While UVA are the aging (wrinkle-causing) rays UVB are the BURNING (Skin-cancer causing) rays. Make sure the sunscreen you are using covers you from both – it needs to say BROAD SPECTRUM to be effective.
2. HIGHER SPF JUST MEANS LONGER PROTECTION NOT STRONGER
I’m certain the vast majority of people are unaware of this fact. SPF doesn’t refer to the strength of your protection but simply the length of time you are potentially protected. So if you are using SPF 10 it means you will get ten times the amount of time in the sun than it would usually take for you to burn. SPF 30 means 30 times and so on.
3. AS SOON AS YOU SWIM OR SWEAT YOU NEED TO RE-APPLY YOUR SUNSCREEN OR YOU ARE BACK TO ZERO PROTECTION
This is absolutely essential and given that we are often in and out of the pool it may mean slathering on the sunscreen multiple times a day.
4. A FAKE TAN WON’T PROTECT YOU FROM THE SUN
And neither does a real one for that matter. So even if you have olive or tanned skin make sure you continue to use sunscreen as the sun can still do unseen damage.
5. TEAM IT UP WITH OTHER PROTECTIVE FACTORS
There are other things you can be to protect yourself from the sun. In addition to wearing sunscreen, you can also seek shade and make sure to wear protection clothing including hat and sunglasses.
