Summer has arrived, which means long swims, lazy days, and catching some rays. However, though many of us adore the sun, the sun does not adore us.

It’s a bad relationship that can hurt our skin in the long run, since spending more time in the sun exposes us to harmful ultraviolet (UV) radiation. Which increases our the risk of developing wrinkles, premature aging, and even skin cancer.

What you should know about UVA & UVB rays:

To debunk the sunscreen myths, we need to understand the forms of Ultraviolet: UVA and UVB rays that can affect the skin after exposure.

  • UVA light is known for its long waves that penetrate the dermis, which is the thickest layer of the skin.
  • Unprotected exposure to UVA rays can lead to wrinkles, skin aging, and suppressed immune system.
  • UVB rays have a shorter wave, which can reach the top layer of the skin causing sunburns. Frequent exposure to UVB rays may cause permanent skin damage over time and can play a key role in developing skin cancer.

We picked for you the top MYTHS and decided to reveal the TRUTH behind them!

1- Sunscreen is not needed indoors

Scientists discovered that compact fluorescent bulbs (CFLs) released sufficient UVA rays that caused damage, in a study on human skin cells. And a follow-up study from the same research group noticed that LED lighting was safer for the skin. Yet, no one can take that risk!

2- Sunscreen is waterproof

Sunscreen labeled as water-resistant may look to be waterproof. No sunscreen can be 100% waterproof. After swimming, people should reapply sunscreen and wait at least 10 minutes for it to dry before returning to the water.

3- Makeup can protect

It’s true, makeup can protect your face from the sun, yet it is not much and it is not a replacement for a solid sunscreen. Makeup can work as an extra layer of protection, and not the only layer of protection.

4- You don’t need SPF for your lips

The FDA advises using sunscreen on all exposed skin, including lips, and of course, avoid getting it inside the mouth or eyes.

5- It’s cloudy, no need for sunscreen

Although the sun is hiding behind the clouds, it doesn’t mean it’s not there. Up to 80% of UV rays can get through the skin, which can lead to sunburns.
