Importance of Sunscreen

It is 2019 and the environment is getting more and more polluted. As we know the ozone layer is getting thinner by the day. And we are exposed!!!

Let me explain what the ozone layer is.

Our planet has an atmosphere which is mainly divided into four regions. They are Troposphere Stratosphere Mesosphere and Thermosphere. Ozone layer resides in the Stratosphere. It has a high concentration of Ozone gas (O3). There are continuous reactions which turns ozone into oxygen and Oxygen back into Ozone. These reactions require energy which is gained by absorbing the Ultra Violet or UV rays that comes from the sun. Generally the Ozone layer protects the earth form that harmful radiation.

We cannot act normal

Human has a very sensitive skin. Due to the thinning of the Ozone layer the problem has increased. Now we cannot depend on the natural protection. We have to have an extra protective layer. It does not matter you are from which continent you are gonna have to start using sunscreen.

What is sunscreen?

Sunscreen is a lotion which protects our skin from the UV rays. That is the most simple explanation. With the use of sunscreen we can protect ourselves from the harmful radiation.

How does sunscreen protects us?

A sunscreen lotion contains both organic and inorganic materials. Inorganic ingredients like zinc oxide or titanium oxide reflect or scatter ultraviolet (UV) radiation. Organic ingredients like octylmethoxycinnamate (OMC) or oxybenzone absorb UV radiation, dissipating it as heat.

Why should we use sunscreen?

We should use sunscreen if we are concerned about our health. The UV radiation can cause skin cancers. Specially UVA radiation. Also it can cause Phytophotodermatitis ( commonly known as berloque dermatitis or margarita photodermatitis )

Beauty Benefits

But using sunscreen could help us to develop our beauty in a way. Specially if we do not want any discoloration. Which many people face after a long day at the out side. Specially women in tropical countries use bleach or whitening lotion as a remedy for the discoloration. If they can use sunscreen daily they do not want to use bleach.

Many cosmetics products have SPF value. Which means the certain products contain sunscreen. Because using cosmetics in outdoors could be challenging or people simply ignore to apply a layer of sunscreen before make up because they do not intend to go out side. So women do not need to apply an extra layer.
