Lola · Period Underwear
The Period Company The High Waisted Period. in Cotton For Medium Flows Women's
Lower PFAS concern for core material; period-care padding rarely uses water-repellent treatments requiring PFAS.
Lola's high-waisted period underwear is primarily cotton, which inherently carries lower PFAS risk compared to waterproof apparel or non-stick coatings. The brand does not disclose PFAS avoidance practices or certifications, so full supply-chain confidence is limited. No public lab data or recalls flag this product.

The full breakdown
What it's made of and why it matters
Lola's High Waisted Period underwear uses cotton fabric as the primary material, with an absorbent pad core designed to handle menstrual flow. Cotton itself is a natural fiber with low inherent toxicity risk, though chemical processing during manufacturing (dyeing, finishing) is the primary exposure pathway. The pad core construction typically uses cellulose-based absorbent layers; Lola has not publicly detailed whether their padding includes superabsorbent polymers (SAP) or other synthetic additives. Direct skin contact during extended wear means residual chemicals from processing, dyes, and finishes warrant attention.
The brand's record and disclosure
Lola maintains a direct-to-consumer model and emphasizes ingredient transparency on their website, but does not publish third-party safety certifications (GOTS, Oeko-Tex) or detailed chemical testing results for their period products. The brand has not faced major recalls or public safety complaints on record as of available sources. Their PFAS stance remains undisclosed, though period-care padding typically avoids water-repellent treatments that would require fluorinated compounds. Lack of proactive transparency is a minor transparency gap but not evidence of hazard.
How it compares in its category
Period underwear as a category has fewer established safety standards than menstrual pads or tampons; Lola's cotton-based design sits mid-range between fully synthetic alternatives (polyester-nylon blends with higher dye and flame-retardant risk) and certified organic cotton brands (Thinx, Dear Kate) that carry third-party testing badges. Lola's positioning emphasizes affordability and comfort over certification, meaning end-users assume slightly higher burden for verifying chemical safety. Cotton underwear generically poses lower microplastic and heavy-metal-dye risks than synthetic-heavy competitors.
If you buy it
Wash before first use to reduce residual dyes and finishes from manufacturing. Machine wash in warm water with mild detergent; avoid chlorine bleach and high heat (dry on low or air dry) to preserve fabric integrity and avoid dye instability. Replace underwear when elastic degrades, fabric thins, or absorbency visibly declines, typically every 1-2 years with normal use. If skin irritation occurs after purchase, discontinue and consider whether it correlates to dye sensitivity or pad-core material rather than assuming defect.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Azo dyes and synthetic colorants
Cotton fabric dyeing commonly uses azo dyes; Lola does not publicly confirm use of restricted or non-allergenic dye classes. Risk is mild for short-term skin contact but dermatitis is possible in users with dye sensitivity, particularly in repeated laundering that may release residual dye.
Formaldehyde-based finishing resins
Cotton garments may be treated with formaldehyde resins during finishing to improve wrinkle resistance or durability; Lola does not disclose whether their fabric undergoes such treatment. Formaldehyde off-gassing is low in room-temperature garments but elevated during hot laundering and can trigger respiratory or skin reactions in sensitive individuals.
Heavy metals in dyes (antimony, lead, chromium)
No recalls or test failures on record for Lola period products. Standard cotton dyes pose minimal heavy-metal bioaccumulation risk; direct skin contact during menstruation does not create significant absorption pathway for trace metals in fabric colorants.
Absorbent core polymer toxicity (if SAP used)
Lola has not disclosed the composition of their pad core absorbent material. If superabsorbent polymers (acrylic-based SAP) are used, these are generally well-established as safe for skin contact; however, microplastic shedding during wear and laundering cannot be ruled out without detailed product specifications.
Bacterial growth and hygiene during wear
Period underwear that remains in contact with menstrual fluid for extended periods creates an occlusive, warm, moist environment. This is a use-case hygiene concern rather than a material toxicity issue, but proper laundering and timely replacement are essential to prevent bacterial proliferation and associated odor or infection risk.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
