Photo Review of COLGATE TOOTHPASTE OPTIC WHITE OVERNIGHT PEN 1 PK

I have used this product once before and I am really impressed with the results. You simply clean your teeth as normal, dry your teeth and apply the gel with a small brush (included). You then sleep with the gel on your teeth and remove the following morning. With 3% hydrogen peroxide, this is the highest amount you can purchase in over-the-counter whitening products in Australia. After two weeks if treatment, I really did notice a difference in the brightness of my teeth. I would recommend this product, at $38 a packet when not in special, it is expensive but I feel like it’s worth it.
