FAQ
Frequently Asked Questions

Did you know that Humans get 90% of our vitamin D from the sun, that’s why vitamin D is called the “sunshine vitamin”?

Your body is designed to get the vitamin D it needs by producing it when your bare skin is exposed to ultraviolet B (UVB) sunlight. This is the most natural way to get vitamin D.

When the sun is low in the sky (e.g, Outside of summer or before 10 am or after 3pm during summer), your skin doesn’t produce much vitamin D. This is because UVB rays (which are relatively weak compared to UVA rays) are restricted or even blocked entirely by having to travel a longer distance through the atmosphere, so even less of these vital rays contact the skin at these times

A good rule of thumb is if your shadow is longer than you are tall, you’re not making much vitamin D.

You should also be aware that whilst you can get sunburned through windows whilst in your home, office or even car, this is caused by the UVA rays. UVB rays don’t pass through glass, so whilst you may think you are getting a dose of sunlight and building your vitamin D this isn’t the case at all.

What does the SPF value on sunscreen mean?

SPF or Sun Protection Factor indicates the UVB/sunburn protection provided by sunscreen. The SPF value indicates the level of sunburn protection provided by the sunscreen product. All sunscreens must be tested according to an SPF test procedure under the guidelines of the TGA. The test measures the amount of ultraviolet(UV) radiation exposure it takes to cause sunburn when a person is using a sunscreen in comparison to how much UV exposure it takes to cause sunburn when they do not use a sunscreen.

An SPF 50 theoretically allows 50 times longer exposure than no sunscreen at all and an SPF 30 allows 30 times longer. Despite this we at Solar D recommend that you regularly reapply sunscreen at least every 2 to 4 hours, depending on the weather conditions and if you’ve been swimming or exercising. It’s always better to be safe than sorry and suffering the consequences of being sunburned.

What does "broad-spectrum"mean on sunscreens?

The broad-spectrum test measures a product’s ultraviolet A(UVA) protection relative to its ultraviolet B (UVB) protection. Sunscreens that pass this test may be labeled as “Broad-Spectrum SPF (value)” on the front of their label. For broad-spectrum sunscreens, SPF values also indicate the amount of overall protection. Broad-Spectrum SPF products with SPF valued higher than 30 provide greater protection and may claim additional uses. Only broad-spectrum sunscreens with an SPF value of 30 or higher can claim to reduce the risk of skin cancer and early skin aging if used as directed with other sun protection measures.

Does Solar D Sunscreen help prevent skin cancer?

Yes. All Solar D sunscreens are classified as Broad-Spectrum. According to the TGA, when used regularly and with other sun protection measures, Broad-Spectrum sunscreens with SPF 30 or higher decrease the risk of skin cancer and early skin aging.

What lifestyles contribute to Vitamin D deficiency?

Due to our modern lifestyles and education, we now produce far less vitamin D from sun exposure than decades ago. We are spending our days indoors, at school, at work, and in cars where sun exposure is reduced dramatically. These lifestyle changes have caused vitamin D deficiency rates to rise and the prevalence of vitamin D deficiency varies among the Australian population, with the groups at greatest risk being those with limited sun exposure.

When does Solar D Sunscreen expire?

Our sunscreens all have a shelf life of 3 years. Our products have an expiration stamped on the either the top or bottom of the product.

Always read the label, use only as directed
