オプティックホワイト ホワイトニング パープルセラム（ポンプタイプ）

The product claims to neutralize yellow tones using color-correcting technology, and I did notice a temporary brightening effect after application. However, the results are more of an optical illusion rather than a deep whitening treatment. If you’re looking for an instant, subtle boost before an event, this works well, but it doesn’t replace professional whitening or long-term treatments like hydrogen peroxide-based gels.

Not sure of the results for this product unfortunately the bubblegum like taste was not my thing.

So, I've seen all these purple toothpastes advertised on socials, and really didn't believe the hype. I've also had my teeth professionally whitened and was happy enough with the result. Certainly not movie star" results and they dull again with time (coffee and red wine!) So I was very excited when my packaged arrived! I went straight off and tried it immediately after I tore open the packaging! I absolutely LOVE the taste of the peppermint and yuzu. Extremely refreshing! But... does it lighten your teeth? Made my lips purple for a bit there, and it does seem to take some of the yellow away or disguise it, who knows! I've been using it before I go out or am online for meetings. It's not going to leave your teeth looking like you have painted them with liquid paper, or blinding to look at (thank goodness!), but it does leave you with a nice natural, slightly brighter smile. And that leaves a nice taste in everyone's mouth!! (Excuse the bad pun!)

Trying to get the bottle’s pump to work first time took ages, thought I got a broken bottle but eventually got there. The serum has helped a little bit but not significantly.

What a transformation. We used the Colgate Optic White Purple Serum recently. And even our dentist was impressed with a lot less yellow on our teeth. Amazing!!

This whitening serum was ok. It had a pleasant taste and was not harsh on my teeth. I do have quite stained teeth due to my 4 cup a day coffee habit and did not really notice any difference in the colour of my teeth after the 14 day trail.

Overall the product worked well, there wasn't as much of a drastic change as I was hoping for but if used twice daily it was effective in ensuring I had a bright white smile. I would recommend this as a effective quick solution.

Very happy with this product. Its simple to use whitening is noticeable. Definitely recommend!

I used this product twice a day for 2 weeks and I feel as though it has started to improve the whiteness of my teeth. I feel with longer useage it will continue to improve. I enjoyed the mild bubblegum flavour also.

Diminish the yellow colour of my teeth without hurting them. Keep my teeth fresh with the mint flavour.
