Cali White Natural Teeth Whitening Gel Refills, Zero Peroxide, Botanical Formula, Vegan, Organic Whitener for Sensitive Smile, Gels Made in USA, 3X 5mL Syringes, Use with UV or LED Light & Trays

I'd about given up on ever having whiter teeth again with my teeth sensitivity issues. It was bad! Peroxide whiteners left my teeth aching for hours after using. I was skeptical about this natural whitener, but with my daughter's wedding coming up, thought I'd give it a try. IT WORKS!!! No pain and my teeth are SEVERAL shades whiter. I can't stop smiling in the mirror just to get another glimpse of them. It's boosted my confidence to smile again! Highly recommend.

It does whiten, though I would recommend springing for a corded LED activator light, as those are much more powerful than the battery powered light offered with the Cali White kits. The light they sent stopped working after 5 treatments and I’ve seen much better results with the corded LED whitener I ordered to replace it.

Can’t say how much I love this product. You only need to use it everyday when you start, but after that I’ve only needed to use it maybe once a week to keep my teeth white (they say you only need to do it once a month, but I drink quite a bit of coffee so I do it more often). This product totally works and since I have a peroxide sensitivity it’s GREAT!

This product is not gel. It's a liquid. I've tried refrigerating the vials to try to firm the product but even that doesn't work. In my opinion, this is a ripoff!

I use this with my light-activated whitening tool. Works very well. For an extra white smile, I use it for two episodes of Big Bang Theory and... Presto! Instant white teeth. I can't say the taste is good or bad, although I wouldn't swallow it. Not as chemically tasting as some others I've tried. This is my favorite whitener.

Works okay, a little expensixe for the results you achieve.

I like this better than the Crest whitening strip. This is more target to my teeth, and doesn't have a chemical burns feeling on my gums of left at recommend time. You can buy hydrogen-peroxide-free refills. It did makes my teeth whiter after a few weekly uses.

Although it takes a bit longer for the effects to occur with this product as opposed to the peroxide product, I have been satisfied with how my teeth are getting white all the while using natural harm free ingredients!! I would recommend this if you are willing to be patient and keep up with it!
