Hard to tell if gel is applied evenly

4 years ago

Thankful to have received this product for testing purposes. The first use took quite a bit of trial and error to figure out as it took much more twisting than the directions implied. The gel/product itself is clear in color, which is probably for the best since you have to sleep with the product overnight and then brush off in morning, but I found myself wishing the gel itself was tinted or colored so it's easier to actually see how much product you're applying. After the first few uses, my results weren't ideal because the product wasn't spread evenly during application and it's hard to tell if you're applying evenly.

Yes, I recommend this product.

White pearl in a bottle!

4 years ago

By far the best whitening pen! I try different whitening pen like Reach and Active Wow etc. Which cost a lot. Very easy instruction, easy to apply on my teeth and didn't let any residue or starchy feeling, and didn't leave a bad taste in my mouth or any after taste, also no irritation on my gums or teeth, which made my experience better because I have sensitive gums. The packaging caught my eyes, red bright. My only complaint is ran out super fast wish it was more in the bottle. I will buy this product again because I see the change of color on my enamel. I have light yellow teeth, stained from coffee. Help me with a clear smile! 10/10

Yes, I recommend this product.

Works well

4 years ago

I was very impressed by how quickly this product worked. I only had to use it a few times and there was a very noticeable difference. The product was fairly easy to use. You brush your teeth then make sure they are dry. You take the pen and pump it a couple times then paint the gel on your teeth. The whole process only took a couple minutes which was way quicker than other whitening products I have tried. The only thing I would change is if maybe the gel was a different color so you know where it's been applied? It seems like sometimes I over apply and other times I under apply so it's hard to tell.

Yes, I recommend this product.

Hi there! Thanks for taking the time to share such great feedback. We're sorry to hear that the color of the serum makes it difficult to know when it has been applied. We will take this into consideration for future improvements. Have a great day!

It kind of worked

4 years ago

So it did make my teeth a little whiter but with the amount of days in a row spent using it at night I feel like they should have gotten much more white than they did, also it says you have to click the button a certain amount of times in the beginning but I had to do about twice as much as suggested to get any product to come out, I also got the product stuck to my lip or gums quite a few times and it stings very badly when it touches your skin which unless you're holding your lip completely out while also trying to apply is unavoidable, I will continue trying to use it because it's here and somewhat working but in the future I would stick to whitening strips

Yes, I recommend this product.

We are so sorry to hear you had difficulty with our pen! It can take up to 20 clicks when you first use it, however afterwards it should dispense as needed (times clicked). We would love to help you with this issue! Please reach out through any of our live channels here https://shop.colgate.com/pages/contact-us (Sunday through Friday from 8:00 a.m. to 8:00 PM EST).

No!

5 years ago

I wanted to like this product for it's obvious benefits. I normally use Crest products for whitening, but this seemed appealing. However, after the first couple of uses, the pen began to 'clump,' and dry out. Each time I would attempt to rinse the brush, but it would only help to a degree. I would have to click the pen more times than the directions indicated, and I would still end up having to clean the pen again. It left hard dried residue on my teeth, that could only be removed by vigorously brushing my teeth. The price point on this product is absolutely unjustified for its lack of follow-through. Do not waste your money.!

Great way to whiten your teeth

4 years ago

So like any other teeth whitener I was skeptical cause they all clime to do this and that.. I see my teeth daily so changes are never too noticeable. Well well well with this optic whitener I can say HELLO white teeth. I have used it for 7 days so far and I can clearly tell a difference in the color of my teeth. It is very easy to use. You simply just paint it on your teeth go to bed over night let it work its magic. I am 100% satisfied with this product. I truly enjoy the instructions that come with it. the design is really appealing to the eye and it comes with a stand so you can place it some where safely during the day.

Yes, I recommend this product.

Review of the Colgate Optic Overnight Whitening Pen

4 years ago

The Colgate Optic Overnight Whitening Pen claims to remove 15 years of stains in 1 week. As directed, I used this Pen at night and left it overnight as I slept. The precision brush allowed me to target every tooth with ease, and I had no difficulties distributing the product upon opening. I didn't experience any teeth sensitivity, and I did see a difference in my teeth color after a few uses. This Pen did leave a film on my teeth, but it wasn't bothersome while I slept. To clean the Pen, I wipe the brush with a tissue and no water. All in all, I would highly recommend this Colgate Optic Overnight Whitening Pen to my family and friends that want to whiten their beautiful smile. I plan to purchase again in the near future.

Yes, I recommend this product.

Colgate Optic White Overnight Pen

4 years ago

Overall, this is an average whitening pen. It did not drastically whiten my teeth but more so gradually would have and needed more time to get to the drastic whitening difference. It also leaves a gritty feeling on my teeth when I go to bed and when I wake up that is not pleasant. I tried to brush and floss most of it off too and still would have some residue that clung in between my teeth and would harden so it was not easily able to be cleaned off. I did enjoy how the pen felt and how easily travel able it is. Overall, I would say I was not fully blown away by this product but would be good to have in a pinch.

Yes, I recommend this product.
