 Protection against solar radiation

Sunscreens are substances applied to the skin to protect it against the action of ultra-violet (UV) rays of the sun. Sunscreens can be chemical (absorb UV rays) or physical (reflecting UV rays). Often the combination of physical and chemical filters to obtain a higher SPF sunscreen.

What is SPF?

SPF stands for Sun Protection Factor. Every sunscreen has a number that determines your FPS, which can vary from 5 to 50. SPF measures the protection against UVB rays, which is responsible for sunburn, but do not measure the protection against UVA rays.

How does the SPF works

The skin, when exposed to the sun without protection, takes a certain time to turn red. When using an SPF 15 sunscreen, for example, the same skin takes 15 times longer to turn red.

From the 15 FPS all filters are equal?

No. This is an idea that was published incorrectly. The sunscreen with SPF 15 blocks most of the UV rays. Actually when the SPF is increased, slightly the percentage of the protection is increased too.

How do I choose the SPF of my sunscreen?

The sunscreen should protect the skin avoiding the damage caused by solar radiation. If you use the filter that allows your skin turns red after exposure to the sun, this is a sign that the protection is not being effective. In this case, you should increase the FPS and then reapply the sunscreen with a shorter interval.

The minimum factor for adequate protection is 15 FPS, always applying the filter generously 20-30 minutes before sun exposure and reapply every 2 hours.

However, as the FPS is determined in laboratories, under special conditions, it is recommended to give a margin of safety, always using a sunscreen with SPF greater than or equal 30.

“Oil free”? Hypoallergenic? Understand your sunscreen.

The language used on the labels of sunscreens often leaves the consumer confused at the time of purchase. Learn below what means the most frequent terms and select those best suitable to your skin type:

  • Anti UVA and UVB: filters that protect against ultraviolet A and ultraviolet B.
  • Hypoallergenic: uses substances that usually do not cause allergies.
  • Free of PABA or “PABA free”: filters that does not contain PABA substance that has high power to cause allergies.
  • Oil free: filters whose vehicles do not contain oily substances. Are best suited for people with oily skin or skin prone to the formation of blackheads and pimples.
  • Non-comedogenic: filters that do not clog pores, thus preventing the formation of blackheads. Are also suitable for people with oily skin and skin prone to the formation of blackheads and pimples.

Attention: sunscreen that protects leaves no burn.

Do you have sunscreens of the last year at home, then do you think of reusing them to avoid throwing them away?
Be careful! The filters and most of the other substances within the sunscreens, lose totally their effectiveness after 12 months of opening, or earlier if the product has been poorly preserved!

Always use sunscreen to avoid skin burns, cancer and premature aging! Follow the tips and enjoy the summer!

With love!
