Looking at the SPF rating system for sunscreen can be quite confusing if you don’t know what everything means. For instance, you’ve got 30 SPF sunscreen for face, as well as SPF 15s, SPF 50s and even SPF 100s manufactured by certain brands. So, what’s it all about?
Logically speaking, you’d assume that a sunscreen with an SPF of 15 would offer half the protection of an SPF 30. It would be easy if that were the case, but the reality is different. It simply doesn’t work that way.
How The SPF System Actually Works
Ok, so it breaks down like this. Most brands will offer a range of SPF-rated products that range from SPF15 to SPF50. There are some that go as low as SPF2 or as high as SPF100, but the numbers used are not used in a particularly logical way.
How it actually works is like this…
- SPF 15 offers 93% protection against the sun’s UV rays
- SPF 30 offers 97% protection against the sun’s UV rays
- SPF 50 offers 99% protection against the sun’s UV rays
In reality, there’s only a 4% difference between SPF 15 and SPF 30 – so it’s a long way from being twice as effective at blocking sun damage. Something else you have to factor into the equation is broad spectrum coverage, as that also affects the protection you get.
Broad Spectrum Coverage is Essential
Something you need to consider when buying 30 SPF sunscreen for face or any other SPF-rated sunscreen is whether or not it offers broad spectrum protection against the sun.
What this description means when present on the packaging is that the product inside protects you against both UVA and UVB rays. If your sunscreen doesn’t have this feature, then you’re open to being damaged by the sun every time you go out.
UVB rays are the type we all know about in that they’re present when the sun is out. That warmth you feel on your skin in the sun is UVB rays doing their thing. UVA rays are able to penetrate clouds, so they get you when it’s overcast and even when it’s raining! The very fact that it’s daylight outside means that UVA rays are present, so you need protecting from them. If you don’t, you risk skin ageing, wrinkles, dark spot and more.
Whichever way you look at it, regardless of whether you buy 30 SPF sunscreen for face or an SPF50 product, you’re going to have problems if you don’t have broad spectrum protection.
Choosing the Right Sunscreen For Your Needs
So, no a 30 SPF sunscreen for face will not protect you twice as well as an SPF 30 product. Sadly, it’s one of those misconceptions in circulation that actually results in harm to people.
Your main takeaway from reading our blog is that you should understand the rating system before you purchase your sunscreen. We’ve only touched upon the subject here, so go and do some research to ensure you’re able to make an informed decision.
The health of your and your family’s skin is at stake here, so it’s well worth the effort of furnishing yourself with what you need to know.
