Mac Prep + Prime BB Beauty Balm SPF 35
Waterproof cosmetics carry PFAS risk; MAC discloses nothing so skip until clarity emerges.
MAC Prep + Prime BB Beauty Balm SPF 35 contains waterproofing and long-wear claims typical of cosmetics that may use PFAS water-repellent coatings. MAC provides no public disclosure about PFAS presence or absence.

Material
emulsion base with silicones, water, mineral pigments, SPF actives
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
PFAS
Waterproof BB creams almost always require fluorinated water-repelling agents; MAC has not disclosed ingredient lists or PFAS-free status, making the presence of PFAS compounds highly probable even though not explicitly confirmed for this SKU.
Source: ATSDR ↗Fragrance allergens and undisclosed fragrance components
MAC products typically use proprietary fragrance blends; while 1,4-dioxane contamination is rare in modern cosmetics, undisclosed fragrance chemicals can trigger contact dermatitis or respiratory sensitivity in sensitive individuals.
Bacterial or fungal growth in silicone emulsion base
Silicone-water emulsions require preservatives; if the container is exposed to moisture or contamination, preservative efficacy can degrade, risking biofilm or mold growth over time, especially in warm bathrooms.
What’s reassuring
Heavy metals
Mineral-based pigments (iron oxides, titanium dioxide) in cosmetics are regulated and seldom contain detectable lead or cadmium when sourced from reputable suppliers; no recalls or testing concerns are on record for MAC's pigment lines.
Source: FDA ↗Talc contamination or asbestos risk
This product is a liquid BB cream, not a powder, so talc is not a typical ingredient; no asbestos risk is applicable to emulsion-based formulations.
The full breakdown
What it's made of and why it matters
MAC Prep + Prime BB Beauty Balm is a silicone-water emulsion designed for long wear and water resistance. Waterproof cosmetics typically require fluorinated compounds (PFAS-class chemicals) to repel moisture; silicones themselves are not hazardous, but the formulation's water-resistance claim raises the likelihood of fluorinated additives. Mineral pigments used for coverage are generally safe, but the SPF 35 actives (likely zinc oxide or titanium dioxide) are non-problematic in finished form when not inhaled as powder.
The brand's record and disclosure
MAC Cosmetics has not published a public list of PFAS-containing ingredients or committed to phasing them out, unlike some competitors (e.g., Beautycounter, Honest Company). The brand does not highlight fragrance transparency, heavy metal testing, or formaldehyde-releaser avoidance in marketing materials. No major recalls or safety controversies tied to this specific product line are on public record. This silence is the primary concern: the absence of disclosure does not mean the product is safe, only that MAC has not chosen to lead on this issue.
How it compares in its category
BB creams and tinted moisturizers often contain PFAS in waterproof formulations; this product sits in the mainstream mass-market tier where such ingredients are common and rarely disclosed. Brands with explicit PFAS-free claims (like Glossier, RMS Beauty) are becoming more visible but cost more. The silicone base itself is standard; the water-resistance claim is the differentiator that drives PFAS risk, making this product riskier than non-waterproof tinted moisturizers in the same price range.
If you buy it
Assume potential PFAS exposure from the waterproof formulation and use sparingly if concerned about bioaccumulation. Apply only to face and blend well; avoid contact with lips or eyes where absorption may be higher. Do not heat the product or store it above 25C (silicones can alter under heat, though leaching is not the primary concern). Replace every 12 months after opening; silicone-based products can harbor bacteria if water or saliva enters the container. If you have sensitive skin, patch-test first; fragrance and mineral pigments occasionally trigger dermatitis.
