Effective Whitening, Thoughtfully Made
You shouldn’t have to choose between results and care. Astra uses 10% hydrogen peroxide for noticeable whitening paired with hydroxyapatite to help strengthen enamel, not weaken it. It’s the kind of formula we’d want in our own routines: safe, effective, and made with purpose.
Most users experience little to no sensitivity. Astra is formulated with hydrogen peroxide for effective whitening and hydroxyapatite to help protect enamel and reduce irritation. If you’re prone to sensitivity, try shorter sessions or space out treatments.
Many users notice visible whitening within a few days, with full results after 7–14 consistent uses. Results can vary depending on stain severity.
Yes. Astra is enamel-safe when used as directed.
Results typically last several months to years, depending on your lifestyle.
For longer-lasting brightness, avoid heavy-staining foods and drinks like coffee, wine, and tea, and consider touch-ups every few months.
You can use Astra strips daily for up to 14 days for optimal results. After that, we recommend taking a break before beginning another round if needed.
Astra is safe for most dental work, but whitening results may vary. The strips do not change the color of crowns, veneers, or fillings.
Absolutely. We only use safe, effective ingredients including: peroxide, hydroxyapatite, glycerin, menthol, and a few others that support texture, freshness, and stability. Every ingredient has a purpose, and nothing harmful or artificial is added.
Astra uses 10% hydrogen peroxide (the same concentration found in many in-office treatments) to deliver faster, deeper whitening, without trays or gels.
