Lumineux Versus Strips: Surprising Sensitivity-Free Whitening Expert Formulated We were intrigued by Lumineux’s promise of whitening without the usual sensitivity—especially as we’ve tried other strips that left our teeth tender. The 9-treatment kit feels sleek and professional, with a dentist-formulated peroxide-free formula that cleanses gently yet effectively. We appreciate how enamel-safe it is, and the effects are subtly noticeable without compromising comfort. The application is simple, and the lack of peroxide means we can use it regularly without worry. While traditional strips target sensitivity, Lumineux proves whitening doesn’t have to involve it. Our teeth feel bright and smooth, and oddly, ours haven’t flared up at all. It’s a refreshing alternative that defies expectations, blending expert formulation with a painless experience.
