Q1: What specific safety aspects are evaluated for exosomes intended for cosmetic use? A: We conduct a comprehensive range of assessments, including in vitro cytotoxicity, skin irritation, ocular irritation, sensitization, and microbiological testing, to ensure that the exosomes meet strict global cosmetic safety standards.

Q2: How do you test for skin irritation without using animal models? A: We employ advanced 3D reconstructed human epidermis (RhE) models and robust in vitro cell-based assays. These ethical and highly predictive methods are a core part of our skincare exosome safety evaluation, providing reliable data that aligns with modern cruelty-free industry trends.

Q3: Are your testing protocols compliant with international cosmetic regulations? A: Yes. All our evaluation processes are designed in strict accordance with major global regulatory guidelines, such as those established by the FDA and the EU Cosmetics Regulation, ensuring your exosome-based skincare products are ready for market approval.
