WHAT DOES SPF MEAN? | A NOTE ON SUNSCREEN

Some of us have never given the little letters "SPF" a second thought and have just figured, "I've got sunscreen on, I'm protected." when this may not precisely be the case...

SPF stands for Sun Protection Factor and is always followed by a set of numbers, (15+/25+/30+/50+) this is all meant to be informative information, but what good is it if you don't really understand what it means? Obviously the greater the number, the more protection, but, why is it that some need more protection than others and how does this work?

How much SPF is enough 15+ / 30+ / 50+?

How the number works depends on your skin - people with naturally darker pigment in their skin who use an SPF15+ will be protected for longer than those with fairer skin using the same SPF15+ sunscreen. The Sun Protection Factor (15+) advises that your skin will be protected 15 times longer than you would had you not been wearing any sunscreen at all. 

So the question of how long you will be protected for comes back to you and the real question is: how long does it take before you start wearing the effects of a little sun on your skin?

Let's take the example of someone with fair skin who may start reflecting the signs of sun exposure after only 5 minutes, if this person wears an SPF of 15+, what this means is that they are now protected for 5 minutes x 15 times longer (5 x 15 = 75 minutes) - 1 hour and 15 minutes in the sun.

Equally, if you are naturally protected by darker pigment in your skin and perhaps only start to see sun exposure signs after 30 minutes, you will be protected for 30 minutes x 15 (30 x 15 = 7.5 hours).

Have you checked where your sunscreen was made?

The Australian sun has the highest rate of UV radiation in the world. This means that it is important that we buy sunscreen that has been made with the Australian sun in mind.

If you have some wonderful sunscreen you picked up on your European travels - the chances are it is not going to be as effective in the Australian sun. A European sunscreen boasting an SPF30 may in fact act like an SPF15.

As it is important to make sure you are protected from the sun, it is also important that you know how long you're protected for and that your sunscreen is sufficient.

What other steps can we take in our skincare to protect ourselves from sun damage?

in order to provide our skin with that added protection from the skin pre and post sun-exposure, we need to seek out skincare high in antioxidants.

UV radiation (from the sun), pollution and smoking, in addition to internal factors including normal cellular metabolism, can generate molecules known as free radicals which are damaging to the skin.

Antioxidants combat these free radicals which can reduce inflammation, protect the skin against these harmful factors and potentially help ward off skin cancers. In turn, antioxidants have been known to slow the signs of ageing through skin cell protection.

It is suggested by studies that combinations of antioxidants are more effective than single formulations. This is why in each Aurae Skin product, we super-boost our antioxidant formulation with a variety of antioxidants including:

  • Vitamin C
  • Vitamin E
  • CoEnzyme Q10 (Ubiquinone)
  • Kakadu Plum Extract

These are just a few examples of the antioxidants included in our products. The antioxidants we've curated are known to be the most powerful and potent in the skincare world and therefore seek to provide your skin with the added protection it needs pre and post sun exposure.

When seeking to protect your skin, always apply our Beauty Boost Hyaluronic Serum prior to moisturiser and sunscreen to add more antioxidant protection.

When seeking to recover, revitalise and repair, our Wonder Glow Revitalising Repair Oil is the perfect sleeping companion to boost repair overnight.

Don't forget to always add antioxidants into your skincare routine to benefit healthy, protects skin.
