Review on Colgate Optic White Overnight Teeth Whitening Pen: 🦷 Powerful Stain Remover for Whiter Teeth - 35 Treatments Included! by Chelsea Hernandez

The product does not work. Nothing happened when I pressed the button. I am very disappointed that I spent $30 on this. Be careful. Edit: It's been two days since I tried the product. My lip is swollen and pus is coming out. I'll call my doctor in the morning. I suspect something has come out and is reacting really badly to my lips, at first I thought the pen was empty. I will update after my meeting with the doctor. The stubble seemed dry, but I think I was wrong. I haven't added anything to my daily routine.
