Level of Evidence. What is it and how is it helpful?

In our efforts to achieve transparency, we have been working hard on a new feature - Ingredient Evidence. This information provides a closer look at the possible beneficial ingredients, and for your convenience, we have evaluated the level to which the evidence supports any beneficial claims, so you can see the documented effects of the ingredients for your condition yourself.

To read more about what are the active ingredients - click here.

Each active ingredient has been analysed for level of evidence from levels A to D.

  • In the bottom of the hierarchy the exploratory, laboratory “in-vitro” studies are placed. As you move up the triangle, the studies get more precise, use control groups and are usually based on more people. This makes them more reliable and precise when concluding. The highest ranked studies are the double-blinded Randomised Controlled Trials (RCTs).

Things to keep in mind when referring to the Level of Evidence:

  • The level of evidence is specific to the condition, meaning there may be a higher level of evidence for an ingredient for one condition than another.
  • An ingredient may have a low evidence grade, but this does not always mean it is ineffective. The grade only relates to the amount of independent scientific evidence that exists to support its claims. Make sure to read more about the ingredient to see exactly how it benefits the skin and its success rate among studies.

By providing this analysis we hope to bring more nuance in consumption, steer away from name dropping without evidence and show that a critical mindset is highly valuable when making the right decisions for your skin.

We believe that evidence, data and an honest approach is what will successfully equip us on our journey to healthier skin.
