Where these two actually differ
- We flag Preservative system stability and microbial growth on the Ilia Beauty and not on the MAC.
- We flag 1,4-dioxane (synthetic fragrance contaminant) on the MAC and not on the Ilia Beauty.
- Both carry a flag for Fragrance allergens and sensitizers, so neither choice avoids it.
- The Ilia Beauty is liquid cosmetic serum, presumed water and glycerin base where the MAC is liquid foundation/concealer, silicone-based emulsion with pigments, 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 →
