Can’t decide on just one flavor? Get all four in the Effervescent Breath Crystals with IsoVoxy multipack.

Birchbox Breakdown

If you miss spending your summer days with nothing but time to kill and a packet of Pop Rocks, then you’ll be happy to find these Effervescent Breath Crystals, which attack halitosis with the ferocity of that sweet, crackling candy. The science rests on a mix of bacteria-fighting ingredients that, when in contact with germ-filled teeth and gums, erases the effects of embarrassing odors caused by things like coffee, onions, and garlic with a series of mini-mouth explosions.

How to Use

Pour the contents of an individual pack into your mouth and swish the crystals around, rubbing them against teeth and tongue. Let them dissolve or swallow and enjoy peppermint-fresh breath!

Peppermint: Isomalt, Carbon Dioxide, Xylitol, Natural Peppermint Flavor, Zinc Gluconate, Sunflower Oil, Sucralose.

Spearmint: Isomalt, Carbon Dioxide, Xylitol, Natural Spearmint Flavor, Zinc Gluconate, Sunflower Oil, Sucralose.

Lemon: Isomalt, Carbon Dioxide, Xylitol, Natural Lemon Mint Flavor, Zinc Gluconate, Sunflower Oil, Sucralose.

These kind of pop in your mouth, which is a little unexpected at first, but once you get used to that feeling, they work great and freshening your breath and last a long time.

Fun and Refreshing
SampledPurchased

These are just a fun way to freshen up your breath. It's like a pop rock version of mints. They could probably be stronger though

These were good to carry around in a purse and did freshen my breath, but I don't think it lasted as long as it should have.

Would not recommend

Unless you really struggle with bad breath, I would not recommend this product. For me at least, it is much easier just to brush my teeth.

Refreshing Poprocks
SampledPurchased

If you don't like retro (is it retro already?) candy, Pop Rocks, then you will not like these breath crystals.

As it turns out, I really liked them. Tastes like candy from my childhood but is cleaning my mouth. BRILLIANT

My mom also loved these, especially the lemon mint.

Only downside, the expiration date. I wish these stayed fresher longer.

Not my favorite
SampledPurchased

I tried in my sample and loved the pop rock sensation with a cleansing bonus. Although I ordered used again and for some reason it gave my mouth a horrible after taste. Darn it. I was so excited too. My kids wouldn't eat them either. Sorry.
