Teeth Whitening Gold Serum Pen

I almost didn't order this because I thought whitening pens might be too good to be true. Three weeks in and it's literally the only one I reach for now. Got stopped twice at a brunch spot last weekend — one friend asked if I'd had work done. The gel goes on smoothly and the finish looks brighter depending on the light, kind of noticeable in the best way. Quick-drying but not sticky, so it's easy to use and comfortable. Worth every penny.
