“Application of organic sunscreens should be done 15-30 minutes before going out into the sun. Waterproof or water-resistant sunscreens should be used to diminish the need for reapplication after swimming followed by towelling, friction with clothing or sand, and sweating.”

• Don't rely simply on statements of "protection" against UVA since some researchers believe many of these sunscreens only offer an SPF of 3 or 4 for UVA rays, even if the SPF is much higher for UVB rays. Instead, look for a sunscreen labeled "broad spectrum" that contains zinc oxide and has a minimum SPF rating of 15.

 

• Apply sunscreen about 20 minutes before sun exposure to allow it time to "set up" on the skin. Reapply every two hours when swimming or sweating.

• Use at least 1 full ounce of sunscreen per adult per application (SPF ratings are based on this amount). Using a smaller amount of SPF 30 does NOT equal a greater amount of SPF 15!

 

• SPF Sunscreen Recommendations based on skin type:

• Type 1 (always burns, never tans): 30 SPF

 

• Type 2 (usually burns, tans with difficulty): 20 SPF

• Type 3 (sometimes burns, sometimes tans): 15-20 SPF

 

• Type 4 (burns minimally, always tans): 15 SPF

• Type 5 (rarely burns, tans profusely): 15 SPF

 

• Type 6 (never burns, deeply tans): 15 SPF

• Other sunscreen tips:

 

• Pay special attention when applying sunscreen to your ears, nose, shoulders and tops of feet.

• When snorkeling, pay particular attention to the back of the calves and thighs.

Generally an SPF 15 will offer protection of about 2 hours depending upon skin type - much less if you tend to burn easily.  An SPF 30+ will off protection for up to 4 hours, again depending upon skin type.
The protective level of a sunscreen plateaus around SPF 30-32, anything more than that is merely misleading by the use of higher SPF numbers. In fact you would be lucky if an SPF 60 or higher gave you more than an extra mintue or two in the sun. What you do get however, is an increase in the amount of toxic chemicals you apply to your skin.  Companies like to show their consumers that they have an SPF of 60 or 100 etc and yet these do not offer any more protection than an SPF 30+. It would be nice to think that an SPF 100 would offer 3.5 times more protection than SPF 30 but it is truly not the case.  The FDA is bringing into force a 'reality check' on these sorts of unfounded claims via their Final Monograph on Sunscreens, where they specify that the highest rating permissible will be SPF 30+. Whilst this Final Monograph has not been introduced into legislation as yet, we will continue to abide by their suggestions and maintain the integrity of our product.  UV natural's range of SPF 30+ actually performs and tests at an SPF 45, yet we do not wish to join the misleading advertising and therefore only label our product at SPF 30+.

he FDA has two categories to describe water resistance in a sunscreen. "Water Resistant" means that the sunscreen retains its SPF rating after 40 mins in the water and "Very Water Resistant"  means it will do so after 80 mins in the water.  Even though our sunscreen surpasses those requirements easily, it is the official description we must use by law. The UV Baby & UV Adult are "Water Resistant" and the UV Sport & UV Golf are "Very Water Resistant".
Cover all exposed skin liberally.
