Going Out in the Sun? Make Sure You’re Sun Protected

Summer’s here again and it is great to be outdoors and catch a dose of Vitamin D. Although it’s nice to feel the sun’s warmth on our skin, too much sun exposure can be dangerous to our health. That is why putting on some sunscreen is essential when going out under the sun.

To find the right sunscreen for you, here are some important terminologies that would help you pick the right sunscreen:

  • Sun Protection Factor (SPF): We usually see this on every sunscreen label in the market. But what does SPF really mean? SPF measures how well a sunscreen can protect the skin from sunburn. Sometimes we would see SPF of 15, 30, 50 on the labels. SPF 30 does not protect your skin twice as SPF 15 would; rather SPF 15 blocks 93% of UVB rays and SPF 30 blocks 97% UVB rays.
  • UVA: UVA is a type of ultraviolet radiation which is not absorbed by the ozone layer. It penetrates deeply through our skin and can cause our skin to age prematurely.
  • UVB: UVB is another type of UV radiation that is partially absorbed by the ozone layer. It is usually the cause of sunburn because it affects mostly the surface of our skin.
  • Sunscreen Ingredients: Here is a list of FDA approved sunscreen ingredients. Chemical ingredients oftentimes causes skin reactions like burning, tightening, dryness, and itching, while physical ingredients do not cause any skin reactions.

The next time you’ll be walking, running, camping, or swimming, don’t forget to put on some sunscreen 15-30 minutes before you leave the house.

Have a great summer by keeping your skin healthy!
