Five minutes with: Antonia Kidman

What attracted you to Living Nature?

I was attracted to how natural and pure the products are. They have no preservatives, additives or parabens, which is very important to me.

In addition to your skincare, do you live as naturally as possible?

I try to abide by nature as much as I can. I don’t eat 
100 per cent organically but I do eat healthily and I avoid preservatives and processed foods. I never buy them for my children. I have a compost bin, I grow my own vegetables and I have citrus trees.

What is your philosophy for day-to-day living?

You can choose your mood. You can’t choose what people do to you but you can certainly choose how you react. You are in control of your own mind. That said, I’m very aware that there are ups and downs in life. For me, lifting myself up if I feel a little flat is about engaging with other people and getting out and doing exercise.

How do you juggle work, exercise, motherhood and looking good?

I’m very busy but my life is fairly structured – I like routine! Exercise is a big part of my life. I go to the gym, run, swim and do yoga. As for looking good, I think that keeping fit and eating well definitely shine through.

Everything you need to know about sun protection

How does sunscreen actually work?

Sunscreen protects us from UV rays. When it’s on your skin, it can either absorb the energy from the UV rays so your skin does not, reflect the UV rays away, or do a combination of both.

What does the SPF factor actually mean?

The SPF factor is a short way of informing consumers of the multiple of time that a person may be prevented from sunburn. It compares how many multiples of minutes you are prevented from sunburn for your given type of skin.

For example, if you are fair and usually see the very first signs of sunburn (reddening) in 10 minutes, then a factor 30 sunscreen means that you are protected for 30 times as long to see the same first signs of sunburn, ie. 300 minutes.

It is important to remember however, the factor represents an idealised calculation and should only always be used as a guide. In reality, there are many variables which alter this equation such as your particular skin type, time of day, time of year, how well your sunscreen is applied, quality of sunscreen, amount used, etc.

What’s the difference between UVA and UVB rays?

UVA rays, with their relatively longer wavelength, penetrate deeper into the skin, into the dermal layer. Its damage tends to be seen later on, such as prematurely aged skin and wrinkles.

UVB rays, have a shorter wavelength and higher energy. They don’t penetrate as deeply and its damage is seen immediately on the epidermal layer of the skin, such as the redness of sunburn.

What’s the difference between physical and chemical sunscreen?

So-called “physical” sunscreens are those where the sunscreen agent almost exclusively reflects the damaging UV rays. These tend to be made from minerals such as titanium dioxide or zinc oxide.

The so-called “chemical” sunscreens are those where the sunscreen agents absorb the energy of the UV rays. If you like, think of the aluminium foil under your kitchen grill as the physical sunscreen and a piece of bread sitting upon the foil under as your chemical filter.

The aluminium foil reflects the heat, whereas the piece of bread absorbs the heat (and hence turns brown).

If I put on sunscreen at the beach and then go straight in the water, do I need to top-up when I get out?

You should always reapply sunscreens after going into the water.

If you plan to be in the water, then look out for “water resistant” sunscreens and the extent of water resistance protection provided. These formulations have been designed to be “film-forming” which means it is less likely to wash off in the water.

And what if I never go into the water – does that mean I’m protected all day at the beach?

No. It is always a good idea to reapply frequently. If you remember, there are sunscreens that reflect UV, and those which absorb UV – and in reality, most products on the market use a combination of both to achieve the best possible protection.

So where there are sunscreens that absorb UV, these are intended to deteriorate as they absorb the UV, so reapplication is necessary.

Think back to that piece of bread under your kitchen grill, as it turns brown and black by absorbing the radiant heat, it will need to be replaced.

Is there such a thing as laying on the beach safely?

Unfortunately no. Furthermore, there are particular times – such as between 10am and 2pm in the middle of summer – when laying on the beach without sun protection will definitely cause you harm. The “slip, slop, slap” campaign exists for a reason.

If you use an SPF 30 moisturiser and an SPF 15 foundation – does that mean you have a protection of SPF 45?

No. This is a common myth. The factors are non-cumulative and there are many variables. Remember that the SPF is a guide and is affected by many things. Continue to use high SPF skin products for best protection from damaging UV rays.

Am I still protected in the afternoon if I put on sunscreen in the morning?

Again, there are many variables to consider – how much was applied in the first place, how much was rubbed off, how much exposure have you had in the morning. Generally, if you have the opportunity, you should try and reapply.

Should I put my daily facial sunscreen under or over my moisturiser?

The UV rays from the sun are not too fussy – having travelled all the way from the sun to your skin, it does not matter too much whether it is absorbed or reflected before or after your moisturiser.

Use a pattern you feel most comfortable with. NIVEA SUN Light Feel Daily Face Veil SPF30 is so light that it may be better under your moisturiser should you need it.

For people who burned easily as a kid – does that mean they will have more wrinkles later in life?

Regretfully, the UV damage you may have had as a kid may stay with you later in life. However, all the steps you take now to minimise further damage, no matter how small, will be beneficial as you get older.

There are also now several products on the market – such as NIVEA’s DNAge range – which can help minimise past damage and protect you from future damage.

Do you still get the benefits of Vitamin D if you’re wearing sunscreen?

Yes. Most Australians will receive enough of the sun in their everyday activities to generate sufficient levels of Vitamin D without deliberately exposing themselves to the sun.

Even in the middle of winter in Australia, sun exposure on your face, arms and hands for two to three hours a week is more than sufficient for your body to make its own Vitamin D.

Also, Vitamin D is stored in fat and muscle and your body can rely on these tissue stores for between 30 and 60 days.

Should I still wear sunscreen on a cloudy day?

Yes. Cloud cover is not a good indication of protection against UV. Whilst some rays may be reflected by cloud, enough do penetrate cloud cover and these are still damaging on your skin.

Can I get sunburnt in my car?

Yes. Whilst you may protect your eyes with sunglasses, your skin is still exposed to UV rays, which like light, are reflected off many other surfaces. The indirect exposure (say from the road) reflects damaging UV rays which can sufficiently cause damage and sunburn.

Why should we bother with sunscreens?

Skin cancer is the most common cancer affecting Australians and New Zealanders.

Australians suffer from one of the highest rates of skin cancers in the world. Sun exposure is the cause of nearly all non-melanoma skin cancers and about 95 per cent of melanoma in Australia.

It is therefore important to protect yourself from the sun, to reduce your chance of getting skin cancer.

Melanoma cancer is amongst the most commonly diagnosed cancers, especially in the younger population. For non-melanoma skin cancer, based on the most recent survey in 2002, there are projected to be around 433,000 new cases in 2008, of which 295,000 will be basal cell carcinoma and 138,000 squamous cell carcinoma. The statistics speak for themselves.
