Fast-acting Zero Glow Teeth Whitening Gel - 4X Syringes | 44% Carbamide Peroxide Refill Review

The item arrived very quickly! I've been using it for the first few days and I'm already seeing the result! It will be great to get what I want in my teeth and keep them.

This product is amazing. I have only used it 1 time and it has greatly changed the color of my teeth. I like it, it works and it's affordable. Highly recommended

I have been using teeth whitening products for years when I want to whiten my teeth. I saw it on Revain and saw 44% with good reviews so I've been using it for a few weeks and no change. Now I think it's 44% because I had 40% and it "burns" with it. I can't even tell it's in my trays on my teeth and gums. I don't do reviews unless I think it's a product we're wasting money on, so don't waste yours on this one.

Now I think it's 44% because I had 40% and there's a kind of "burn" of it. I can't even tell it's on my teeth and gums in my trays. I do not know. I don't review much unless I think it's a product we spend money on so don't spend your money on this one.

This product has even more whitening power than the gel you get from your dentist and best of all, NO ZINGER. Everyone who whitens their teeth knows about scurvy and I haven't gotten it yet. Tip for everyone: If you don't want this product to burn your gums (which can happen because it's a strong material), apply the gel to your dental impressions. with a toothpick. This allows you to spread the gel evenly and prevent it from smearing over the gums. Overall a great product.

The strongest product (44% Carbamide Peroxide) I have ever found without a brand name. I can't pay 4x, 6x or even 10x for the same product just because of the name. It works just as well as any whitening product I've tried. Like any peroxide product, it can burn your gums if left on for a long time. I use a molded mouth card that clearly shows the impressions of the teeth and lightly mask only those areas. This keeps it off my gums and keeps it foolproof. These 4 tubes will last me many, many…
