Clean Beauty Experts


Our products are all day use, so choose wisely. Unlike products that are full of harsh chemicals such as phthalates, GMO’s paraben, artificial sulfates and other cheap synthetic ingredients which have been linked to hormone disruption, harmful to our planet, aquatic ecosystems and people that are safe and effective.

At Periodic lab, we back “clean” with the strongest standards in retail today.


Transparency around ingredient sourcing, purity, and composition—as well as the suppliers’ and brands’ and processes—is crucial to clean. If this information is kept in a black box how can we possibly know if it is clean?


In order for “clean” to have real meaning, brands need to walk the walk. And in order to do that, they need guidelines—and required compliance always helps to make it real, too. Enter The Periodic Lab Clean Standard, the strongest standard in retail.

Periodic Lab has always had its Dirty List that contains over 2,700 specific ingredients and types of ingredients that are used in mainstream beauty products, but Periodic Lab prohibits due to safety and/or sustainability reasons.

  • Use official ingredient terminology (called INCI) and use ingredient source codes where possible
  • Obtain documentation on their ingredients’ composition, purity and sourcing information
  • Conduct basic consumer safety (on humans…that volunteer!) and product stability testing
  • Back up product and ingredient claims
  • Be transparent about “fragrance”—at a minimum they must categorize the type of fragrance they use, and we encourage full disclosure of all fragrance ingredients. Learn More …and more.
  • None of this is currently required by the US government or other retailers.
  • Periodic Lab will continue to evolve over time, especially in light of new data and innovation. We learn from allies up and down the supply chain, and Periodic Lab offers our brand partners support in the journey to be compliant. Raising the bar on safety, sustainability and transparency is not easy, but most worth while undertakings aren’t! Doing “clean” together as allies make it


What do we know about the safety of the ingredient? Does it present a risk to the user, or to the environment, whether by itself or as used in a beauty product?


Is the ingredient sourced from nature, is it synthetic or is it some combination (e.g. naturally-derived)? Is there more than one source for this ingredient, and if so, is one better for people or the environment?


How is this ingredient grown, mined or made? Was it shipped around the world during its production? Are there sustainability concerns, e.g. plantation farming practices?


Is this ingredient linked to unfair labor conditions or wages? Is there any insight into the supply chain to understand if animals are treated humanely?
