LUCKIN SMILE 10pcs Teeth Whitening Gel Refill with 35% Carbamide Peroxide Suitable for Sensitive Teeth Whitening, Teeth Whiteners Used in Conjunction with Teeth Whitening Kits

The teeth whitening gel works great. After using the gel twice, my teeth were already whitening up. You get a lot of gel for the money! I recommend this gel for whiter teeth.

# 1 - Wish the ingredient list was fully disclosed on the ad page.All I know per the ad, is that it is 35% Carbamide Peroxide, which I had to look up what that is. VS. hydrogen peroxide - which is the most commonly used tooth whitening ingredient.The buyer - now must become more educated. There are differences from my internet research In that according to multiple articles, carbamide peroxide takes longer to "breakdown", which I interpret takes longer for tooth whitening, while hydrogen peroxide can see results in 10 minutes. I'm not a dentist, I'm not a hygienist, I'm not a chemist or have much scientific knowledge, but I do know how to do a basic internet search.The ingredients when you get the box state: UREA PEROXIDE which I had to internet search that it was Carbamide Peroxide. but I don't know how to confirm that it is 35% Carbamide Peroxide.I didn't mind the effort to change out the applicator. I have purchased other syringe type whiteners, and just had to snap off the end, not first swap out the syringe tip.I can't say that it works. as it will take time to see results.I will have to do more research and compare to other whitening syringes that do have hydrogen peroxide, and prefer to buy from a seller that discloses the ingredients on the ad page.

I am Alway buying teeth whitening

This is my third time order. The brand is great. Has written my teeth up a lot. Still getting there as they were really bad. The taste is great

Really works to whiten teeth! Highly recommend.

These are typical whitening gel syringes. They are push bottoms with the gel that gets squeezed into a teeth tray. You need to dry your teeth first and then let sit for 15-30 minutes and then do not eat or drink for 30-60 mins afterwards. The effects vary per person depending on the level of stains and how often you rewhiten your teeth. They have extra tips if you have a smaller tray, but i just used the syringe itself, pushed out what I needed and replaced the cap.This is a 10 pack and it worked just as much as any other OTC product.I received this product for free through Vine, and I am leaving this review voluntarily.

Ok so I’ve always had issues with sensitive teeth and teeth whitener always leaves me in pain I even use a whitener with less bleach and more coconut oil and still in pain. I keep doing it because I love white sparkling teeth. Ive only used this once and already feeling great! No pain or aching, no sensitivity to cold or hot definitely think it’s worth it. Product says you can leave it on anywhere from 5-60 minutes I left it on for 30 if anyone is wondering.. also I barely used up a quarter of one syringe this will last a good while

I am at Teeth Whitening Specialist and I use this for my clients after I do an aggressive whitening and it seems to work just right! I give them some to take home and haven’t had anybody complain, so seems to be doing exactly what it meant to do
