Where these two actually differ
- We flag Fragrance allergens and sensitizers and Preservative system stability and microbial growth on the Ilia Beauty and not on the MAC.
- We flag Fragrance allergens and undisclosed fragrance compounds, Microbial contamination from open-jar or finger-dip application and Contact irritation or sensitization from silicone or emollients on the MAC and not on the Ilia Beauty.
- The Ilia Beauty is liquid cosmetic serum, presumed water and glycerin base where the MAC is pigments, silicone, glycerin in liquid/cream base, 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 →
