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-sensitising medications, you may need a higher SPF.
Extended periods of sun exposure also call for a higher SPF. Hawaiian Tropic® Sun Care offers a full range of sun protection products up to 80 SPF.
SPF ratings are determined in a laboratory setting. SPF-30 products are estimated to allow 1/30 of the sun’s burning rays to get through to the skin (protects against almost 97% of the sun’s burning rays). SPF-50 products are estimated to allow 1/50 of the sun’s burning rays to get through to the skin (protects against approximately 98% of the sun’s burning rays). Actual protection may vary and will depend on the user applying adequate amounts. Reapply at least every 2 hours or as directed on the package to help ensure adequate protection.
