Sunscreen - General

What exactly is the SPF rating on sunscreen and what does Broad Spectrum mean?

SPF stands for Sun Protection Factor.

Everyone has a natural ability to protect themselves form the sun's harmful UV rays. People with darker skin can protect themselves for longer intervals than those with fair skin. The SPF rating gives you a multiple of your skin's natural protection.

The SPF rating however focuses solely on UVB rays. These rays are responsible for sunburn and the main contributor to melanoma.

The SPF rating does not indicate the level of protection you get from UVA rays that are present in much higher levels in sunlight than UVB. They are the main cause of skin aging and also plays a role in causing some skin cancers.

Sunscreen with a Broad Spectrum rating protect against both UVA & UVB.

What's the difference between SPF 30, SPF 50 and SPF 100?

You might be surprised to learn that the difference is minimal. SPF30 blocks out 97% of UVB radiation, while SPF50 blocks 98% and an SPF100 99%.

Often sensitivity to the chemicals needed to get that fraction more protection, outweigh the benefits, particularly for people with sensitive skin.

The best protection comes from using a broad spectrum SPF30+, applying it properly and reapplying every 2 hours.

How do I apply sunscreen correctly?

Sunscreen should be applied 20 minutes before going outdoors. For an adult, recommended sunscreen application is 5mL (approximately one teaspoon) for each arm, leg, body front, body back and face (including neck and ears). That equates to a total of 35mL (approximately seven teaspoons) for a full body application. It needs to be reapplied at least every two hours, irrespective of the water resistance of the sunscreen, and should be reapplied after swimming, sport, sweating and towel drying.

Lastly, remember that sunscreen should always be used in combination with other sun protection measures, including wearing sun protective hats, protective clothing, sunglasses, and seeking shade.

Are your sunscreens reef-friendly?

Absolutely! Our SPF products are proudly reef-friendly as we don't use synthetic ingredients that are known to damage and harm coral reefs.

Do your sunscreens contain nano-particles?

Our zinc is non-nano and has been independently tested by the CSIRO using laser particle diffraction. The zinc oxide used in Wotnot sunscreen is micron sized i.e. >1000nm (nanometers). Nano particles are defined as particles in a size ranging from 1-100nm. Wotnot zinc particles are 10-1000 times bigger than a nanoparticle and so are not expected to cross the barrier of the epidermis. The zinc oxide we use is specifically made for Wotnot 

Why does my sunscreen appear separated and the oil has come out the top? What should I do and is it still effective protection?

Our sunscreen is rich in nourishing oils and being a natural product the ingredients may separate. It is best to massage and then shake the tube well before use. 

Is your sunscreen water resistant?

Wotnot natural sunscreen 100g and 150g contain beeswax which helps create a natural resistance to water but has not been tested for water resistance. We recommend that you use a water resistant product in the water and regardless of which sunscreen you use you should always reapply after being in the water or towelling dry. Our Face sunscreen is water-resistant for up to 2 hours. 

What is the difference between your SPF30 sunscreen and a SPF 50 sunscreen?

Our sunscreen is TGA listed, has been independently assessed and tested to TGA requirements and awarded an SPF of 30+. While SPF 50 sounds like a significantly higher level of protection than an SPF30 the difference is not really in the amount of UV protection. An SPF 50 sunscreen will filter 98% of UV radiation while an SPF30 product filters 96.7% so the difference is not large. 

How these SPFs differ is around the length of time that each will protect you, but even this is not as simple as it seems. Everyone’s skin is different and each person’s skin can be exposed to the sun for different lengths of time before burning. 

Sunscreens extend the time before burning by a multiple of the SPF. Eg if you have fair skin and would normally burn in 10 minutes without any sun protection then an SPF 30 will give you 30 x 10 minutes protection while an SPF 50 will give you 50 x 10 minutes. The issue is that all sunscreens will rub off over time with normal activity and perspiration and so in some cases the higher SPF can give a false sense of security. Due to normal activity all sunscreens need to be reapplied regularly. 

Is Wotnot sunscreen non-comedegenic (ie doesn’t clog pores?)

While we have not carried out any comedogenic testing on our sunscreen, our formula uses all natural ingredients and does not contain any of the ingredients flagged as comedogenic (see http://www.acne.org/comedogenic-list.html )

How do I best clean my face after using your face sunscreen?

Wotnot sunscreen is a physical (zinc based) sunscreen and the base consists of oil so you can’t just wash off easily.

Good news is that you don’t need a special sunscreen cleanser. Zinc sunscreen is easy to remove with an oil cleanser.

Pick an oil. You can use coconut oil, sweet almond oil, jojoba oil, even olive oil works. Pour a little into the palm of your hand, then massage it all over your face. Leave it to soak in for a minute or two.

Run a face washer under some warm water, but not too hot. Wring it out, hold it over your face for around 10 seconds, and then gently wipe away the oil and the sunscreen.

Repeat if you need until all the sunscreen is gone. This will do wonders for your skin as well as gently remove the sunscreen.

We also have Face Wipes available for 2 different skin types that are infused with certified organic oils that will work a treat too. Great news is that our face wipes are certified compostable so you can just pop them in your compost bin when you’re done 

How come your sunscreens do not make my skin go white? 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 and dispersed within jojoba oil which helps make it clear. 

What makes your face sunscreen special?

Our face sunscreen is firstly designed to provide high level broad spectrum protection. But we didn't stop there! After collaborating with our tribe we also added Cosmos approved plant collagen proven to help improve the appearance of fine lines and wrinkles by up to 16% when used daily over 8 weeks. And lastly our beautiful natural oils and extracts work to leave skin glowing ready to face the day or perfectly primed before applying makeup. 

How ofter do you recommend reapplying sunscreen?

Sunscreen naturally wears off and regardless of the level of protection should be reapplied regularly, after swimming, towelling dry or prespiring.

What is the preservative that you use in the face sunscreen?

The preservatives in our face sunscreen are caprylyl glycol and octanohydroxamic acid. We take great care in chosing our ingredients and will always choose the most gentle and effective options available. 

What age can your baby and family sunscreen be used from?

Wotnot natural sunscreen is suitable for babies from 3 months of age. Babies under 3 months should avoid direct sun exposure. As with any product, if you feel that you or your baby may be allergy-prone then we recommend that you do a patch test before general use. Please ensure to read the ingredients and directions for use carefully: https://wotnot.com.au/products/30-spf-baby-sunscreen-100g
