SKINTELLI, a New York-based biotechnology brand of EpigenCare Inc., develops at-home skin antioxidant self-tests and DNA-based epigenetic skincare tests. Its kits measure current skin quality or the antioxidant capacity of skincare products, then use the results to guide personalized product recommendations. The company’s proprietary STAMP™ technology profiles DNA methylation in skin-related genes rather than relying solely on static genetics or questionnaires.
