There are some common myths
surrounding sunblock that people should be aware of before buying the
sunscreen.
Understanding the fact about
sunscreen can support people to use sunscreen properly.
UVA vs UVB
UVA light has a longer wave that
penetrates the thickest layer of skin, called the dermis. Unprotected exposure
to UVA rays can lead to skin aging, wrinkles, and a suppressed immune system.
UVB rays have a shorter wave. It
causes sunburn and also responsible to cause Skin cancer.
Here are the 11 common misunderstandings about sunscreen!
1. Sunscreen is not always necessary
Many people believe that sunscreen
is not necessary when they are not exposed to sunlight too much and it's
cloudy. The truth is that anytime the body is exposed to light from the sun, it
is exposed to UV rays and causes sun damage. It is best to cover the exposed
skin with sunscreen and use a hat or scarf to protect your skin.
2. Sunscreen will avoid the body from
retaining vitamin D
Calcium is one of the building
blocks of bone. Vitamin D helps the body to absorb calcium. Vitamin D also has
a role in the nerve, muscle, and immune systems. After exposure to sunlight,
our body forms vitamin D naturally.
People believe that using
sunscreen would prevent a person from getting the proper levels of vitamin D.
However, sunscreens lose their effectiveness over time, and it is likely a
person will forget to put sunscreen on every time they see the sun. Hence sunscreen
won’t prevent the body from absorbing Vitamin D. Scientists and dermatologists
suggest that at least 5 to 30 minutes of sun exposure per day can create the
proper amount of vitamin D in the body.
3. People with dark skin don’t need
sunscreen
Some people believe that people
with dark skin do not need sunscreen because they have more melanin which
diffuses UVB rays and protects their skin. Wait...what about UVA? UVA cannot be
blocked by Melanin which means even dark skin people need sunscreen to protect
their skin from UVA rays which is responsible to cause skin cancer.
4. Sunscreen causes health problems
This myth is because of
Oxybenzone, one of the active ingredients in sunscreen. Researchers exposed
rats to oxybenzone which results in a serious negative side effect. Later they
said the level of exposure was high that’s why it caused health issues in rats.
Their calculations demonstrated
that these results were unattainable in humans even those who use sunscreen on
a regular basis. There are no published researchers which demonstrate the toxic
effect of sunscreen in Humans.
5. Sunscreen never expires
Some believe that sunscreen never
expires. The active ingredients in sunscreen will breakdown over time. Using
the expired one is of no use; it won’t protect the skin.
6. Sunscreen is waterproof
Sunscreen labelled as
water-resistant maybe appear like waterproof. But the fact is no sunscreen is
100% waterproof.
7. One application of sunscreen lasts
all-day
Many people think that sunscreen
will protect their skin all day, but the fact is screen breaks down when it is
exposed to sunlight. It will last only for 2-4 hours.
8. All sunscreens are the same
People misunderstand that all the
sunscreens are the same, and they will do the same job. There are different
ingredients used in different sunscreens. Their protection level varies. The
important consideration is SPF (Sun Protection Factor).
9. You cannot tan while wearing sunscreen
Sunscreen will protect your skin
from UV rays. However, it may not protect your whole body. It is possible to
get tan even though if you applied multiple layers of sunscreen. Tanning is the
natural body’s response to UV rays. To avoid a tan, it is best to apply
sunscreen and cover up with a hat and long clothing.
10. Sunscreen works better than covering up
Many people believe that applying
sunscreen will make their body invincible to the sun. But the truth is covering
up your skin with cloth or hat is much better than sunscreen.
11. Makeup is enough to protect the face
Makeup is s not a good replacement
for Sunscreen. It provides an extra protective layer, not just only layer.
