The Basics of Sunscreen

Wednesday, April 20, 2016

The sun, it seems like such a harmless ray of sunshine. However, the sun exudes ultraviolet rays (UV) which is beneficial yet harmful. Not saying that one should stay clear of the sun at all times. It is actually quite good to get out and get some fresh air and sun. Nonetheless, it is when we are outside for too long that the sun's rays can start to take its effects.

Harmful Effects of the Sun's UV Rays:

  • Ages skin
  • Causes skin cancer
  • Causes sunburn
  • Damages immune system 
  • Damages eyes
  • Damages the DNA of skin cells

Main types of UV rays:

  •  UVA 
This type of ray is the most damaging ray to our skin, such as wrinkles. This is the ray that aids in aging.

  • UVB
This type of ray is the main ray that causes sunburns. This is also the ray to cause most skin cancers.

Now when choosing a sunscreen, pick a sunscreen that is broad-spectrum. This means that it will protect against most of the UV spectrum (UVA and UVB).

Myth or Fact?

  • If it is cloudy I do not need to use sunscreen.

This is a myth. Even if the sky is filled with clouds, this does not mean that the sun's rays do not peek through.

It is a fact that some types of clouds reflect UV and increases UV exposure. The important thing to remember is that even on cloudy days UV rays can get through.

Chemical Sunscreen

How does it work?

Chemical sunscreens work by absorbing the sun's rays like a sponge then changing the UV rays into heat and then releasing that heat from the skin.

What does it contain?

Chemical sunscreens contain organic compounds such as oxybenzone, octinoxate, octisalate, etc.

Physical Sunscreen

How does it work?

Physical sunscreens work by sitting on top of the skin to deflect and scatter damaging UV rays away from the skin.

What does it contain?

Physical sunscreens contain active mineral ingredients such as titanium dioxide or zinc oxide.

Chemical Sunscreen vs. Physical Sunscreen

There is a huge debate on which one protects better. Both chemical and physical do a great job at defending your skin against UV rays. It comes down to which one works better on your skin.
