Kobayashi Charcoal Power Toothpaste Review

The YS Beauty Lab

“The dark night gave me black eyes, I use them nonetheless seeking for the light.”

This two-line poem from Chinese poet Gu Cheng pretty much summarizes what Kobayashi’s Charcoal Power Toothpaste has to offer. With its charcoal particles, the toothpaste guarantees to prevent bad breath, whiten teeth, remove plaque and prevent tooth decay.

The idea sounds exciting – getting rid of dirt with something dark. Nonetheless, charcoal has been a well-proven effective ingredient for cleansing and removing undesirable odors. Enter the word “charcoal” on YesStyle’s Beauty page, and you shall find various cleansing products including facial masks, face washes, sponges and puffs. I’ve tried using charcoal packets in my shoe cabinet and fridge, but never on my teeth.

Not that I’m afraid of putting that dark matter into my mouth. I don’t smoke nor do I frequently drink coffee or Coke which are the common causes of teeth stains, so I don’t find myself troubled by bad breath, teeth discoloration or plaque. However I do know people who suffer from those conditions, so here I am, venturing into the dark in search of brighter smiles.

The toothpaste comes in a thick tube topped with a large screw cap. There’s no aluminum foil to protect the opening so do be careful when you squeeze it out.


With its rather watery texture, I decided to use only pea size to prevent it from dripping from my toothbrush.


The toothpaste is dark and enriched with black granules which I believe are the charcoal particles.

To my dismay, it smells and tastes like mint grape chewing gum. Fortunately it’s not the worst taste I’ve experienced among the oral care products I’ve tried. If you use Listerine frequently, then you might be able to withstand the rather strange flavor. The taste is similar, but much milder.


My teeth were tinged black upon first contact with the toothpaste. But as I continued my brushing, the black color began to dissipate into foam.


After a few minutes the darkness wase completely gone.


Upon rinsing my mouth with water, my teeth were left squeaky clean and gleaming.

I’ve yet to test out its whitening qualities, but the squeaky clean feeling is already luring me to switching from my current toothpaste brand. At US$6.9 for 100ml, Kobayashi’s Charcoal Power Toothpaste may not be the cheapest toothpaste on the market, but it’s definitely worth a try, especially for those suffering from bad breath and plaque. You deserve brighter, more confident smiles, and better kisses!
