Colgate Optic White Overnight Teeth Whitening Pen, Teeth Stain Remover to Whiten Teeth, 35 Nightly Treatments

Works really well, but application can take time
I tend to write long reviews, so here’s a quick list of positives and negatives of the whitening pen. This may also answer some questions you have about using the whitening pen:Positives:-Actually whitened my teeth!-No bad taste-No irritation/pain-Easy to apply-Nice packagingNegatives:-Did not last as long as the box said it would (lasted 1.5 weeks instead of the 30 usages the box promised)-You have completely to dry off your teeth and then paint on the solution on each individual tooth (I personally didn’t mind this. It just took a little while to do)-If you paint over wet teeth, it will ruin the brush-The solution easily clumps up in areas on teeth after it dries (this didn’t bother me much, but thought it was worth mentioning)Okay so here’s my more in depth review:I’ve tried just about every whitening toothpaste on the market, charcoal, baking soda, and more, with no results. I heard about this pen and thought I’d give it a try. I was a bit nervous because I can have sensitive gums, but I felt no irritation whatsoever! The pen lasted exactly a week and a half before I used it all up (so it did not last the 30x stated on the box!). In that time, I can honestly say my teeth look whiter! I was pleasantly surprised. Believe me, the yellow on my teeth was stubborn! I may purchase the pen again to whiten my teeth even more.However, I noticed a few things about the pen that might be considered negatives to some people. First of all, you have to COMPLETELY dry your teeth before “painting” on the whitening solution with the pen. Otherwise, the solution gets all clumpy and dries up on the brush, which will ruin it. Also, be aware that the pen paints this solution on your teeth and sort of leaves a thin film/coating over your teeth overnight. The solution doesn’t have a taste or anything, but you will definitely want to brush your teeth in the morning to get it all off. Also, be aware that the solution will clump up in places on your teeth when it dries.I was not aware that that was how the pen works when I bought it, but looking back, I noticed that most of the negative reviews focused around the white clumpyness of the solution on your teeth. This honestly didn’t bother me much, though it was a little bit of a hassle to dry off my teeth and get an even coating on each tooth.Additionally, you will only be able to whiten your front teeth, as it is to hard to dry off and paint the teeth at the back of the mouth.Overall, I am pleasantly surprised and impressed by this whitening tool. I’ve tried so many different things and this is the first that has worked! If you are okay with the few “negatives” than definitely purchase this product! I would purchase this again!As a note, I tried to take before and after pictures but because of bad lighting, they didn’t turn out. But I did see a huge improvement in my teeth’s whitening!

On To The Next
This wasn’t the right teeth whitening product for me. It seemed easy enough to use, but I could never tell if I had applied too much or too little. I always had a feeling that it was too little and that it wasn’t staying on my teeth through the night. I didn’t see much of a change so I lost interest pretty quickly. I bought the product at a fair price on sale so I did not feel like I spent too much on something that didn’t work.

Recomendable

Doesn’t work

Creo que al menos a mí, sí me funcionó.Eso sí, hay que ser constantes y disciplinados con el uso para obtener los mejores resultados!Algo que no me gusto, es que al parecer el producto se seca dentro de la pluma dispensadora y a veces se traba el botón para sacar el producto y se apelmaza en la punta del pincel. Fuera de eso es recomendable!
