Viebeauti Whitening Pen: Instant Results Without the Sensitivity We were curious about how the Viebeauti Teeth Whitening Pen stacked up against professional treatments for sensitive teeth. After using it, we’re impressed with the immediate brightness it delivers without causing irritation. The 0.2 fl oz gel, powered by carbamide peroxide, works quickly to eliminate stains—perfect for on-the-go touch-ups. The pen’s slim design makes it easy to target specific areas, and our teeth felt noticeably whiter in just a few strokes. What surprised us was how gentle it felt on our gums, even with previous sensitivity issues. While it won’t replace a dental cleaning, Viebeauti offers a viable option for those seeking a flash of brilliance without harsh side effects. We’ll definitely keep this pen in our routine for quick shine-boosts.
