It was once widely believed that a 15 SPF product offered sufficient UV protection under most conditions. Over the last few years that school of thought has changed. It is now known that, often more sun protection is desirable.

It’s ideal to select a sunscreen that blocks enough UV rays to adequately protect your skin type. Use the Sun Protection Factor Guide to help determine your skin type and appropriate SPF. If you have very fair or sensitive skin, a history of skin cancer, or take photo-sensitizing medications, you may need a higher SPF.

Choose a sunscreen with “broad spectrum” protection. Sunscreens with this label protect against both UVA and UVB rays. All sunscreen products protect against UVB rays, which are the main cause of sunburn and skin cancers. But UVA rays also contribute to skin cancer and premature aging. Only products that pass a certain test can be labeled “broad spectrum.” Products that aren’t broad spectrum must carry a warning that they only protect against sunburn, not skin cancer or skin aging.

Spray and powder sunscreens are mineral-based and contain nanoparticles that can enter the bloodstream and cause various health issues . Avoid such products and stick to cream-based sunscreens.

How much sunscreen should you apply and how often?

It’s a pain to apply and reapply sunscreen but it’s vital if you’re planning on sitting out in the sun. A good rule to follow is one teaspoon per body part that’s exposed to the sun. For example, one teaspoon for the face, one for each arm and leg and so on. Remember, if you don’t apply enough sun cream, your level of protection is reduced.

Always apply sunscreen 30 minutes before you’re out in the sun and top up just before. Once in the sun reapply every couple of hours or immediately if you’ve been swimming or sweating – even if your sun cream claims to be water resistant.
