I am grateful to colgate for these two game changing products, the (Optic White Oxygen Toothpaste and Optic White Overnight Whitening Pen) for I finally got the white smile I’ve been longing for
My teeth are white and brighte I saw results in +-6 days using the overnight whitening pen and toothpaste This product is definitely more effective that any other product I’ve used before. I will definitely be purchasing the products monthly. I highly recommend this product, big thumbs up colgate.
