Cosmetic Contamination Kit

Personal care products are not subject to pre-market FDA review in the United States.

Coming soon
What it tests for
  • Microbial pathogens (bacterial / fungal)
  • Parabens / preservatives
  • Heavy metals (Lead, Arsenic, Cadmium, Mercury)
  • Fragrance allergens (regulated list)
  • Oxidation / rancidity markers
Why it matters

Cosmetics in the U.S. are largely not reviewed by the FDA before sale. Contaminated mascara, lotion, or lip products can carry bacteria or fungi that cause eye and skin infections, while some imported products have been found adulterated with lead or mercury.

Heavy metals in skin-lightening creams and some lipsticks are absorbed over time; mercury in particular damages the kidneys and nervous system.

How to collect your sample

Swab or scoop a sample of the product into the sterile vial using gloves, seal, and return per instructions.

How the lab analyzes it

Microbial culture detects bacterial and fungal contamination; ICP-MS measures heavy metals; LC-MS/MS quantifies preservatives and fragrance allergens; oxidation markers flag rancidity.

Did you know
  • Skin-lightening creams are a notorious source of mercury contamination worldwide.
  • An opened mascara is a warm, moist environment ideal for bacterial growth - a key reason for expiration windows.
The Sacred Sampling standard

Laboratory data — not estimates.

Independently operated, with no ties to filter or remediation companies. Every sample is analyzed by an accredited partner laboratory under EPA-referenced methods, with a documented chain of custody — and your data is yours.
