About This Guide
Sun Protection and Products Guide is an independent reference site about sun protection. It explains how sunscreen and sun-protective clothing work, what the ratings on the label actually mean, and how to use both properly.
The guide has covered this subject for many years and has been cited as a general reference by health publications, educators and researchers looking for plain-English explanations of SPF and UPF.
What this guide covers
- Sunscreen — what SPF measures, how the different ratings compare, what broad spectrum means, the difference between mineral and organic UV filters, and how storage and expiry affect a product.
- Sun-protective clothing — how UPF is tested and rated, how ordinary clothing compares, and what reduces a garment's protection over time.
- Practical use — how much sunscreen to apply, how often to reapply, the areas people commonly miss, and choosing sunscreen for children.
- Background — the history of sunscreen and the ABCDE recognition criteria for melanoma.
How this guide is written
The content is a plain-English summary of published guidance from health authorities, dermatology bodies and the international standards that govern how sunscreen and fabric are tested.
The sources behind each page are listed on the references page. Where guidance differs between countries, the guide says so rather than presenting one national position as universal.
Pages are reviewed when the underlying standards or regulatory guidance change. Testing standards for SPF and UPF are revised periodically, and labelling rules differ between markets, so the detail on a label is not always comparable from one country to another.
What this guide is not
- It does not sell anything. No products are sold on this site and no brands are endorsed. Where a product type is described, it is described generically.
- It is not medical advice. The guide explains general principles. It cannot assess an individual's skin, risk factors or medical history. See the disclaimer.
- It does not replace local guidance. Ultraviolet levels vary enormously by latitude, altitude, season and time of day. Advice that suits one part of the world may be inadequate somewhere with a higher UV index.
