What MAC Squirt Plumping Gloss Stick is made of, ingredients and materials
MAC Squirt Plumping Gloss Stick uses a proprietary waterproof lip gloss base with plumping actives (likely peptides or capsaicin-based irritants to create temporary fullness). The waterproof claim is the concern, cosmetic waterproofing often relies on fluorinated compounds (PFAS) to repel moisture, though MAC has not disclosed whether this product uses them. The gloss formula is applied directly to lips and oral mucosa, making ingredient transparency critical for ingestion and skin sensitization risk.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
MAC has not disclosed whether the waterproof claim relies on fluorinated compounds or PFAS. Lip glosses with waterproof properties commonly use these compounds, which persist in the body and environment; unconfirmed here but plausible given the product's marketing.
Source, ATSDR ↗Plumping agents and contact sensitization
Plumping glosses typically use capsaicin or synthetic peptides to trigger mild irritation and vasodilation for temporary fullness. Individuals with sensitive lips or capsaicin sensitivity may experience burning, swelling, or allergic contact dermatitis.
Fragrance allergens
MAC lip products often contain fragrance compounds and essential oils listed as 'fragrance' or 'parfum' under current regulations, which can mask allergens like limonene or citral. Individuals with fragrance sensitivity or lip dermatitis should patch-test or avoid.
Ingestion of cosmetic waxes and polymers during normal use
Lip gloss is applied directly to oral mucosa and inevitably ingested during eating or drinking. While modern cosmetic waxes and polymers are regulated for incidental ingestion, chronic low-level exposure to synthetic polymers (including suspected PFAS) has not been extensively studied in vulnerable populations.
What’s reassuring
Heavy metals
No recalls or reports of lead, cadmium, or other heavy metals in MAC lip products exist on record. MAC adheres to FDA cosmetic color regulations, though independent third-party testing of this specific product is not publicly available.

The brand's record and disclosure
MAC Cosmetics (Estee Lauder subsidiary) does not publicly disclose fluorinated polymer or PFAS use in lip products or provide ingredient lists beyond required labeling. The brand has not signed pledges to phase out PFAS in cosmetics, unlike some competitors. No recalls or safety controversies specific to MAC lip glosses are on record, but the silent stance on waterproof chemistry raises red flags for consumers seeking transparency.
How it compares in its category
Most long-wear lip glosses carry similar waterproof chemistry opacity; MAC's formula is mid-range in terms of plumping intensity compared to brands like Volumizer or Lip Plumper variants. Alternatives from brands like Burt's Bees or Honest Beauty publish fuller ingredient lists and avoid waterproof claims that typically hide PFAS. MAC's luxury positioning does not correlate with better safety disclosure in this product line.
If you buy it
Apply sparingly to avoid excess ingestion during eating or drinking. Do not use if you have lip sensitivity, allergic reactions to synthetic plumping agents, or latex sensitivity (check cap). Replace every 12-18 months or if the formula separates or dries out. Avoid applying near the eye area; if irritation occurs, discontinue and rinse thoroughly with water.
