour if you are in water for a long duration.
Myth: SPF-30 sunscreen provides twice the protection as SPF-15 sunscreen.
Fact: SPF-15 sunscreen provides 93% of protection from UV rays while SPF-30 sunscreen provides 97% of protection. So, no point in comparing sunscreens based on SPF indication.
Myth: Sunscreen inhibits our body to absorb Vitamin D.
Fact: Using sunscreen does not block body’s ability to absorb Vitamin D from the sun. In fact, your body doesn’t need more than 10-15 minutes a day under the sun to make Vitamin D.
Myth: I can stay under the sun for a longer duration if I have applied sunscreen.
Fact: Sunscreen with SPF-30 blocks only 97% of harmful UV rays which means if you are persistently under the sun for a long period. Your skin is getting affected by 3% of unblocked UV rays.
