Why This Matters
Independent standards help customers look beyond marketing
Certifications provide independent standards rather than relying solely on brand marketing. As customers become more interested in transparency, recognised standards can make product information easier to understand.
Many of the formulations Barely Skin provides are independently COSMOS Certified Natural or COSMOS Certified Organic. Finished formulations carrying these certifications have been independently assessed against recognised standards.
FAQs
Questions, answered clearly
What is COSMOS?
COSMOS is an independent cosmetic standard used for natural and organic cosmetics. It looks at formulation requirements, ingredient origin and wider environmental considerations.
What is the difference between Natural and Organic?
Natural and organic are related, but they are not identical. Organic certification usually has additional requirements around organically farmed ingredient content.
Does Natural mean Organic?
No. A product can be natural without being organic. The exact meaning depends on the standard or claim being used.
Does certification make a product better?
Certification does not automatically mean a product is better for every person. It means the product has been assessed against a recognised standard, which can support transparency and trust.
What does Dermatologically Tested mean?
Dermatologically tested usually means a product has been tested under dermatological supervision. It should still be read alongside the product's full ingredient list and suitability information.
Why does independent certification matter?
Independent certification gives customers an extra layer of confidence because the finished formulation has been reviewed against criteria beyond a brand's own marketing language.
What does Natural Origin Percentage mean?
Natural origin percentage is a way of communicating how much of a formulation is from natural-origin sources. It should be read alongside the product's full certification and ingredient information.
