White Assist lightens your teeth up to three shades in less than a month. It's perfect for smokers, soda and coffee drinkers. Just apply a few quick strokes of this minty fresh, maximum-strength gel to your teeth anytime you want the "just whitened" look. 12% stabilized hydrogen peroxide. Refreshing peppermint flavor. Two .85 oz. pens. 30 applications per pen.
I was so excited to try this teeth whitening pen and then i used it for 2 weeks and it didnt even show result so then i used it for another week and still no result im very unsatisfied with this product. Quit selling it.
Bottom Line No, I would not recommend this to a friend
