Whitening before bedtime
Need the discipline to remember to use it at night before sleeping. Teeth needs to be dry n must apply carefully without touching the gums.

Whiten my teeth while I sleep
This Colgate optic white pen is so easy to apply on my teeth. It leaves a white coating on my teeth and slight whitening is noticed when I brush it off the next morning!

1ST TIMER
Easy to apply to your teeth just before bedtime. At first, I was worried that it will make me feel uncomfortable but you just have to paint it onto your teeth and after a while, it will dry with a layer on it. Wake up just brush it off. I had some sticking near my gums so I will use my floss to clean it up

A gentle but slow way to whiten tooth
This product does whiten teeth but may take a longer time to show results. The gel is gentle but rather troublesome to use, since it requires teeth to be at least somewhat dry for the application of the gel. I have sensitive teeth but this did not cause any irritation. I brought this from Lazada and the price fell to aroung $15 on a sale, so those interested may want to wait for a sale.

Convenient
I use this daily every night for about a month now and I can see that it has gradually whitened my teeth. I’m so much more confident about my smile now! It’s also really convenient and fuss free to use too.

Not easy to use
Application is not easy. Very cumbersome to use and it leaves a residue that is difficult to brush off. When touching any part of your mouth by accident, it leaves a stingy and numbing feeling. Did not see any visible results in 3 weeks either. Photo of side by side comparison for reference. Would not recommend using.

Sleep and wake up with brightened smile
Very convenient to have teeth brightening from the comfort of my home. Works effectively in brightening my teeth with little efforts put in!

Serves its function
Great function and works but felt like I need to apply multiple coats Vs just once for a better effect. Instructions for this were quite vague and had to find online. Recommend as a fix for more consistent ppl as you have to apply everyday.

Can do better
The product is not as good as what I thought it would be. It makes my teeth worst and become more sensitive than before. My gum would bleed when I brush my teeth with my soft bristles tooth brush. Dislike the feeling of having a layer of coating. It is difficult to brush it away, had to scrap it instead. Had to click many times for the product to slowly oozes out.
