The star ratings go from three to five, with the five-star rating pertaining to the sunscreens whose UVA protection is at least 90% of its UVB protection.Īlthough well-meaning, this system can be misleading since it measures how evenly the sunscreen protects in the UVA range, not how strong (thus, how effective) that UVA protection is over a period of time. It is meant to give consumers more information on how much UVA protection a sunscreen provides, via a star ratings system. The UV star rating system was developed by a drugstore chain based in the United Kingdom. What is the UV star rating – and why don’t Paula’s Choice sunscreens have it? Each one reliably falls in the range of offering high protection (SPF 30–49.9) or very high protection (SPF 50 and greater). All Paula’s Choice SPF products have passed this test and provide broad-spectrum protection.Įvery Paula’s Choice sunscreen undergoes US Food & Drug Administration (FDA) and Colipa (Europe’s cosmetic regulatory body) testing. This result is also referred to as UVA-PF (protection factor). In order to pass, the sunscreen’s UVA protection must be at least one-third of its UVB protection. If a sunscreen passes the critical wavelength test, it can legally state “broad spectrum” on its label. The critical wavelength test is considered extremely reliable because it uses the full spectrum of UV radiation (UVA and UVB) skin is exposed to in real-world settings (4).Ĭurrently, the SPF rating on any sunscreen is still about UVB protection. They’re also subject to a critical wavelength test which evaluates the broad-spectrum protection. Sunscreens produced in the United States and sold throughout the European Union and United Kingdom must go through rigorous testing to determine their SPF rating. How are sunscreens from the United States tested? We hope that you find this research-supported information reaffirming and reassuring. Because of these established-beyond-a-doubt dangers, we should be far more worried about the sun than sunscreens.īelow we address common questions from our European consumers about sunscreens and UV filters. Avoiding sunscreen and not following sun-smart behaviour isn’t just detrimental to your skin, it’s bad for almost every aspect of your health (3). It not only affects everyone’s skin but also their eyes and internal organs (2). Research has proven beyond any doubt that the ultraviolet (UVA and UVB) radiation the sun emits is the most prevalent carcinogen on our planet. While sunscreen safety studies are ongoing and some knowledge gaps exist, from the dozens of studies we’ve reviewed there’s no evidence anyone should give up sunscreen and risk the consequences for their skin. Decades of people using sunscreen and extensive, world-wide research has proven this to be true (1). In fact, when applied as they should be (which is described on every sunscreen’s label) they save lives and prevent an extensive range of skin problems.
