Colgate Optic White renewal.
I received this product to try as a product review. This Colgate Optic wake renewal claims remove 10 years of yellow stains it's high-impact white. It includes 3% hydrogen peroxide. I really think it works great I like it better than the original Colgate Optic White. I feel like I seen a difference after the first use so I continue to use it for twice a day for about 2 weeks now. I will definitely be purchasing this product.
