Where these two actually differ
- We flag Fragrance allergens or undisclosed fragrance components and Mechanical irritation from crystal size and shape on the Credo Beauty and not on the Rahua.
- We flag Fragrance allergens and botanical sensitivizers, Preservative stability and microbial growth and Oil rancidity and oxidative byproducts on the Rahua and not on the Credo Beauty.
- The Credo Beauty is salt crystals, mineral-based scrub where the Rahua is plant-based oils, botanical extracts, aqueous surfactants, which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the Credo Beauty is the one to buy.
Both products run through the same public rubric: 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 →
