I like using this to keep my teeth white and it's a great deal

I'm not exaggerating here, as I don't write too many Reviews, unless I truly believe in the Product or the Company.
I have used tons of Teeth Whitening Treatments, White Strips, and also the expensive Whitening Process from the Dentist...., and I AM ABSOLUTELY AMAZED AT THE LUELLI WHITENING KIT.
I have very very sensitive teeth. I actually grind my teeth. And, many of my teeth are not only worn through the Enamel. But, my Dentist actually told me that some of my teeth are actually worn down to the Dentin. I didn't even know what Dentin was.

But, the point to this, is that every single Teeth Whitening Treatment I have tried in the last 5-7 years has given me so much pain and sensitivity that I had to stop the process a few days into it.

And, I honestly was thinking that there was no way that this LUELLI Teeth Whitening Kit was going to remotely work. Especially within the "claimed" 10 minute sessions.

All I can now say is WOWWWW!
I have used this treatment for only 6 days in a row, for only 10 minutes each time. (as I was concerned that the pain would come if I went for longer times).

AND, IM NOT EXAGGERATING AT ALL...., BUT IN 6 SESSIONS, MY TEETH ARE ALMOST 50% WHITER.(with only 10 minute sessions).
And, I've only had to use the
"Pain Relief Gel" once or twice. And, to be honest, it wasn't really necessary. The pain was minimal. But, I used the "Pain Relief" Gel, just in case the Pain got worse thru the night.
It didn't get worse at all!

I truly don't actually understand how this Whitening Treatment can work so well. All while using a very similar Hydrogen Peroxide Formula like all the Teeth Whitening Systems use. There must be some "Inactive" Ingredients that have been added to the Product, to produce synergistic results. Or, LUELLI has just produced the perfect amount and combination of ingredients that is also perfectly "activated" and enhanced by the Blue LED LIGHT (which I actually do have a vast knowledge of the different Wave Spectrums of Light and the Nanometer Wave Length that produce different benefits on the Human Body. I humbly own several
Health Spa's and Salons..., and we have many different
Light Therapy Treatments(from Blue Light, Red Light, Near Infrared Light, to Full Spectrum Far Infrared Light).
So, the Blue LED Light does definitely increase the results of any Whitening System. But, I've used it with other Teeth Whitening Treatment before.

And, I've never gotten these results before (without the intense pain).

UNLESS THE INCREDIBLE WHITENING RESULTS FADE AFTER 2 WEEKS OF STOPPING THE USE OF THIS PRODUCT...., this is the best product I've used in 20 years. (P.S. I did my Dentist's Whitening Treatment about 18 years ago. It worked! But, was soooo painful and expensive).

And, trust me, if the great results fade after 2 weeks, I will update my review.

I've also tried to add a picture, as I actually feel great "smiling" again in all my pictures now. But, my Phone is not letting Amazon access my Camera for some reason.

Amazing Product. 50% whiter teeth in 6 x 10 minute sessions, for 6 consecutive days.
I CANT WAIT TO SEE THE RESULTS AFTER THE RECOMMENDED 14 DAY USE.

Buenísima

I've used several whitening products but this one is the real deal. Every-time I use it I am blown away at how white my teeth are.

Maybe I had my expectations too high, but I had hoped for more of a difference in my first set of treatments. I did 10 days (consecutively except for 2 days that I missed, but I did it the following day when I missed one) for 20-30 minutes each. I really only got 1-2 shades whiter. However, I only used 1 of the 3 whitening syringes, so after a couple of weeks of letting my teeth "rest" I know I'll be able to do another round of treatments and get to the shade I want.

Very pleased with the lack of sensitivity. I have tried Crest white strips before and it made my teeth unbearably sensitive. This didn't seem to effect them as much. I used the blue re-calcifying tube 3 times throughout my first 10-day round of treatments when I felt my teeth starting to get tender, and it seemed to really get the job done.

What I was not prepared for was the extremely time consuming process this entailed! The instructions do not stress just how important it is to avoid getting the stuff on your gums! For my first treatment I applied the serum into the tray like it said, but some of it squished up onto my gums and it literally felt like acid! It was unbearable after a couple minutes so I had to stop and wipe it all out and reset - when I did I saw that the spots where it had touched my gums were totally bleached! They were still burning when I went to bed an hour later. So I switched to using a q-tip to carefully apply the serum directly to my teeth before inserting the tray and the light.

That worked, but by the time I dried my teeth (which you really need some kind of lip guard to do successfully, I used those things from the Watch Your Mouth game), switched the tip on the syringe, applied the serum, let it work for 30 minutes, wiped it out, and cleaned off the tray, each treatment took over an hour. That's not including the times I did the re-calcifying treatment afterwards. Not a deal breaker for me but be warned, it's not a quick process.

Overall I'm happy with this. My teeth are whiter without being sensitive, and I have enough product left that I feel confident I can get to the shade I want without having to buy more. That's really all I can ask for such a great price.
