About Sunscreens

Sunscreens are filters of UV energy. They are used to filter a PROPORTION ONLY of UV rays.

By definition, all types of sunscreen will include active ingredients which either absorb or scatter and reflect UV energy which would otherwise enter the skin and cause severe damage. UVNatural uses Zinc Oxide which is a reflector of both UVA and UVB Rays.

Myth: If you wear sunscreen you are fully protected from UV absorption and the suns harmful rays UVA and UVB and will not burn.

Not true!! Sunscreens are a means to REDUCE ONLY a dose of sunburn you will get if you don’t wear it. Hence, as sunscreen is used to delay this burning affect and to filter the penetration of Ultra Violet activity.

Fair Skin that burns without sunscreen in 4mins

Apply 30+ sunscreen 15-30 minutes before sun exposure.

You have 120 minutes of time in the sun before burning begins.

Re-application recommended after 1 hour or towel drying and sweating.

Advice: Cover up after this time, wear protective clothing, seek shade. We recommend that you cease sun exposure at this time.

* Halve these equations when using SPF 15 and multiply the minutes you think it will take your skin to burn un-protected by the SPF you choose to use.

In short, if your sunscreen has protective qualities to give you 120mins in the sun, re-applying does NOT mean it will double to 240mins.

Sunscreens are filters, not “blocks”. All of them will let some UV through at varying rates indicated by the SPF number. An SPF 30 product will permit 1/30th of the sunburning energy through it in the same time as it would take to suffer a minimal sunburn without any protection at all.

The whole of this definition is important to understanding how they work. It is because the sunburning dose accumulates at 1/30 of the rate that it takes 30 times as long to see the skin reddening sign that damage has occurred and repair and recovery is underway.

Sunburn may take hours to actually appear on the skin.

Once you receive a dose of sunburn, no sunscreen or re-application is going to prevent this effect. This is why it is necessary to apply your sunscreen BEFORE sun exposure.

Re-application of sunscreen is MAINTENANCE of the very first application.

It does not prolong your time in the sun; it merely gives the first application a boost, enhancing its effectiveness.

Tests carried out by our testing facility show that it will take from 6 to 10 minutes to receive burning from the sun without protection. This depends on the skin types, fair to olive. It also depends on how extreme the Sun/Heat is and varies for different Countries and States.

Wearing a Spf 30+ product for example, in theory will give you 30 times the protection before burning takes place. Re-application is necessary and recommended every two hours, due to the skin sweating or towel drying, time in and out of the sun over the course of the day, also prolonged amounts of time in the water.

The skin has seven layers, allowing the sunscreen to absorb into the skin before going out in the sun, will ensure its effectiveness; it allows it to set, if you will. If you don’t apply before sun exposure then the sunscreen will still work, but not as well. You may have already burned, so this will show up later.

The Australian standard for a sunscreen usage is that for a 60-70kg weight of person a minimum of 30gms should be used for effective sun protection.

The Governing Testing facility advises that a dose of 2mg/square cm applied to one’s body is required for coverage of any sunscreen formulation.
