Begin with the report's actual scope
On 29 December 2025, the US Food and Drug Administration released its congressionally mandated assessment of PFAS intentionally added to cosmetic products. Using product listings available to the agency, it identified 51 PFAS in 1,744 formulations and evaluated the 25 most frequently used substances, representing about 96% of those intentionally added uses in that dataset. The report concerns the United States and the information available to the FDA; it is not a global product list, a Hong Kong regulatory decision or evidence that A New You sells any named formula. It also distinguishes intentionally added ingredients from possible contamination. Those boundaries matter before a headline is turned into a shopping rule.
Insufficient data is a finding, not a verdict
The FDA said toxicology data for most assessed PFAS were incomplete or unavailable, including gaps in use levels, dermal and oral absorption, mechanisms and dermal toxicity. This means the agency could not reach a definitive safety conclusion for most uses. It does not mean all PFAS are identical, every cosmetic is unsafe, or absence of a conclusion proves safety. The agency reported lower concern for some assessed substances under intended conditions and potential concern with substantial uncertainty for another. A useful reading therefore keeps substance, concentration, product type, exposure route and intended use together instead of treating the broad label 'PFAS' as one risk score.
Laboratory skin data adds a clue, not a personal forecast
A 2025 in-vitro study tested 30 PFAS in human skin models using diffusion cells. Under its experimental conditions, several short-chain substances crossed the model to different degrees over 24 hours, while the long-chain substances tested did not permeate in that period. The authors called for further research and standardised conditions. This is useful mechanistic evidence, but an in-vitro model is not a clinical trial, a full cosmetic formula or a measurement of one person's real-life dose. Vehicle, concentration, contact time and skin condition can change exposure, so the study should not be used to diagnose harm from a product or to promise that another product is risk-free.
Use labels and questions without manufacturing certainty
If you prefer to limit intentionally added PFAS, read the ingredient list and ask the manufacturer about the exact current formula and market. The FDA notes examples that may appear on US labels, but a single name list cannot capture contamination, reformulation or every fluorinated substance. Save the product name, ingredients, batch and purchase territory when asking a question. Stop using a product and seek appropriate help if you develop a significant reaction; do not attempt a home chemical test. A New You can help organise general skincare questions, but this article does not test products, estimate individual exposure, diagnose symptoms or confirm Hong Kong legal status or service availability.
Common questions
Did the FDA declare PFAS in cosmetics safe?
No. The report found that evidence was insufficient for definitive conclusions on most assessed uses; uncertainty is not a safety guarantee.
Did the FDA ban all PFAS cosmetics?
No. The December 2025 US report was an assessment and did not create a federal ban on every intentionally added PFAS cosmetic.
Does the skin study prove my product is harmful?
No. It was an in-vitro study of selected substances under defined conditions, not a clinical assessment of your finished product or exposure.
What information should I save?
Record the exact product, ingredient list, batch, purchase country and date so any manufacturer, regulator or clinician question is product-specific.
