After trying several brands, I’ve gathered my thoughts and experiences to help you navigate your own purchasing journey. Here’s everything I learned about this unique toothpaste.
Understanding Niacinamide
Niacinamide, also known as vitamin B3, has been praised for its skin benefits, such as improving skin tone and texture. I was intrigued to see if it could offer similar benefits for my teeth.
