We’ve got great news here at MANDA: we’ve received an official SPF 50 rating!
You may be wondering what an SPF rating really means and how the ratings compare to each other. You’re not alone. With thousands of sun care products on the market, all containing different ingredients and different levels of SPF, choosing the right one can spark up some confusion.
To determine a sunscreen’s SPF, testers round up 20 sun-sensitive people and measure the amount of UVA/UVB rays it takes for them to burn without wearing any sunscreen. This test is then repeated with the sunscreen in question applied. Finally, the “with sunscreen” number is divided by the “without sunscreen” number, and the result is rounded down to the nearest five. This number is the sunscreen’s SPF.
To be clear, the SPF number rating doesn’t refer to how long you can spend in the sun without getting burned. It actually refers to the amount of UVB protection the product offers. For example, sunscreen with SPF 15 blocks 93% of UVB rays, SPF 30 blocks 97% and SPF 50 blocks 98%. So although SPF number ratings multiply rapidly, the actual percentage of added protection is fractional. In 2011, the FDA deemed SPF50 the highest possible rating.
It’s also important to realize that the kind of sunscreen you put on your skin and how you apply it makes a huge difference. A sun paste like MANDA that literally rests on your skin contains ingredients that act as a physical shield against UVA/UVB rays. However, chemical sunscreens that seep into your skin absorb the UVA/UVB rays and render them inert. They also offer no visual indication as to where you are protected and wash off easily so it’s necessary to reapply frequently to protect against skin damage.
MANDA Organic Sun Paste is not only a physical sunscreen that blocks harmful rays but also contains ingredients with natural occurring sun protection properties. With zinc and thanaka, MANDA functions as a protective shield to block UVA/UVB rays while fostering your skin’s optimum wellness.
