What we need to know about SPF

Mon, 13 Jul 2015

As you already know, it is highly important that we protect our skin against UVA and UVB rays, responsible for premature skin ageing and skin cancer. Although sunscreens are easy to find and use, we need to have the necessary information to provide our skin with sufficient protection.

 

What is SPF?

The acronym ‘SPF’ stands for Sun Protection Factor and is used to measure the longevity of protection provided by the sunblock. Therefore, an SPF 50 will provide you with longer protection, because it should need to be reapplied less frequently than a SPF 30 or 15. It also blocks a higher percentage of UVB rays from the sun, meaning you are less likely to burn or experience skin damage.

Many people fail to reapply their sunblock as frequently as they should and don’t bear in mind that the lower the SPF, the less coverage they are getting. Although sunblocks used to be cakey and sticky, there are many on the market now which are matte, lightweight and effective.

 

What is the difference between a moisturiser with SPF and sunscreen?

A lot of moisturisers, BB creams, CC creams and foundations contain SPF; although it helps against sun damage, they are not substitutes if you're looking for serious sun protection.

Remember to apply sunscreen daily, reapply every 40 to 80 minutes when sweating or swimming, or after every few consecutive hours of direct daylight exposure.  Don’t forget your earlobes, neck and the top of your hands and your feet.  You will keep your skin young and reduce your risk of brown spots, sagging, and, most important, skin cancer!
