Excerpt:

We’ve tried countless whitening strips over the years, often trading brighter smiles for stinging sensitivity. But the Lumineux 21 Treatment Strips have刷新ed our expectations. Promising peroxide-free whitening that’s enamel-safe, we were skeptical—until we used ours. The key? No harsh chemicals, just gentle yet effective advancements in formulatation. Our favorite part? Truly zero sensitivity. Unlike other strips we’ve used that left our teeth6 tingling after just a few days, Lumineux treated our teeth with kindness. Dentist-developed and patented, ours were clearly designed with long-term use in mind. After two weeks, our teeth were noticeably brighter, and not a single twinge of pain. If you want a brighter smile without the trade-off, we wholeheartedly approve these strips.
