What is sunscreen? 

Sunscreen provides broad-spectrum protection against the sun's harmful ultraviolet radiation (UVR). It does not prevent the formation of pearly or brown-grey-colored cells in the upper layer of the skin known as the epidermis. Thus, sunscreen can prevent the skin from the effects of UVR, but not the formation of any new lesions.

Sunscreen should be applied at least 30 minutes before going outside to prevent exposure to UVR.



What types of sunscreen are available?

There are many brands and products available, but the two most common UV-protective and non-comedogenic are zinc oxide (ZnO) and titanium dioxide (TiO2).

However, we see on Instagram that ZnO is fading faster than in previous years.

Does the SPF level really matter?

Yes, it does. SPF is necessary to block harmful UV rays.

Three lines: the UVB factor (the amount of UVB rays that a sunscreen blocks) or the zinc factor (the amount of zinc oxide that a sunscreen blocks)

or the zinc factor (the amount of zinc oxide that a sunscreen blocks) the reference level. Your level will be less, higher, or equal to this level.

Your skin gets more sunscreen exposure than you

go outside. You are in contact with the sun for less than 8 hours a day (including the 20 minutes spent at the pool).

The Institute of Medicine recommends no more than 1 ounce a day. A shot glass would be equal to .8 oz.

You should keep your sunscreen on all day long.

When Should I Use a Sunscreen?

the most effective way to prevent sun damage is to avoid the sun entirely during the peak hours of the day. That means setting your alarm clock when you are in school or work so you can get outside for the recommended two hours of sunlight during the middle of the day (approximately 10 am to 3 pm). To be safe, wear sunscreen at all other times, even when you are indoors.


Help protect your Eyes

The sun's rays from your face can damage your eyelids. Eye sunscreen should be used with your sunglasses to prevent UV light from hitting your eyes and causing damage to the optic nerve, causing vision damage, or even blindness. The number one choice of sunglasses when you're on holiday is sunnies with UV filters - this stops the sun from harming your eyes.


It looks like skin cancer is indeed an important topic that merits serious discussion. Please feel free to make further comments and to ask further questions and thanks for your interest!
