Where these two actually differ
- We flag Heavy metal pigments (lead, cadmium, iron oxide impurities), Azo dyes and synthetic colorants (allergic sensitization) and Fragrance and flavor oils (allergen, aspiration risk) on the MAC Fix+ and not on the MAC Fix+.
- We flag Heavy metals in colorants (pigments/dyes), Polymer film degradation and micro-particle shedding and Undisclosed waterproofing chemistry (likely PFAS-class risk) on the MAC Fix+ and not on the MAC Fix+.
- The MAC Fix+ is wax, oils, pigments, emollients (typical lipstick base) where the MAC Fix+ is pigments, waxes, film-forming polymers with waterproof binder, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the MAC Fix+ is the one to buy.
- We are less certain about the MAC Fix+ grade, at 42% confidence against 72%, because it discloses less.
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 →
