This week, we’re welcoming Jackie Burke, founder of safe-for-sensitive ears jewelry brand, Tini Lux. Jackie left a career in engineering to found Tini Lux after years of frustration with so-called “hypoallergenic” earrings that failed to live up to their promise. Now, the style-whiz entrepreneur is making the case for medical-grade titanium earrings to live alongside beauty products in the aisles of Sephora.
