How does SPF rating work?
A higher SPF rating requires a lot more sunscreen chemicals for diminishing returns. SPF 15 blocks 94% of UV radiation while SPF 30 blocks 97%, a 3% difference but a lot more ingredients that make higher SPF products feel thicker on the skin. SPF 30 provides protection for 8 hours of sun. The amount of protection, in reality, depends upon both the SPF rating and the thickness or amount which is applied.
(The other way to look at this is that SPF 15 allows 6% of UV through, while SPF 30 allows 3%, so a reduction of 50%. It depends on how you do the math.)
How does sun protection work?
There are two main types of sunscreens. Firstly, natural sunscreens that use Zinc Oxide or Titanium Dioxide as a physical barrier that reflect UVA and UVB away. The second type is "UV Filters" that absorb high energy UV radiation and emit low energy radiation. These are always synthetic, which is why we choose to use Zinc Oxide to provide natural sun protection.
Isn’t Zinc normally white?
Yes, Zinc Oxide would normally be white on the skin. We use a special type of Zinc Oxide that is made here in Australia that is dispersed within Jojoba Oil which helps make it clear and non-greasy. The Iron Oxide in our formula gives the cream its tint and also helps it blend in nicely to the skin. It’s also responsible for the colour in Australia’s red, fertile soils.
What are UV filters?
These are various chemicals that absorb high energy UV radiation and re-emit it as low radiation. These are always synthetic, which is why we choose to use Zinc Oxide to provide natural sun protection.
Should I wear sunscreen every day?
This is a very personal choice and depends on a lot of things such as how much time you’ll be spending outdoors in direct sunlight as well as your skin tone and tolerance of the sun. Personally, we use sunscreen when we know we are going to be spending a lot of time outside, but on other days when we are just going into the office, we prefer to use one of our other non-SPF moisturisers, and we have a few. Bear in mind that up to 2/3 of Australians are Vitamin D deficient. Only around 15 minutes of sunshine is required 2-3 times a week for the average person to obtain correct amounts of Vitamin D.
Where can I find out more about sunscreen?
Sunscreens with SPF ratings over 15 are considered "therapeutic products" and so their safety or efficacy cannot be questioned. The way to get information is to spend 15 minutes doing your own research online to help choose the right sunscreen for you. Wikipedia, although not always accurate, has a very good page on sunscreen and well worth getting the facts. Try and read at least from half way down the page if you can.
Do your SPF products contain nano particles?
Our sunscreens do contain nano-particles. Any clear Zinc on the market is now classed as ‘nano-particles’ BUT of different sizes. These have previously had a bad rap, however, the description of a nano-particle has since changed so they will not cause any harm. We use a standard Zinc Oxide with a median particle size of approximately .31 microns (this is 310 nanometres), with all particles between 0.25 microns and 0.35 microns. As a result, Zinc Oxide is nearly invisible when applied to the skin yet still offers both broad-spectrum UVA and UVB protection. This means none is absorbed into the bloodstream.
Is your Natural Sunscreen SPF 30 water-resistant?
This formula is water-resistant but make sure to reapply immediately after activity and swimming. Pair up with our SPF 15 Lip Balm to ensure you are fully covered and protected.
What is the percentage of Zinc Oxide in your sunscreens?
Our SPF 30 products contains 24.96% Zinc, and our SPF 15 products contains 19% Zinc.
Why can I only find SPF 30 and not the SPF 40?
Our Natural Sunscreen SPF 40 is only available in Australia. Our Natural Sunscreen SPF 30 is available everywhere else. Both offer the same level of protection, but just have different SPF ratings due to different regulatory and labelling requirements.
Can I use MooGoo on a newborn?
We get this question a lot. But the answer is YES! All of our products are suitable for newborns but we suggest you always patch test first to check for allergies to any natural ingredients.
What SPF testing have your products gone through?
For those that asked, here is the SPF testing performed for this product, as well as Broad Spectrum testing. We also did a voluntary follow-up test on a 18 month old batch, and preliminary waterproof testing – while we the test results are 40 mins waterproof, we recommend always reapplying any sunscreen after swimming as the mechanical action of swimming and drying can remove sunscreen.
My sunscreen seems to be separating. Does this mean it's old and no longer effective?
Making a sunscreen with Zinc can be a tricky process. Zinc can be quite thick so it needs a lot of emulsifiers so it can be rubbed onto the skin easily. Sometimes if our Zinc sunscreen is stored in a hot place, such as in direct sunlight on the beach or in a hot car for long periods of time, it can cause the formula to start separating. You may see a clear liquid come out of the tube. If this happens, we recommend giving the bottle a hardy shake to get things mixed together again, or it can be rubbed together again directly on the skin. The effectiveness of the sunscreen is not affected (we’ve done some tests to ensure of this), but as per the directions for use on the back of the packaging, we recommend that it be stored below 30°C.
