FAQS

DO YOUR PRODUCTS CONTAIN EGGS?
Although we note that egg yolks are one of the best sources of Vitamin D, apart from actually spending time in the sun, none of our products contain eggs (no yolk, no white, no shell!). We just really enjoy an eggy pun.
What is broad spectrum?
A broad-spectrum sunscreen will protect you from both types of the sun's harmful ultraviolet rays; UVB rays (the ones that will cause redness and sunburn) and UVA rays (the ones that can cause more serious damage deep in the skin and may fuel skin cancers and age spots).
Sunscreens that are not broad spectrum only protect against UVB radiation. For chemical sunscreens to be Broad Spectrum they require a combination of UVA and UVB absorbers. For example, Aminobenzoates, Cinnamates, Salicylates are UVB absorbers, and Benzophenones, Anthranilates, Avobenzones are UVA absorbers. Don’t worry too much about the names just know that you are covered for both types of damaging UV rays with Yolk SPF.
What is the difference between physical and chemical sunscreen?
Physical sunscreens (often called Mineral) act as a screen to absorb, reflect and scatter UV radiation to protect the skin; whereas Chemical sunscreens absorb UV light based on their chemical structure, also known as UVR absorbers.
Both have their pros and cons, and both are highly effective at protecting your skin from the damaging effects of the sun.
Do you use Chemical Ingredients?
Our products utilise a combination of chemical UVA and UVB filters to provide the best possible protection.
There is a lot of ‘noise’ around the use of chemicals in sunscreens but remember sunscreen is classified as a drug so it is a heavily regulated product that needs to go through rigours testing before being approved by the TGA. This is unlike the majority of other cosmetic products (makeups, nail polishes, hair sprays, shampoos, cleansers, deodorants, perfumes, soaps, and body lotions) that go onto your skin everyday. So in reality many of the claims are not accurate. The best sunscreen is the one you’ll wear! Forget the haters.
Is Yolk Water Resistant?
Yes! Our products are 2 hour water resistant. You may see some sunscreens on the market that have 4 hour water resistance but the recommendation from the Cancer Council is to apply every 2 hours when in the sun and more often if swimming, towelling, or sweating. Regardless of whether the water resistance is more than 2 hours, definitely reapply every 2 hours. Again, for those at the back, EVERY 2 HOURS (or sooner).
What is SPF rating?
SPF or Sun Protection Factor, is a measure of how well a sunscreen protects you from the sun. SPF is measured on human skin in a laboratory. Scientists measure how long it takes for intense ultraviolet radiation (specifically UVB) to burn skin with the sunscreen liberally applied compared to bare skin. For example, if skin protected with a sunscreen takes 300 seconds to burn, but bare skin burns in 10 seconds, the sunscreen’s SPF is 30 (300 divided by 10). SPF30, 40 and 50 sunscreens give a ‘high’ level of protection, with SPF50 filtering 98% of UVB radiation before reaching the skin. The + (plus) sign associated with the SPF number means that the SPF rating is higher than the number. The + sign can only be used for sunscreen products with SPF 50. Products labelled SPF 50+ have an SPF of 60 or more and provide a ‘very high’ level of protection. SPF 50+ products filter 98.3% of UVB radiation.
It is important to remember that there are many other factors that will play a part in sunscreen protection including:
- Solar intensity (time of day or geographic location)
- Skin type
- Amount of sunscreen applied
- Frequency of reapplication
- External factors like toweling, sweating or swimming
Remember Sunscreen should only form part of a complete sun protection strategy. Slip, Slop, Slap.
Is your sunscreen reef safe?
In Australia, the term "reef safe" for sunscreens is not regulated, meaning there are no national standards that define or certify whether a sunscreen is truly safe for coral reefs and marine ecosystems. While some ingredients have been linked to coral bleaching and marine toxicity, Australian regulatory bodies require substantial evidence before making definitive claims. Additionally, variations in reef environments mean that what might be "reef safe" in one location might not be suitable in another.
At YOLK SPF, we’re committed to minimizing our environmental impact and are continuously following research and industry guidelines. We prioritize using the safest, most effective ingredients available and encourage sustainable practices to help protect our oceans.
What are active ingredients?
Active ingredients in sunscreens are the components responsible for protecting the skin from the harmful effects of ultraviolet (UV) radiation. They can be divided into two main categories based on their mechanism of action: chemical (organic) filters and physical (inorganic) filters.
Our sunscreens include the following ingredients: Homosalate 100mg/g, Octocrylene 100mh/g, Octyl salicylate 50mg/g, Butyl Methoxydibenzoylmethane 30mg/g. and contain Sodium Benzoate.
How are sunscreens regulated in Australia?
In Australia, sunscreens are regulated by the Therapeutic Goods Administration (TGA), which is a part of the Australian Government Department of Health. The TGA ensures that sunscreens are safe, effective, and of high quality.
But not all skin types are the same?
We knew this! Recently published research has confirmed the matter and provides sun exposure advice that explicitly recognises the differing needs of Australia’s diverse population.

Do your products contain Parabens?
No way, All our products are paraben free.
Are your products vegan & cruelty free?
Yes!
Where is the sunscreen made?
We are a local West Australian Company and all our products are formulated and made within Australia - which has one of the harshest solar intensities in the world.
Can I use your sunscreen on my baby?
It is generally recommended to avoid using sunscreen on infants younger than 6 months. Their skin is more sensitive and more likely to absorb the chemicals in sunscreen.
Can I use sunscreen when pregnant?
Using sunscreen during pregnancy is important to protect your skin from UV damage and reduce the risk of skin cancer.
Opt for mineral sunscreens with zinc oxide or titanium dioxide, and avoid sunscreens with chemical ingredients.
Yolk SPF currently only provides chemical sunscreens, but we are working around the clock to get a mineral sunscreen in our range soon!
Always consult with your healthcare provider if you have any concerns about specific sunscreen products or ingredients.
