Drunk Elephant B-Hydra Intensive Hydration Serum
Lower concern; aqueous serum formulation has no known PFAS vectors.
The water-based serum with glycerin and hyaluronic acid shows no PFAS-typical ingredients like Teflon-family coating or nonstick treatments. The product category presents minimal risk for intentional PFAS addition.

What Drunk Elephant B-Hydra Hydration Serum is made of, ingredients and materials
B-Hydra is a lightweight, water-based serum built around glycerin and hyaluronic acid, both common humectants that draw moisture into skin. The formulation contains no emulsifiers, silicones, or oils, which reduces the number of synthetic compounds that could pose stability or irritation risks. Water-based serums like this are inherently lower-risk than oil-based or cream-based products because they have fewer chemical preservative demands and no risk of oxidation-driven degradation common in lipid formulations.
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.
Fragrance allergens / botanical sensitizers
The formula includes fragrance components and plant extracts (e.g., Watermelon Fruit Extract) that may trigger contact dermatitis or photosensitivity in susceptible individuals. No formaldehyde-releasing preservatives or 1,4-dioxane are documented in this product, so systemic fragrance hazard is limited to topical irritation.
Container leachables (packaging hazard)
B-Hydra is packaged in opaque plastic bottles; if the plastic is uncoated polycarbonate or low-quality polyethylene, minor BPA or phthalate leaching is theoretically possible over extended storage, though aqueous, low-pH environments minimize this risk compared to oil or alcohol-based products.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
Standard cosmetic preservative systems used in water-based serums (typically phenoxyethanol or plant-derived alternatives) do not release formaldehyde at approved concentrations. No evidence of formaldehyde donors in B-Hydra's published formula.
Source, ATSDR ↗Heavy metals
This serum is colorless to pale yellow with no pigments or mineral additives; iron oxides, titanium dioxide, and other pigment-bound metals are absent. No hazard vector exists for metal accumulation.
Source, FDA ↗Microplastics
The formula is water and glycerin based with no silicone polymers, polyethylene beads, or microplastic fillers documented. Hyaluronic acid is a natural polymer not classified as microplastic.

The brand's record and disclosure
Drunk Elephant has built a public identity around 'clean beauty' and transparency, publishing ingredient lists without heavy obscuring. The brand does not actively claim third-party certification (organic, cruelty-free certs are absent from marketing) but has maintained a stance of avoiding commonly flagged ingredients like phthalates and parabens. No major product recalls or safety controversies specific to this line are on public record; the brand's silence on PFAS aligns with industry-wide inaction rather than indicating a hidden problem.
How it compares in its category
Water-based hydrating serums are among the lowest-risk cosmetic category because they lack complex emulsion chemistry and heavy preservative loads. B-Hydra is typical of premium hydration serums in structure but commands a higher price point ($68 USD) compared to drugstore alternatives (CeraVe, Neutrogena serums at $10-20), with no measurable safety advantage, only brand positioning. Functionally equivalent products use nearly identical humectant blends and pose similar negligible hazard profiles.
If you buy it
Store in a cool, dry place away from direct sunlight to preserve the hyaluronic acid and glycerin activity; neither degrades with heat, but UV exposure can damage packaging. Use within 12 months of opening; water-based serums are vulnerable to bacterial colonization if contaminated with wet fingers or applicators, so avoid double-dipping. Discontinue use immediately if redness, burning, or itching develops; fragrance and botanical extracts in the formula can trigger sensitivity in reactive skin types, though this is a personal tolerance issue, not a product defect.
