To become more Beautiful of Pores with recommended combination


As I have become more concerned about bad breath with my age, when I was talking, I was mumbling unintentionally so as not to open my mouth.
I have regularly done dentist checkups and treatments, but for some reason, I still had bad breath...I was surprised when I tried this product. I had been brushing my teeth really carefully, but this product has removed so much dirt.
Also, I gargle with this and my sore throat has decreased drastically.
Besides, this product clearly shows the dirt on the tongue.
One month has passed since I started using this, and my dentist says that my teeth are well cleaned.

I bought this out of curiosity.

I compared the dirt in my mouth immediately after waking up in the morning, before and after brushing teeth after meals etc., and I was shocked to see the distinct difference.
I will buy this repeatedly to check my mouth regularly.
