The Difference Between SPF 30 And SPF 50
At KINeSYS one of our missions is to empower people with the knowledge to stay protected from the sun. So let's unpack the cryptic world of SPF. What does it stand for? Do the numbers really matter? How does SPF relate to the different types of sun rays? The KINeSYS team is here to uncover the facts, and help you to understand what they mean for you.
Sun Protection Factor
UVB rays are the ones that cause sunburn when you have been indulging in a little too much time outdoors, without adequate protection. SPF stands for ‘sun protection factor’ and indicates the level of protection a product offers from the sun’s harmful UVB rays.
When we look at the difference between SPF levels, SPF 30 and SPF 50 for example, this comes down to the percentage of the sun’s UVB rays that the product can block. A product with an SPF level of 15 will block around 93% of the sun’s UVB rays. You will often find SPF 15 in makeup and skin care products. However, in sunscreens, the industry standard, and the SPF recommended by Dermatologists is generally SPF 30 and above.
A sunscreen with SPF 30 will protect you from around 96.7% of UVB rays, whereas an SPF of 50 means protection from about 98% of UVB rays. Anything beyond SPF 50 makes very little difference in terms of risk of sun damage, and no sunscreens offer 100% protection from UVB rays.
But what about UVA rays?
Of course UVB aren’t the only rays you need to worry about. UVA rays cause wrinkling, premature ageing and skin damage. Whilst the SPF level of your sunscreen determines the level of protection you’ll receive from UVB rays, UVA protection is indicated by the term ‘broad spectrum’.
Protecting your skin from both UVA and UVB rays is important for skin safety and for preventing damage and premature aging. Choosing a sunscreen that has a SPF of at least 30 and is broad spectrum will help ensure adequate protection. So you can get active, go adventure, or simply be lazily immersed in nature, without worrying about the harmful effects of sun exposure.
What’s the best sunscreen for you?
At the end of the day, the best sunscreen is the one you love to wear.
