How Harmful are UV Radiations for Your Skin?

Dermatologists and skin experts have for long been talking about the importance of sunscreens and why you should not step out of the house without it. How many of us take this seriously? Lots of people still think this is a hype to increase sales. If you are one such person, you should definitely understand all about UV rays and the reasons to never stay away from your sunscreen.

What are UV radiations?

With all the pollution and CFCs we send up the atmosphere, the ozone layer is depleting slowly. This means that more of sun’s rays reach earth and hence you are being exposed to more ultraviolet (UV) rays.

UV rays are a type of energy produced by the sun. This is basically of three types.

  • UVA rays
  • UVB rays
  • UVC rays

In these three types, UVC does not reach the earth’s surface and can be ignored. UVBs mostly affect the top layers of the skin. The results are skin burns and slight pigmentation. UVA is the largest source of skin damage and this penetrates deep into the skin leading to tanning, wrinkles, fine lines, premature aging, dryness and even skin cancer.

Protection from UV rays

Experts mention that the effect of UV rays are the worst between 10 AM and 4 PM. There are two ways you can protect yourself from the harm.

  1. Never step out of closed doors during this period
  2. Protect yourself when you go out in the sun

Protection from the sun

You can use hats and caps for the head, cover up your exposed arms and feet and try to control the effect of the rays. Sunglasses are also good options to protect your eyes from being damaged. However, the best protection comes from using sunscreens. These either absorb or deflect UV rays, thereby safeguarding your skin.

When you decide to get your sunscreen, the main feature to check is the SPF factor. Depending on your skin type and the intensity of sun’s rays, the SPF level varies. You can check for picking up the right sunscreen for your skin type. Getting this right is very important.

Applying sunscreens

You should be applying your sunscreen at least 20-30 minutes before you step out of your home. This way, the product gets enough time to start working. Do not be stingy with the application. Take a generous amount and apply all over exposed skin. If you are going to be outside all day long, make sure you reapply every 2-3 hours. In spite of how strong your sunscreen is, the effect is nulled after this time. If you have an oily skin tone, there are products that come with a matt finish and do not leave you greasy.

Even if you are not a fan of skin care products and cosmetics, sunscreens are basic requirements that you just should not stay away from. UV rays cause permanent damage and using sunscreens is your only option out.
