What is the difference between a 30 and 30 SPF?

At SPF 30, your skin is protected from 97% of UVB rays. Higher SPF products provide marginal increased protection from 98-99% of UVB rays.

Know that in the winter, UVB (sunburn ray) is less than in summer. In summer, UVB intensity is much higher. At high altitudes UVB is also more intense. UVA is out intensely all year and the broad spectrum term relates to how well a product blocks UVA.

How many UV rays does a 30 SPF sunscreen block?

But in reality, when measuring one of the two types of UV rays, an SPF 15 sunscreen blocks 93% of UV-B rays, while an SPF 30 sunscreen blocks 97% of UV-B rays.

One of the ways to judge the effectiveness of a sunscreen or suntan lotion is by the sun protection factor (SPF) rating listed on its label. In theory, the higher the SPF rating that a sunscreen has, the more harmful ultraviolet (UV) rays of the sun are blocked.

A sunscreen with an SPF rating of 50 blocks 98% of UV-B rays. So, contrary to intuition, an SPF 30 sunscreen is not 50% more effective than an SPF 15 sunscreen, but only 4% more effective. And the jump from SPF 30 to SPF 50 gives you only an additional 1% greater protection from the sun.

So read the label to make sure that the sunscreen you buy protects against both types of UV. • Remember that sunscreen has a limited shelf life. That bottle of sunscreen left over from last summer may have lost a great deal of its effectiveness, especially in its ability to protect against UV-A rays.

Now that you know that it really isn’t worth spending more money for a sunscreen with an SPF rating higher than 50, here are a few tips to increase the effectiveness of the ones you do use:

Marketing. Companies such as Neutrogena, which provide a range of sunblockers with ratings as high as SPF 100 and SPF 110 – all considerably more expensive than SPF 50 sunscreens – are hoping that you don’t know the actual difference between the different SPF ratings, and will be lured into believing that an SPF 100 sunscreen really does offer 50% more protection than an SPF 50 sunscreen. At least one class action lawsuit is being considered against these manufacturers, charging them with intentionally deceiving their customers about the effectiveness of their sunscreens.

Is Walgreens recommendation based on data?

Recommendations are generally based on data from dozens, if not hundreds of studies that all show similar results,” Jamal Downer, Walgreens Pharmacist and their Sun Protection Expert from Walgreens ‘ Destination Healthy Skin pop up with the Skin Cancer Foundation, tells HelloGiggles.

Sunscreen is probably the worst part of your morning skincare routine — seriously, finding a sunscreen that’s not greasy, won’t make you break out, and doesn’t stink is akin to finding Gucci loafers on sale — but it’s also arguably the most important.

So in this locale, higher SPF can make a big difference in protecting the skin. ”.

But in a major plot twist, this new study concluded that SPF 100+ was significantly more effective than SPF 50 (and, therefore, SPFs less than 50) at preventing sunburn.
