Frequently asked questions
Everything customers ask most about the strips, shipping and returns.
We designed the formula specifically to avoid that. Most strips rely on harsh peroxide, which is where the pain comes from. The US NOVA formula is non-toxic and sensitivity-free, so the actives lift stains without the zingy sensitivity. If your teeth are historically very sensitive, start with 20 to 30 minute sessions.
You will see a noticeably brighter smile the moment you remove your very first strip — that's the 2nd Gen purple color correction neutralizing yellow undertones. Deeper stain lift builds session by session across the full treatment.
Yes. These are designed for stubborn, set-in lifestyle stains. The enamel-safe actives get into the enamel to break down and lift years of discoloration from coffee, tea, red wine and smoking.
Yes. The formula is enamel-safe, vegan and cruelty-free, made in an FDA-registered facility. No-Mess Grip Tech keeps each strip locked to the tooth and off the gum line.
Peel the strips from the backing film with dry hands. Fit them gel-side to the tooth surface, align with the gum line and press gently. Leave on 20 to 45 minutes, then remove and rinse thoroughly.
