·AuraGlow Extra Strength Whitening Strips deliver professional-grade whitening with 11% hydrogen peroxide — a higher concentration than most over-the-counter strips — for visible results after just 1 use and up to 10 shades whiter in 7 days. Designed specifically for stubborn, deeper stains that standard whitening strips cannot reach. What makes these strips different — dual sensitivity protection: Most whitening strips address sensitivity with a single ingredient. AuraGlow uses two. Potassium nitrate calms nerve sensitivity during whitening, while nano-hydroxyapatite (nHAp) actively remineralizes and strengthens enamel at the same time. The result is extra strength whitening with significantly less risk of the tooth sensitivity most people experience with high-concentration strips. What is nano-hydroxyapatite: Nano-hydroxyapatite is the same mineral that naturally makes up tooth enamel. While hydrogen peroxide lifts and removes stains, nHAp works simultaneously to repair microscopic enamel damage and restore mineral density — making these strips a smarter long-term choice for anyone who cares about both whitening results and enamel health. Removes stains from coffee, wine, tea, soda, smoking and aging: The 11% hydrogen peroxide formula penetrates deep into enamel to break apart stain molecules that lower-concentration strips leave behind. Effective on fresh surface stains and years of built-up discoloration caused by daily habits and natural aging. Flexible wear time — 30 minutes or up to 1 hour: The standard treatment is 30 minutes. Thanks to the sensitivity-safe dual protection formula, you can safely extend wear up to 1 hour for a more intensive whitening session whenever you want faster or deeper results. Designed to fit every smile: The top strip is a longer rectangle for full upper arch coverage. The bottom strip is rectangular rather than arched to ensure uniform coverage across all lower tooth shapes — no gaps, no missed spots, consistent whitening across every tooth. Enamel safe, cruelty free and vegan: Formulated without harsh additives. Safe for caps, crowns, veneers, and fillings — the formula whitens natural tooth enamel only and leaves dental restorations completely unchanged. Mint flavored for a comfortable, fresh treatment experience every time.
