Waterproof claims warrant caution until brand clarifies ingredient sources.
This eye pencil has no public PFAS disclosure or verification. Waterproof eye pencils may use PFAS-based water-resistance, though alternatives exist. Contact the brand for waterproofing specifics.

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.
Heavy metals
Iron oxides and synthetic colorants in eyeliners can occasionally contain trace lead or cadmium; Ere Perez does not publish third-party pigment testing data. The eye area's high permeability and proximity to mucous membranes makes metal contamination a concern, though typical eyeliner exposure is intermittent and localized.
Source: FDA ↗Fragrance allergens and undisclosed fragrance components
Plant-based beauty brands often use essential oils or botanical extracts as fragrance; these can trigger contact dermatitis or photosensitivity in sensitive individuals. Ere Perez does not disclose fragrance components on available product labeling, and the eye area is prone to allergic reactions.
Wax degradation and rancidity
Wax-based products with plant oils can oxidize or turn rancid over time, especially if stored in heat or light. Degraded wax may produce irritant compounds; shelf life and storage conditions are not specified for this product.
PFAS
The unspecified waterproofing mechanism is a material gap; it could involve silicones, acrylates, or other film-formers with their own safety profiles. Without disclosure, users cannot assess reproductive, allergenic, or bioaccumulative risks of the actual formulation.
Source: ATSDR ↗Bacterial contamination risk
Wax-based pencils stored in pencil form (not sharpened regularly) can harbor bacteria if not kept clean or if applied near the eye margin repeatedly. Eyeliner pencils are high-touch products and should not be shared.
The full breakdown
What it's made of and why it matters
Ere Perez Eye Pencil is a wax-based eyeliner containing pigments and binders formulated for waterproofing. Wax formulations typically use oils and thickeners to adhere to the eyelid; the specific waterproofing agent is not disclosed on available product information. The eye area is highly permeable and absorbs compounds readily, making ingredient transparency critical for products applied directly to mucous membranes and thin skin.
The brand's record and disclosure
Ere Perez is a clean beauty brand that emphasizes natural and plant-based ingredients, but public documentation on this specific product's complete formulation and waterproofing mechanism is limited. The brand does not appear to have published third-party certifications (such as COSMOS or EWG verification) for this line. No established recalls or safety controversies for this product are on record, but the silent stance on PFAS sourcing in waterproof products represents a transparency gap typical of many indie beauty brands.
How it compares in its category
Waterproof eyeliners commonly use either silicone polymers, film-forming resins, or fluorinated compounds to achieve water resistance. Ere Perez's wax-based approach is less common than synthetic polymer alternatives and may be more stable than products relying on undisclosed waterproofing chemistry. However, without explicit ingredient declaration of the waterproofing mechanism, it is harder to assess relative safety compared to brands that specify polymer type (silicone vs. acrylate) or openly exclude PFAS.
If you buy it
Apply only to the eyelid margin, avoiding direct contact with the eye or waterline. Remove daily with gentle cleanser or oil; prolonged wear can trap bacteria and debris. Discontinue use if redness, itching, or irritation develops, as the eye area is sensitive and wax-based products may not suit all skin types. Contact the brand directly to request the full waterproofing agent disclosure before purchase if PFAS avoidance is a priority for you.
