To become more Beautiful of Pores with recommended combination


As I have become older I have become more concerned about bad breath , and unintentionally had been talking almost to myself so as not to open my mouth.
I have regularly done dentist checkup and treatments. Still I had bad breath...I was surprised when I tried this product.
I was brushing my teeth really carefully, but this product has removed so much dirt.
I also gargle. Sore throat had decreased drastically.
I have also clearly noticed tongue dirt.
One month has passed since I began using this, and my dentist says that my teeth are well cleaned.

I bought it 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 want to regularly test this product.
