Where these two actually differ

  • We flag Heavy metals in botanical extracts and Microbial contamination or rancidity from plant oils on the Osea and not on the Weleda.
  • We flag Oil oxidation and rancidity on the Weleda and not on the Osea.
  • Both carry a flag for Fragrance allergens, so neither choice avoids it.
  • The Osea is undaria algae extract, plant oils where the Weleda is Plant oils, butters, waxes, which is most of the difference in these two grades.

Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
