Whitening Serum 3.0ml

This was astonishingly effective! I've always been interested in teeth whitening options and this is the best I've tried. I left it in overnight but could see it was working even after less than 30 mins.A few comments:1. It comes in a syringe-style tube and there's a very small cap at the end; to reseal, you just need to flip the same cap over - you don't need anything special to reseal the tube.2. You only need to dispense a tiny amount into trays or a retainer (it was formulated for use with these). I used mine with retainers and had zero problems getting the product to cover the teeth.I anticipate getting multiple uses out of a single tube, since only a tiny amount is needed each use. I haven't been convinced by other whitening options others swear by (like Crest Whitestrips), so if you want to try something else, I completely vouch for this. It's very convenient to use (no fiddling with strips) and effective - I think this is because the gel formula coats teeth more thoroughly, plus the product is for use with trays/retainers which are well-molded to the teeth.

It’s working on my teeth . I use aligner and teeth are getting whiter just make sure to pour a small amount on aligner because if not you will have to spit the remainder and it can feel gross. Use as instructed.

Really impressed by how well this product works. I saw results after just two applications. Works better than a whitening toothpaste. Careful when you first open it. The tip applicator is flimsy, and I broke it off initially. I was able to get it back on, but I lost some of the product in the process.

Great idea in theory, but it's finnicky to use. The syringe is flimsy and the tip that plugs it is tiny and hard to put back in. It's easy to use too much and make a mess. Today the plunger fell off (flimsy) and I have no way of putting it back in the syringe without squeezing all of the product out. It's a shame because I really liked the idea of being able to whiten my teeth while wearing my aligners but this is more trouble than it's worth. I'll probably just stick with strips going forward.EDIT: They kindly offered a full refund. Excellent customer service and I appreciate them wanting to make it right.

So glad I found this! I have used similar whitening products that I purchased through my dentist, but with a much stronger percentage of the active ingredient. The one I purchased at the dentist irritated my gums. This formula is very gentle and I saw a difference immediately. This is gentle and whitens teeth gradually.

This is a great boost in whitening and it tastes good.

I had sensitive teeth and this didn’t bother them! Could tell a difference with one or two uses.

I used this product while wearing Invisalign retainers. Just apply at bedtime. It works really well to the point I use it about one week per month.
