The VieBeauti Whitening Pen Kit is built for people who want real whitening results without the mess of strips or the expense of a dental appointment. This kit includes four whitening pens and one desensitizing pen, designed to work together as a complete routine. The whitening pens use 35% carbamide peroxide to break down years of staining from coffee, wine, smoking, and everyday food. The fine-tipped brush gives you precise control, so you can reach the edges and back teeth that most strip products miss. How to use: Twist the bottom of the pen clockwise to release the gel. Apply a thin layer evenly across your teeth, avoiding the gums. Smile for 60 seconds to keep the gel in place, then wait 20 to 30 minutes before rinsing. Avoid eating or drinking for one hour after each session. For sensitive teeth: Apply the desensitizing pen first. Wait 10 to 15 minutes, then proceed with whitening as normal. No need to rinse between steps. With consistent daily use, most users see a noticeable difference within the first week. For best results, use once or twice a day for up to 14 consecutive days, then take a 2 to 4 week break before your next treatment cycle. Compact and easy to carry, these pens fit in a bag, desk drawer, or carry-on for whitening at home, at the office, or while traveling. Designed for adults 18 and above. Not recommended for use on crowns, veneers, or severely decayed teeth. Individual results depend on original tooth shade and consistency of use.
