Research Tests

Our product development transcends rudimentary microbial and heavy metal safety benchmarks. Rigorous dermatological evaluations on sensitive skin, alongside targeted efficacy assessments, underscore our commitment to both performance and safety—ensuring every formulation is substantiated by empirical evidence, not merely theoretical conjecture.

Key validations include:

  • ​Microbiological and Heavy Metal Screening (Total colony count, mold and yeast count, thermotolerant coliforms, Staphylococcus aureus, Pseudomonas aeruginosa, mercury, arsenic, lead, cadmium)

  • Trypsin-like activity assays for anti-allergy efficacy.

  • Neutrophil/IL-6 gene expression analysis for anti-inflammatory benefits.

  • Zebrafish models for assessing hydration and irritancy.​

This comprehensive approach guarantees that each product we engineer delivers tangible results without compromising user well-being.
