At Facetheory we are science-led, results-driven and ethically-committed. There is a wealth of conversation out there regarding the topic of SPF but we choose to adhere to the latest research and guidance from the CTPA. If you aren't familiar with them, the CTPA are a highly respected independent industry body that works with scientists, regulators, and brands to ensure cosmetic products sold in the UK meet strict safety rules. There is no regulated definition or scientific substantiation for the "reef safe" claim and as a result, the use of it can be considered greenwashing. Brands have been taken to court over such claims.
Brands and sunscreens that claim ‘reef safe’ often make this claim based on the assumption that avoiding certain UV filters is better for coral reefs; however, this assumption is not based on sound science, and claiming sunscreens are ‘reef safe’ is misleading to the consumer. As a result of a 2016 study, past media reports have suggested that the UV filter Benzophenone-3 (also known as Oxybenzone) can affect coral reefs; however, the study was carried out in a laboratory and does not replicate the natural environment, and it does not make a link between the use of UV filters in sunscreen and damage to coral in our ocean. There is no proven link between the use of UV filters and damage to coral in our ocean. More information on sunscreens can be found in CTPA’s consumer-facing website: https://www.thefactsabout.co.uk.
