“All-natural” product claims can be extremely misleading because there’s actually no official government organization that endorses the term, much less pinpoints a specific definition for it. This means that when something claims to be “natural,” it’s purely marketing.
That being said, many brands will go through third parties (ECOCERT, for example) to get a special certification to be able to call themselves “all-natural.”
You’re probably wondering how these types of organizations define the phrase in these instances, and here’s how… They claim that it means that no single ingredient in the product itself was made in a lab. But when it comes to sunscreen, here’s the truth: all SPF – including 100% mineral SPF – is produced synthetically in a lab. This is to ensure that the materials don’t contain any impurities or traces of hazardous materials…and that the formulation lives up to its protection claims. So if we’re going by this definition of “natural” that many companies adhere to, then no sunscreens can be considered natural.
