3PC 30D Whitening Power Duo

The two 1oz gels lasted me a full month of nightly applications, and the pen is perfect for quick touch-ups on the go. My teeth look noticeably brighter after just the first week, though I did have to be careful not to overdo it on sensitive spots.

The advanced pen is so convenient for touch-ups after coffee—I just twist and swipe. My teeth feel noticeably smoother, and the whole kit is still going strong after three weeks of nightly use.

The pen is surprisingly easy to handle, and each gel tube lasted me a solid two weeks of nightly use. My teeth feel noticeably smoother, and the whole kit fits neatly in my bathroom drawer without taking up space.
