Sunscreen ingredient revealed as necessary for best skin protection

It’s long been known that using a broad spectrum high SPF sunscreen, one that protects against UVA and UVB rays, is essential – no matter what the time of year.

But according to DeAnn Lazovich, an associate professor of epidemiology at the University of Minnesota, sunscreen has its limits, and not all are created equal.

Professor Lazovich recently took a look at sunscreens, revealing the one ingredient a good formulation should include.

‘A product has to say it’s “broad spectrum” to provide UVA protection. Also look for zinc oxide, which provides stronger UVA protection than other ingredients do,’ she told Prevention.

As it turns out, some sunscreen formulations lack zinc oxide – a mineral that starts protecting your skin as soon as you put it on. 

The mineral sits on top of the skin and forms a protective barrier against the sun’s harmful rays. 

Zinc oxide has also been shown to lessen skin damage and sun-related premature ageing, said US-based dermatologist Cybele Fishman for InStyle.

If you are looking for a product that offers greater coverage, look for one that protects against both UVA and UVB rays and contains the physical blocker zinc oxide.

Helpfully, the Annual Sunscreen Guide by the Consumer Report has sorted the effective products from those doing little more that moisturising your skin.

After testing 70 products, one came out wholly on top, with a 100 per cent score for the fourth year in a row.

La Roche-Posay’s Anthelios SPF 50 Comfort Cream, which retails at $23.99 at Priceline, gained first place in Consumer Report’s list.

After testing some 70 sunscreens for both UVA and UVB ray protection, the experts found that the product by French dermatologists is the best that money can buy.

This is partly because it contains zinc oxide, the proven ingredient with sun protection.

Top tips for using sun cream 

* Put it on clean, dry skin 15 to 30 minutes before you go out in the sun to allow it time to interact with your skin. Re-apply it just before you go out – you’ll increase the amount applied and be more likely to get the stated SPF benefit.

* Cover all parts of the body not protected by clothing (don’t forget your ears, the back of your neck, the backs of your hands and the tops of your feet).

* Apply it evenly, and don’t rub it in excessively – most sunscreens will absorb into the outer layer of skin and don’t need to be rubbed in vigorously.

* Re-apply at least once every two hours and after swimming or exercise.

* Think beyond the beach and pool – use sunscreen whenever you go outdoors for a significant amount of time, such as to the park, a lunchtime walk to the shops, playing sports or gardening.

* Store your sunscreen at a temperature of less than 30 degrees Celsius. If you leave it in the glovebox of your car or in the sun, it may lose its effectiveness. Keep it in the esky with the drinks, in the shade or wrapped in a towel.

* Don’t use sunscreens that have passed their expiry date as they may have lost their effectiveness.

How much sun cream should you really use? 

* One teaspoon for head and neck

* Two teaspoons for the torso

* One teaspoon for each arm

* One teaspoon  for each leg

The sunscreen also contains the antioxidant, Baicalin, to fight free radicals on the surface of the skin whilst offering the highest UVA and UVB sun protection.

In their research, Consumer Report also found that plenty of products aren’t necessarily doing their job.  

‘Of the 73 lotions, sprays, sticks and lip balms in our ratings this year, 24 tested at less than half their labelled SPF number,’ researchers wrote. 

‘That doesn’t mean the products aren’t protective at all, but you may not be getting the degree of protection you think you are.’  

 Their bottom line was that it always pays to check a sunscreen’s rating.
